This module will draw a 2D plan drawing from a geoJSON object. It was built to visualize 2D space boundaries from the Building Information Modeling (BIM) authring tool, Revit. It is quite generic, but does have some features that are mainly related to the work done by the W3C Linked Building Data (LBD) Community Group.

The implementation I personally use is the following:

1. Export BOT triples from Revit using Revit-bot-exporter
2. Export 2D space boundaries to WKT polygons using Dynamo script
3. Merge WKT polygons and relevant information to geoJSON using the wellknown library
4. Send resulting geoJSON object to Ng-Plan for visualization

Install package npm i ng-plan --save

Add to app.module.ts

import { PlanModule } from 'ng-plan';

@NgModule({
  imports: [
    ...,
    PlanModule
  ]
})

Now Ng-plan can be used anywhere using the tag.

<ng-plan [data]="data">
</ng-plan>

where data is the geoJSON data.

The Ng-plan toolbar uses material icons, so the following must be added to index.html for the toolbar to display correctly: <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
