52 | 53 | 54 | 55 | ## About 56 | 57 | **The BIM Whale** (Swedish: _BIM-valen_) is a project about the Industry Foundation Classes (IFC) format. 58 | The aim of this project is to: 59 | 60 | > I: Introduce and explain the basics of IFC schema 61 | 62 | > II: Teach people how to parse an IFC file and retrieve basic information 63 | 64 | In more specific terms, the goal of this project is to: 65 | 66 | > A: Provide a simple and fast IFC parser 67 | 68 | > B: Provide learning resources (documentation, videos, power points) to people within the AEC industry 69 | 70 | **Goal A** has been realized as **BIMWHALE.js**, i.e. this repo. 71 | BIMWHALE.js is a simple client-side IFC parser built using TypeScript. 72 | 73 | Please note that the BIMWHALE.js is **NOT** supposed to be an all singing, all dancing parser. 74 | This project is only looking to parse information that we know exists, so-called `User Defined IFC Property Sets`. 75 | 76 | Again, the focus with The BIM Whale Project is to educate people. 77 | The code itself and its functionality are secondary. 78 | 79 | Explore the [docs](https://andrewisen.gitbook.io/bim-whale/) for more information. 80 | 81 | 82 | 83 | ## FAQ 84 | 85 | **Question:** What does _The BIM Whale_ do? 86 | 87 | **Answer:** Parse so-called `User Defined IFC Property Sets` from an IFC file 88 | 89 | ## 90 | 91 | **Q:** What does _The BIM Whale_ NOT do? 92 | 93 | **A:** Parse entity attributes, parse geometry, follow the EXPRESS standard, etc. etc. 94 | 95 | ## 96 | 97 | **Q:** What is an IFC file? 98 | 99 | **A:** Industry Foundation Classes (IFC) is a standardized, digital description of a BIM model. See [IFC](https://en.wikipedia.org/wiki/Industry_Foundation_Classes) for more information. 100 | 101 | ## 102 | 103 | **Q:** What is a STEP file? 104 | 105 | **A:** A STEP-File is the format IFC uses. See [ISO 10303-21](https://en.wikipedia.org/wiki/ISO_10303-21) for more information 106 | 107 | ## 108 | 109 | **Q:** Is this code "hand made"? 110 | 111 | **A:** Yes, the code is hand made. The parsing is not derived from an EXPRESS definition. 112 | 113 | ## 114 | 115 | **Q:** Is the code ready for production? 116 | 117 | **A:** No, not yet. See [open issues](/issues) for more info 118 | 119 | ## Getting Started 120 | 121 | 1. A compiled _JS bundle file_ is available here: 122 | 123 | [https://cdn.jsdelivr.net/gh/andrewisen/bim-whale/dist/BIMWHALE.min.js](https://cdn.jsdelivr.net/gh/andrewisen/bim-whale/dist/BIMWHALE.min.js) 124 | 125 | 2. Add it to your project 126 | 127 | ```html 128 | 129 | ``` 130 | 131 | 3. Use the FileReader API and create a new `IfcFile` object 132 | 133 | ```javascript 134 | // The libary is called: BIMWHALE 135 | var fileReader = new FileReader(); 136 | fileReader.onload = function (e) { 137 | const lines = e.target.result.split(/\r\n|\n/); 138 | let ifcFile = new BIMWHALE.IfcFile(lines, config); 139 | ifcFile.parseIfcFile(); 140 | }; 141 | fileReader.readAsText(file); 142 | ``` 143 | 144 | 4. See the docs for more information: [docs.bimvalen.se](docs.bimvalen.se) 145 | 146 | ## Local Development 147 | 148 | These next steps will guide you to set up your own development platform. 149 | 150 | ### Prerequisites 151 | 152 | This repository uses Deno as the runtime for TypeScript. 