Interference Detection PropertyManager

You can select components to check and set options for types of interferences to find, and then calculate the results.

You can use interference detection on assemblies opened in Large Design Review mode.
In Large Design Review mode, the volume of interference is not available and calculations for interference detection are approximate. Some options are not available. For accurate results, resolve the components and recalculate the interferences.

False positives in interference detection can occur when curved geometries are coincident or close enough to cause facets to collide.

To open this PropertyManager:

Click Interference Detection (Assembly toolbar) or Tools > Evaluate > Interference Detection.

Selected Components

Components to Check Displays components selected for the interference check. By default, the top-level assembly appears unless you preselect other components. When you check an assembly for interference, all of its components are checked. If you select a single component, only the interferences that involve that component are reported. If you select two or more components, only the interferences between the selected components are reported.
Calculate Checks for interferences.

Click Cancel in the dialog box or press ESC to cancel the calculations.

Excluded Components

Select Excluded Components to activate this group of commands.

Components to Exclude Lists the components that you select to exclude.
Hide excluded components from view Hides the selected components until you close the PropertyManager.

Not available in Large Design Review mode.
Remember excluded components Saves the list of components, so that they are automatically selected the next time you open the PropertyManager.

Not available in Large Design Review mode.

Results

Displays the detected interferences. The volume of each interference appears to the right of each listing. When you select an interference under Results, it highlights in red in the graphics area.

Right-click an interference for additional options including: Ignore all smaller than, Isolate when done, Sort Largest to Smallest, and Sort Smallest to Largest.

Ignore all smaller than, Sort Largest to Smallest, and Sort Smallest to Largest are not available in Large Design Review mode.
Ignore/Un-Ignore Click to switch between ignored and unignored mode for the selected interference. If an interference is set to Ignore, it remains ignored during subsequent interference calculations. See Show ignored interferences under Options.
Save Results Saves the results for interference detection to a Microsoft® Excel® spreadsheet. In the Save As dialog box, click Thumbnails to include an image of the interference.

Available for assemblies.
Component view Displays the interferences by component name instead of interference number.

Options

Treat coincidence as interference Reports coincident entities as interferences.

Not available in Large Design Review mode.
Show ignored interferences Displays ignored interferences in the Results list, with a gray icon.
Treat subassemblies as components Views subassemblies as single components so interferences between a subassembly's components are not reported.
Include multibody part interferences Reports interferences between bodies within multibody parts.
Include surface bodies Reports interferences between surface bodies. Surface interferences appear at the end of the results list.

The volume of interference is not available for surface body interferences.

Not available in Large Design Review mode.
Make interfering parts transparent Displays the components of the selected interference in transparent mode.
Create fasteners folder Under Results, segregates interferences between fasteners (such as a nut and bolt) into a separate folder named Fasteners. See Interference Detection with Fasteners.

Not available in Large Design Review mode.
Create matching cosmetic threads folder Under Results, segregates interferences between components with properly matched cosmetic threads into a separate folder named Matching cosmetic threads.

Interferences because of mismatched threads, misaligned threads, or other interfering geometry are listed as interferences.

Not available in Large Design Review mode.
Ignore hidden bodies/components Excludes the following interferences from the results:
  • Interferences involving components that are hidden, including those hidden by the Isolate command.
  • Interferences between a multibody part's hidden bodies and other components.

Not available in Large Design Review mode.
