BIM Underlay

()

Keyboard: BIMATTACH

Attaches a Building Information Modeling (BIM) file as an underlay to the current drawing. You can attach .rvt, .rfa, and .ifc files as underlays, which is similar to attaching an image file. Note that .rvt and .rfa files can be attached in only 64-bit versions of the program.

After you attach a BIM underlay, note the following:

Layers Even though .ifc files do not contain layers, you can control visibility by enabling/disabling floors or categories using the BIM Properties pane. Use the BIMPANE command to open the BIM Properties pane (and use BIMPANECLOSE to close the pane).
Entity snapping BIM underlays support entity snapping if you enable snapping using the UOSNAP system variable (or RVTOSNAP for only .rvt and .rfa files or IFCOSNAP for only .ifc files). You can also use the Options command, Snapping tab.
Exploding The BIM Explode command breaks apart an attached BIM underlay into polyface meshes and polylines that can be edited. BIM Explode is similar to using the Explode command for a BIM underlay except all BIM underlay intelligence is kept intact and each resulting entity is placed on its own layer.

In the Select Reference File dialog box, select the desired .rvt, .rfa, or .ifc file.

Specify insertion point: Select an insertion point in the drawing.

Specify scale factor or [Unit] <1.0000> Enter the scale in which to insert the BIM file, then press Enter.

Specify rotation <0>: Enter the rotation to use for the insertion, then press Enter.