153 | 154 | - Install Deno. 155 | See instruction at [https://deno.land](https://deno.land) 156 | 157 | ### Installation 158 | 159 | 1. Clone the repo 160 | 161 | ```shell 162 | git clone https://github.com/andrewisen/bim-whale.git 163 | ``` 164 | 165 | 2. Replace the following files with your own content. 166 | 167 | - `index.ts` 168 | - `src/config.ts` 169 | 170 | The easiest approach is to copy content of the `example.NAME.ts` file. 171 | 172 | **In other words:** 173 | Replace `index.ts` with the content inside `example.index.ts`. 174 | 175 | 4. Make sure you update `src/config.ts` and provide a correct **filePath**. 176 | You can download some sample files here: [https://github.com/andrewisen/bim-whale-ifc-samples](https://github.com/andrewisen/bim-whale-ifc-samples) 177 | 178 | 5. Check if Deno is working 179 | 180 | ```shell 181 | deno run --allow-read checkDeno.ts 182 | ``` 183 | 184 | Any errors until this point are likely due to Deno. 185 | Submit an issue if have any problems. 186 | 187 | 188 | 189 | ## Usage 190 | 191 | - Run the app with: 192 | 193 | ```shell 194 | deno run --allow-read index.ts 195 | ``` 196 | 197 | ### SimpleWall Sample File 198 | 199 | Download the `SimpleWall Sample File` [here](https://github.com/andrewisen/bim-whale-ifc-samples/tree/main/SimpleWall). 200 | The sample consist of: 201 | 202 | - A wall 203 | - A door 204 | 205 | Here's a screenshot: 206 | 207 | ![Screenshot](https://raw.githubusercontent.com/andrewisen/bim-whale-ifc-samples/main/SimpleWall/Screenshots/Screenshot_2.png) 208 | 209 | The IFC file has a **Property Set** called `Custom_Pset`. 210 | Please note that the file only contains dummy data. 211 | 212 | ![Screenshot](https://raw.githubusercontent.com/andrewisen/bim-whale-ifc-samples/main/SimpleWall/Screenshots/Screenshot_21.png) 213 | 214 | Make sure to update `src/config.ts` and provide a correct **filePath**. 215 | You should get the following result: 216 | 217 | ```javascript 218 | { 219 | TypeMark: "_TYPE-MARK_", 220 | Keynote: "_KEYNOTE_", 221 | StoreyName: "Level: Level 1", 222 | TypeDescription: "_DESCRIPTION_", 223 | StatusConstruction: "New Construction", 224 | NetArea: "14.04739", 225 | Height: "4000.", 226 | Width: "200.", 227 | Length: "4000.", 228 | Hyperlink: "_URL_" 229 | } 230 | { 231 | TypeMark: "20", 232 | Keynote: "--KEYNOTE--", 233 | StoreyName: "Level: Level 1", 234 | TypeDescription: "--DESCRIPTION--", 235 | StatusConstruction: "New Construction", 236 | NetArea: "3.18957899999998", 237 | Height: "2134.", 238 | Width: "915.", 239 | SillHeight: "0.", 240 | Hyperlink: "--URL--" 241 | } 242 | ``` 243 | 244 | **In summary:** 245 | We have performed a simple parsing. 246 | 247 | We have only included `walls` and `doors` in our config file. See: 248 | `const selectedEntities: string[] = ["IFCDOOR", "IFCWALLSTANDARDCASE"];` 249 | 250 | **TODO** 251 | 252 | 253 | 254 | ## Roadmap 255 | 256 | This project is still in it's early development. And yes, it still has some bugs. 257 | Please be patience! 258 | 259 | See the [open issues](/issues) for a list of proposed features (and known issues). 260 | 261 | 262 | 263 | ## Contributing 264 | 265 | This project is still in it's early development. 266 | But, any contributions you make are **greatly appreciated**. 267 | 268 | 1.

