Detect interferences and conditions of tangency between parts, then view detailed
results on where they occur in a motion analysis.
Prerequisite: Run a motion analysis.
To use Interference Detection:
Open the Review section on the Motion ribbon, then
select Interference Detection.
The guide bar appears.
Select parts for Parts 1.
Note:
If you only use one set of parts (Parts 1),
the search will be performed between all parts in the set. If you
use two sets of parts, (Parts 1 and
Parts 2), the search will run between the
selected parts in opposing sets.
The parentheses next to Parts 1 and
Parts 2 display the number of parts
selected for each option.
To reset the part selection and restore the default guide
bar, click .
Optional: Select parts for Parts 2.
A filtering window appears.

Notes
View the number of frames used in the search
In the filtering window, next to
Frames, refer to the number in
parentheses.
Search all steps in the analysis for
interferences
In the filtering window, select Use all
samples.
Specify when to start and end the search
In the filtering window, select
Range, then enter values for
Start and
End.
Specify steps to skip over in the search
In the filtering window, select
Range, then enter a value for
Step.
Tip:
Setting a specific time range and
Step to skip over can help
speed up the detection process by not searching
redundant interferences.
Stop the search at the first detected
interference
In the filtering window, turn on Stop at
first.
View maximum interferences and display volume in the
Results Review window
In the filtering window, turn on Compute
volume.
Tip:
To speed up results, turn off Compute
volume.
Exclude interferences with volume values of 0 from your
search
In the filtering window, turn on Ignore 0
volume.
Tip:
Parts that have coincident (or tangent) faces will
return a 0 volume interference. The
Ignore 0 volume option can
be used to disregard all instances of coincident
faces.
Interferences involving parts that have 0 volume
(like sheet parts) will result in an interfering
volume of 0, even though it may be a legitimate
occurrence of interference. To see interferences
involving 0 volume parts, turn on Compute
volume.
In the guide bar, click to apply the filters and run the search.
