SDX-Cloud: IFC support for reference models

TL;DR: Import an IFC model on Data > Reference models with Add. Set its unit to Meter, Feet, or US survey feet, and make sure it is in project coordinates. You can then view it, measure on it, and compare against it.

Import an IFC model

IFC works for reference models only. On Data models, an IFC file is marked with an error and the import cannot continue.

Open your project and go to Data > Reference models.
Select Add. The Create reference model window opens.
Enter a Name.
Drag the IFC file into the Drop Zone, from the file explorer or from your computer.
Set the unit next to the file: Meter, Feet, or US survey feet.
Check the Gradient and Z-axis displacement. See SDX-Cloud: Reference models.
Select Create.

One file per reference model

A reference model holds one file. The Drop Zone shows "Drop another file to replace it": dropping a second file replaces the first. To remove the file, select the minus button next to it.

File requirements

The IFC model must be in the project coordinate system. SDX-Cloud does not use embedded georeferencing to move it.
The file units must be meters, feet, or US survey feet. Millimeters are not converted automatically, and the unit list has no millimeter option. Export the model in meters if it is in millimeters.

What you can do with an IFC model

Show it in the 3D viewer: View > Layers > Reference models, then the eye button of Model.
Measure on it with Measure in the viewer.
Use it as a comparison target: turn on Comparison for the model in the same list.

Control single objects

Turn single objects on and off.
Set a color for each object.
Read the properties of an object. Objects are listed in a structured list.

Visibility and color changes apply only to you and only for the current session. They are not saved and not shared.

IFC and comparisons

For comparisons, SDX-Cloud converts all IFC objects into one surface. Hiding objects does not change this.

Some IFC files do not make a useful surface. If a file holds several objects, including objects stacked on top of each other, do not use it for comparisons.