"Function" 123 | * 2. Indefinite attribute 124 | * 3. Nested attribute 125 | * 4. References 126 | * 5. Integers 127 | * 128 | * ### 1. Functions 129 | * Example: 130 | * 131 | * ```javascript 132 | * IFCIDENTIFIER('Outside door') 133 | * IFCTHERMALTRANSMITTANCEMEASURE(3.7021) 134 | * IFCTEXT('') 135 | * IFCLOGICAL(.U.) 136 | * ``` 137 | * 138 | * For the sake of simplicity, let's call and treat these as JavaScript functions. 139 | * Note that each function has different ways to pass in parameters. 140 | * Some parameters are enclosed with apostrophe, and some are not. 141 | * 142 | * We need a RegEx that takes this into consideration. 143 | * The simplest form is: 144 | * `[A-Z]+\('[a-zA-z_ ]+'\)` 145 | * 146 | * Let's take the first function `IFCIDENTIFIER('Outside door')` as an example. 147 | * The RegEx will find us the name of the function... 148 | * 149 | * However, this is to no good use yet. 150 | * We need to capture both the _function name_ and the _parameters_, i.e. __IFCIDENTIFIER__ and __Outside door__ 151 | * 152 | * Our RegEx now becomes: `([A-Z]+\()'([a-zA-z_ ]+)'\)` 153 | * It is crucial that you understand what this RegEx mean... it will only get more difficult from here. 154 | * 155 | * Anyways, we can substitute our string using the expression `$1$2)`. 156 | * 157 | * __UPDATE:__ This approach has been replaced with a new one. 158 | * See [Issue #4](https://github.com/andrewisen/bim-whale/issues/4) for more information. 159 | * 160 | * ### 2. Indefinite attribute 161 | * Example: `#764= IFCRELDEFINESBYPROPERTIES('0Jv9wzDiT2Fx3l2pN5PrZ7',#42,$,$,(#140),#752);` 162 | * 163 | * _Indefinite attribute_ are parameters that has not been assigned. These are represented with a dollar sign (__$__). 164 | * Note that a dollar sign might appear in the UIID, e.g. `2HlE6XRD5D2u$q88QiyvCI` 165 | * 166 | * One can simply assume that _indefinite attributes_ __ALWAYS__ begins with a comma (and not a character). 167 | * 168 | * __UPDATE:__ This approach has been replaced with a new one. 169 | * See [Issue #4](https://github.com/andrewisen/bim-whale/issues/4) for more information. 170 | * 171 | * ### 3.

Indefinite attribute 95 | * Example: `#764= IFCRELDEFINESBYPROPERTIES('0Jv9wzDiT2Fx3l2pN5PrZ7',#42,$,$,(#140),#752);` 96 | * 97 | * _Indefinite attribute_ are parameters that has not been assigned. These are represented with a dollar sign (__$__). 98 | * Note that a dollar sign might appear in the UIID, e.g. `2HlE6XRD5D2u$q88QiyvCI` 99 | * 100 | * One can simply assume that _indefinite attributes_ __ALWAYS__ begins with a comma (and not a character). 101 | * 102 | * __UPDATE:__ This approach has been replaced with a new one. 103 | * See [Issue #4](https://github.com/andrewisen/bim-whale/issues/4) for more information. 104 | * 105 | * ### 3. Nested attribute 106 | * Example: `#810= IFCPROPERTYSET('0eCyo1mQf61RRDb8LkFhbB',#42,'Other',$,(#781,#782,#783,#784,#785));` 107 | * 108 | * The _nested attributes_ are the ones enclosed by parentheses, i.e. __#781,#782,#783,#784,#785__. 109 | * We need enclose them with square brackets. 110 | * 111 | * ### 4. References 112 | * Example: `#219= IFCWALLSTANDARDCASE('1F6umJ5H50aeL3A1As_wTm',#42,'Basic Wall:Bearing Wall:346660',$,'Basic Wall:Bearing Wall',#188,#215,'346660');` 113 | * 114 | * The _wall entity_ is referencing the entities __188__ and __215__. 115 | * These references need to be enclosed by quotations marks. 116 | * 117 | * Please note that references inside _nested attributes_ also need to be enclosed (see example above). 118 | * 119 | * ### 5.

