Menu : TRIM

Command: Intersect:Surface

Shortcut : None

This command computes the intersection between the target surface and another surface.

If the resulting intersection curves forms a closed area of the surface, that area is cut away from the surface. For the treatment of open intersections, see the command TRIMÞPreferences.

For this command, the target surface is called "this surface". The second surface is called "other surface".

Normally pointing and clicking with the left-hand mouse button after executing the command indicates the other surface. Sometimes it may be difficult to point exactly at the surface that you want. The alternative way is to click any key on the keyboard, which brings up a dialogue box into which the name of the element where the surface is located and the number of the surface is entered.

After the other surface has been indicated, the program computes the intersection, and makes a guess at the parts of the surface which are to be cut away, displaying the result on the screen. If the guess that DeskArtes has made is incorrect, the user can change the result for either surface, by inverting this or the other surface.

If you intersect a previously trimmed surface, the system automatically combines or merges the new trim curves with the old ones. The basic rule for the automatic combining of trimmings is that new trim commands always cut parts away of the old model, never adding anything. See the command TRIMÞChange:Merge Trim Sets for further discussion of this.
