This section describes the options available in the 3D-BIM group in the Design Master HVAC Options dialog box.
3D circle approximation: Circles are approximated in the 3D model as polygons. This option sets the number of sides of a polygon used to represent a circle. Higher numbers more closely approximate a circle, but greatly increase file size. The minimum number value for this option is 8.
Draw hangers in 3D: Whether hangers are drawn in 3D. This setting has no impact on exporting hangers to an IFC file. It only affects whether they are visible in your CAD program.
Draw mechanical equipment in 3D: Whether mechanical equipment is drawn in 3D.This setting has no impact on exporting mechanical equipment to an IFC file. It only affects whether they are visible in your CAD program.
Export flex duct: Whether flex ducts are exported.
Export diffusers: Which diffusers are exported.
| • | All: All diffusers will be exported. |
| • | Ceiling only: Only ceiling diffusers will be exported. |
| • | Sidewall only: Only sidewall diffusers will be exported. |
| • | Connected to hard ducts: Only diffusers connected using hard ducts will be exported. See the Change Connection Type section for more information. |
| • | None: No diffusers will be exported. |