24 | 25 | ## Introduction 26 | 27 | The primary docs for **The BIM Whale Project** can be found at: 28 | [https://andrewisen.gitbook.io/bim-whale/](https://andrewisen.gitbook.io/bim-whale/) 29 | 30 | The purpose of this website is to provide additional documentation. 31 | This site will focus on the code itself; the classes and methods used. 32 | 33 | Please note that actual source code is **NOT** included here. 34 | This site is built using [TypeDoc](https://typedoc.org). 35 | The content is automatically generated from the TypeScript source code. 36 | 37 | Again, to clarify: 38 | This documentation will go into more details. 39 | It will (try to) explain how the code works. 40 | 41 | If you feel overwheled by this, then head back to the [original documentations](https://andrewisen.gitbook.io/bim-whale/). 42 | 43 | ## Code Architecture 44 | 45 | ### Folder Structure 46 | 47 | The overall folder structure is shown below. 48 | 49 | ```text 50 | bim-whale 51 | ├───dist 52 | └───src 53 | ├───utils 54 | ├───config 55 | ├───step-parser 56 | │ └───step-parser.ts 57 | └───ifc-parser 58 | └───ifc-parser.ts 59 | ``` 60 | 61 | Please note that the `ifc-parser` is an extensions of the `step-parser`. 62 | Each method is put inside it's own file to keep things more organized. 63 | 64 | ```text 65 | bim-whale 66 | └───src 67 | └───ifc-parser 68 | ├───ifc-parser.ts 69 | └───methods 70 | ├───parse-ifc-file.ts 71 | ├───map-property-single-values-to-property-set.ts 72 | └───map-property-sets-to-generic-entities.ts 73 | ``` 74 | 75 | ### Getting started 76 | 77 | - A `config` object is created. 78 | 79 | The main repository uses a [config file](https://github.com/andrewisen/bim-whale/blob/b8427d3/src/config/example.config.ts). 80 | The public demo creates a [config object](https://github.com/andrewisen/bim-whale-demo/blob/main/public/assets/js/handle-ifc-file.js) inside the function. 81 | 82 | Both approaches are valid. 83 | 84 | - A new `IfcFile` object is created 85 | 86 | ```javascript 87 | let ifcFile = new BIMWHALE.IfcFile(lines, config); 88 | ``` 89 | 90 | The class `IfcFile` is an extension of the class `StepFile`. 91 | In other words, the `IfcFile`'s constructor is inherited from the [StepFile's constructor](https://github.bimvalen.se/docs/classes/stepfile.html#constructor). 92 | 93 | - The `IfcFile object` parse an IFC file and return `Property Sets` for each object (IFC Entity) 94 | 95 | ### In more detail 96 | 97 | 1. A `config object` is provided 98 | 2. A new [IfcFile object](https://github.bimvalen.se/docs/classes/ifcfile.html) is created 99 | 3. The [constructor](https://github.bimvalen.se/docs/classes/stepfile.html#constructor) handle the aforementioned `config object` 100 | 4. [parseStepFile()](https://github.bimvalen.se/docs/globals.html#_parsestepfile) iterates over **each line** and calls [generateStepInstance()](https://github.bimvalen.se/docs/globals.html#_generatestepinstance) 101 | 5. [generateStepInstance()](https://github.bimvalen.se/docs/globals.html#_generatestepinstance) generates a so-called `STEP Instance` object 102 | 103 | In this particular case, a `STEP Instance` object is one of the following 104 | 105 | - [IfcPropertySet](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifckernel/lexical/ifcpropertyset.htm) 106 | - [IfcPropertySingleValue](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifcpropertyresource/lexical/ifcpropertysinglevalue.htm) 107 | - [IfcRelDefinesByProperties](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifckernel/lexical/ifcreldefinesbyproperties.htm) 108 | - [IfcBuildingElement](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/FINAL/HTML/ifcproductextension/lexical/ifcbuildingelement.htm), which is denoted as a `genericEntity` 109 | 110 | 6. [parsestepinstanceattributes()](https://github.bimvalen.se/docs/globals.html#_parsestepinstanceattributes) is used to aid the aforementioned `generateStepInstance()`. 