Class Viewer2d

Destroys the viewer and any (heavy) resources associated with it. As long as there is a reference to the Viewer2d instance it won't be completely destroyed.

This method must be called before loading any of the models. Keep in mind that this method is async, and models can only be loaded after the returned Promise has resolved.

Will take a screenshot of the contents of the Viewer2d.

Example

The returned Blob can for example be downloaded by the user, using the following example

    const width = viewer2d.width;
    const height = viewer2d.height;
    const filename = `screencapture-${width}x${height}.png`;
    Utils.downloadBlob(blob, filename);

Returns

A Blob

To be called whenever the rendering state has changed and updates need to become visible

Starts the viewer. The viewer will only redraw when needed.

Stops the viewer. When the viewer is stopped, the view is not updated anymore. Any changes to the viewer will be accumulated and become visible as soon as the viewer is started again The main reason for stopping the viewer would be for performance, for example when the viewer is currently hidden

Toggle whether (generated) door openings are rendered. This only works for models that have been processed when the repository setting features.generate_door_openings had been enabled. Some models contains door opening direction geometry as IFC lines, in those cases it's best to disabled rendering generated door openings.

Toggle whether faces are rendered.

Toggle whether ifc lines are rendered. IFC Lines are all lines that have been defined in the original IFC file, such as Axis and FootPrint representations.

Toggles whether the text labels are shown

Toggle whether wireframes are rendered. Wireframes are usually drawn to emphesize the edges and generally make the model look better
