Objective:
Learn how to extract bodies from imported CAD for use in workflows.
Applies to:
- CAD Parts
- CAD Assemblies
- nTop 3.30+
Procedure:
Note: The examples below utilize our "CAD View" feature that was implemented in nTop 4.21. This feature is just for convenience and is not a necessity. If you are on an older version of nTop, skip Step 2.
Extraction by Properties:
1. Open up the Properties Panel for the imported part
2. Use the "CAD View" checkbox to isolate the CAD bodies list
3. Use the drop-down arrow next to the bodies list to show the items in the list.
4. Drag out the single body property chip
Common Mistake: Using the CAD Body List
We commonly see users experiencing issues downstream in their workflow where they can't insert a variable into an input. This is usually due to the variable being a list. Please ensure that the original CAD body that you extracted is a single body and not a list.
Extraction by manual selection on screen:
To extract CAD Faces:
-
- Single: Click on the face you want to extract
- Multiple: Hold SHIFT or CTRL and click on the faces you want to select
- R-click and choose the option "Create CAD Face Variable" or "Create CAD Face List Variable" if multiple selected
To extract CAD edges or vertices:
-
- Single: Click on the edge or vertex you want to extract
- Multiple: Hold SHIFT or CTRL and click on the edges or vertices you want to select
- R-click and choose the option "Create CAD Vertex Variable" or "Create CAD Edge Variable."
To create an Implicit Body or CAD Body:
-
- Single: Double click on the body (or just select a face on the same body if converting to Implicit)
- Multiple: Hold SHIFT or CTRL and double-click on the bodies you want (or choose just a face on the same body if converting to Implicit)
- Implicit: Right-click and choose "Convert CAD Body to Implicit Body" or "Convert CAD Bodies to Implicit Bodies."
- CAD: Right-click and select the option "Create CAD Body Variable" or "Create CAD Body List Variable."
And that's it! You've successfully extracted parts from your imported CAD Body for other workflows.