111 | 7. [mapPropertySingleValuesToPropertySet()](https://github.bimvalen.se/docs/classes/ifcfile.html#mappropertysinglevaluestopropertyset) maps a [IfcPropertySingleValue](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifcpropertyresource/lexical/ifcpropertysinglevalue.htm) to a [IfcPropertySet](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifckernel/lexical/ifcpropertyset.htm) 112 | 8. [mapPropertySetsToGenericEntities()](https://github.bimvalen.se/docs/classes/ifcfile.html#mappropertysetstogenericentities) maps a [IfcPropertySet](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifckernel/lexical/ifcpropertyset.htm) to a [IfcBuildingElement/GenericEntity](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/FINAL/HTML/ifcproductextension/lexical/ifcbuildingelement.htm) using an [objectified relationship (IfcRelDefinesByProperties)](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifckernel/lexical/ifcreldefinesbyproperties.htm) 113 | 114 | ### Why TypeScript? 115 | 116 | I prefer TS for one simple reason: 117 | 118 | > Developer tooling support / Enhanced IDE support 119 | 120 | See: [TypeScript in 100 Seconds](https://www.youtube.com/watch?v=zQnBQ4tB3ZA) 121 | 122 | In my option, TS makes it much easier to work with IFC. 123 | 124 | ### A word about performance 125 | 126 | - Avoid unwanted loops 127 | - Avoid nested loops 128 | - Avoid using try-catch-finally 129 | - Set correct variable scope 130 | - Use modern ES6 features (e.g. Object Destructuring, Spread Operator, template literals) 131 | 132 | **TODO** 133 | 134 | ## Where should I start? 135 | 136 | Start by looking at the [stepFile Class](https://github.bimvalen.se/docs/classes/stepfile.html). 137 | This is the base and deals with [STEP / ISO 10303](https://en.wikipedia.org/wiki/ISO_10303). 138 | 139 | In other words: 140 | 141 | - The [stepFile Class](https://github.bimvalen.se/docs/classes/stepfile.html) handles the parsing of a [STEP file](https://en.wikipedia.org/wiki/ISO_10303-21). 142 | - The [IfcFile Class](https://github.bimvalen.se/docs/classes/ifcfile.html) builds the relationship between objects (IFC Entites) according to the [IFC Schema](https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/). 143 | 144 | ### Example 145 | 146 | Let's take a look at the example file [SimpleWall](https://github.com/andrewisen/bim-whale-ifc-samples/tree/main/SimpleWall/IFC). 147 | Here's an extract of the file: 148 | 149 | ```javascript 150 | #297= IFCPROPERTYSINGLEVALUE('Description',$,IFCTEXT('_DESCRIPTION_'),$); 151 | #298= IFCPROPERTYSINGLEVALUE('Fire Rating',$,IFCTEXT('_FIRE-RATING_'),$); 152 | #299= IFCPROPERTYSINGLEVALUE('Keynote',$,IFCTEXT('_KEYNOTE_'),$); 153 | #300= IFCPROPERTYSINGLEVALUE('Manufacturer',$,IFCTEXT('_MANUFACTURER_'),$); 154 | #301= IFCPROPERTYSINGLEVALUE('Model',$,IFCTEXT('MODEL'),$); 155 | #302= IFCPROPERTYSINGLEVALUE('Type Comments',$,IFCTEXT('_TYPE-COMMENTS_'),$); 156 | #303= IFCPROPERTYSINGLEVALUE('Type Mark',$,IFCTEXT('_TYPE-MARK_'),$); 157 | #304= IFCPROPERTYSINGLEVALUE('Type Name',$,IFCTEXT('Bearing Wall'),$); 158 | #305= IFCPROPERTYSINGLEVALUE('URL',$,IFCTEXT('_URL_'),$); 159 | #306= IFCPROPERTYSINGLEVALUE('Family Name',$,IFCTEXT('Basic Wall'),$); 160 | ``` 161 | 162 | Each line consist of an **entity instance**. 163 | This can simply be referred to as an _entity_ or an _instance_ ("entity instance" is a long word). 164 | 165 | Each line contains the following: 166 | 167 | - Instance name 168 | - Entity name 169 | - Attributes 170 | 171 | Let's examine the **first line** in the example above: 172 | 173 | - Instance name: `#294` 174 | - Entity name: `IFCPROPERTYSINGLEVALUE` 175 | - Attributes: `'Description',$,IFCTEXT('_DESCRIPTION_'),$` 176 | 177 | The terminology above will be used throughout this site. 178 | 179 | The method [generateStepInstance()](https://github.bimvalen.se/docs/globals.html#_generatestepinstance) is used to build an **entity instance**. 180 | 181 | In other words: [stepFile Class](https://github.bimvalen.se/docs/classes/stepfile.html) will use [generateStepInstance()](https://github.bimvalen.se/docs/globals.html#_generatestepinstance) to generate each IFC Entity. 182 | 183 | **MORE INFO WILL COME** 184 | 185 | ## But, I don't understand 186 | 187 | No worries. The goal with The BIM Whale is to teach people how to work with IFC. 188 | However, the learning resources are not ready yet.
