Find areas where 3D
solids or surfaces intersect or overlap.
Use
the INTERFERE command to check
for areas of interference within a set of 3D solid or surface models.
You can compare two sets of objects or check all 3D solids and surfaces
in a drawing.
Interference checking
creates temporary solid or surface objects and highlights where
the models intersect.
If the selection set
contains both 3D solids and surfaces, the resulting interference
object is a surface.
You cannot check interference
for mesh objects. However, if you select mesh objects, you can choose
to convert them to a solid or surface object and continue the operation.
During the checking operation,
you can use the Interference
Checking dialog box to cycle through and
zoom to interference objects. You can also specify whether to delete
the temporary objects that are created during interference checking.
Methods for Checking Interference
You can check interference
using the following methods:
- Define one selection set. Check
the interference of all the 3D solids and surfaces in a single selection
set.
- Define two selection sets. Check
the interference of the objects in the first set of objects against
the objects in the second selection set.
- Individually specify solids
that are nested within blocks or xrefs. Individually
select 3D solid or surface objects that are nested in blocks and
external references (xrefs) and compare them against other objects
in the selection set.
To check for interferences
within a solid model
- Select the first set
of 3D solids and surfaces in the model. Press Enter.
- Select the second set
of 3D solids and surfaces in the model. Press Enter.
The
Interference Checking dialog box is displayed. The areas of interference
are displayed as new, highlighted solid objects.
- To cycle through the
interference objects, in the Interference Checking dialog box, click
Next and Previous.
- To retain the new interference
objects after you close the Interference Checking dialog box, clear
Delete Interference Objects Created on Close.
- Click Close.
If Delete Interference Objects on Close is selected,
the new interference objects are deleted.
To change the display of
interference objects
- Enter s (Settings).
Press Enter.
- In the Interference
Settings dialog box, change any of the settings and click OK.
