Clearance Verification

Finds pairs of parts that sit closer than a gap you choose. Assemblies need the Pro plan.

When to Use It

• Check a minimum gap, for example 1/16 in, between moving parts
• Find parts that are almost touching
• Save a list of tight spots

Step by Step

1. Open the assembly.
2. Click Clearance on the Assembly tab (Evaluate group). The window opens.
3. Choose the components in the list as in Interference Detection (all ticked to begin).
4. Type the Minimum acceptable clearance. It starts at 2 mm in the model's units. Fractions such as 1/16 are accepted.
5. Click Calculate. The results pair the parts that sit closer than the minimum.
6. Click a result to see the pair in the view.
7. Click Save results for a CSV file.
8. Close the window with the X or Esc.

Options

• Ignore clearances equal to the minimum: leaves out pairs that are exactly at the gap.
• Include hidden components: also checks parts you have hidden (off to begin).

Tips and What to Expect

• Parts that overlap are an interference, not a clearance; use Interference Detection for those.
• Results are not saved with the assembly.
• For a live check while you drag a part, use Dynamic Clearance in Move Component.

Common Problems

• "Press Calculate." Nothing has been run yet.
• A result list that looks wrong after an edit. Press Calculate again; the list is for the last run.
