To control the detail with which CAD models are displayed, and to specify the default offset and tolerance values for inspection, section, and geometric groups:
- Click Measure tab > Current panel > Parameters.
- In the Measure Parameters dialog, select the General tab.
- In the Units list, select the unit of measurement for the inspection document.
- Enter the default tolerance and offset values for new inspection groups:
- Surface offset specifies the offset of the part's surface from the CAD nominal.
- Surface point tolerance specifies the Low and High tolerances for probed surface points.
- Edge offset specifies the offset of the part's edge from the CAD nominal.
- Edge point tolerance specifies the Low and High tolerances for probed edge points.
A positive offset value indicates excess material on the part.
- When you display a model in a wireframe mode, each patch formed by the laterals and longitudinals of a surface is divided into a 2x2 mesh by default. To change the size of the mesh for all surfaces, enter new values in the U density and V density boxes. The larger the values, the more lines are shown in the U and V parameter ranges.
- If you want to hide the detail lines for
all
surfaces and show only the laterals and longitudinals of the model, deselect the
Display internal lines on surfaces check box.
To change the meshing for individual surfaces, use the Meshing Parameters dialog.
- In the
Default geometric group tolerances boxes, enter the tolerances to be used as the defaults when creating geometric groups. You can specify tolerances by typing a value into the
Low tol or
High tol boxes, or by clicking a
Define tolerance
button and selecting the values from the tolerance database.
- Select Save as default parameters if you want to use these values as the defaults for new inspections.
Note: You can override the defaults for any group by changing the values in the group's definition dialog.
