Interference Detection
In a complex assembly, it can be difficult to visually determine whether
components interfere with each other. With Interference
Detection, you can:
Determine
the interference between components.
Display
the true volume of interference as a shaded volume.
Change
the display settings of the interfering and non-interfering components
to see the interference better.
Select
to ignore interferences that you want to exclude, such as press fits,
interferences of threaded fasteners, and so on.
Choose
to include interferences between bodies within a multibody part.
Choose
to treat a sub-assembly as a single component, so that interferences between
the sub-assembly's components are not reported.
Distinguish
between coincidence interferences and standard interferences.
To check for interferences in
an assembly:
Click Interference Detection 
(Assembly toolbar) or Tools,
Interference Detection.
Set options
and settings described below in the PropertyManager.
Under Selected Components, click Calculate.
The detected interferences are listed under Results.
The volume of each interference appears to the right of each listing.
Under Results, you can:
Select
an interference to highlight it in red in the graphics area.
Expand
interferences to display the names of the interfering components.
Right-click
an interference and select Zoom to selection,
to zoom to the interfering components in the graphics area.
Right-click
an interference and select Ignore.
Right-click
an ignored interference and select Un-Ignore.
Selected Components
Components to Check. Displays components
selected for the interference check. By default, the top-level assembly
appears unless you pre-select 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. Click to check for interferences.
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.
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.
Component
view. Displays the interferences by component name instead of interference
number.
Options
Treat
coincidence as interference. Reports coincident entities as interferences.
Show
ignored interferences. Select to show ignored interferences in
the Results list, with a gray
icon. When this option is cleared, ignored interferences are not listed.
Treat
subassemblies as components. When selected, sub-assemblies are
treated as single components, so interferences between a sub-assembly's
components are not reported.
Include
multibody part interferences. Select to report interferences between
bodies within multibody parts.
Make
interfering parts transparent. Select to display the components
of the selected interference in transparent mode.
Create
fasteners folder. Segregates interferences between fasteners (such
as a nut and bolt) into a separate folder under Results.
See Interference
Detection with Fasteners.
Non-interfering Components.
Displays non-interfering components
in the selected mode:
