BIM Underlay

()

Keyboard: BIMATTACH, IFCATTACH, RVTATTACH

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.

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.

After you attach a BIM underlay to the drawing, note the following:

Layers Use the BIM Properties pane to control visibility of layers in .ifc underlays and floors or categories in .ifc and .rvt underlays.
Entity snaps To snap to BIM underlays, turn the UOSNAP system variable on (or RVTOSNAP for only .rvt and .rfa files, or IFCOSNAP for only .ifc files). You can also control snapping to BIM underlays using the Options > Drafting tab.
Explode 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.
Unload and reload You can unload BIM underlays from the drawing and reload them to update the drawing with any changes made to the source file. Using the Explore External References command, right-click the underlay and choose Unload or Reload.
