Been fighting with my drafting software Survey 14 and run into
issues with the TRIM command not functioning
for reasons I cannot figure out.
To get around TRIM not working, I sometime must add
extra line segments at apparent intersections and use
those to get the subject lines trimmed.
I suspect there is a setting somewhere that is
giving weight to elevation differences and that is
why TRIM doesn't see the intersections.
Right now I am dealing with re-contouring a portion
of an old drawing, and I am trying to wipe out the
old contours (only inside a remapped area).
I have had luck with TRIM on all but one pesky contour, and
have tried my fall back of adding small lines where I want the
break to occur, but am having no luck.
I don't know why this one contour is refusing to die inside my
remapped area, as all the other contours broke where they were told.
Any thoughts?
EXPLODE just worked as my temporary solution,
but I am still looking for an answer for my
regularly occurring TRIM refusals.
Thanks
I am not on the Intellicad version, but is the "trim" function the same as the surface merge routine in the embedded version, or are you actually trimming the triangles and adding new faces by hand??
See if the "Projection" option is set to None:
>Command: trim
>Select cutting entities for trim :
>Entities in set: 1
>Select cutting entities for trim :
>Edge mode/Fence/Projection/Undo/:
You'd probably want to set it to UCS. Otherwise, it'd be helpful to know what the entity was prior to the aforementioned Explode command. You might also explore the EDGEMODE variable:
>Controls the cutting and boundary edge settings for the TRIM and EXTEND commands. When off (0), you trim and extend entities using selected edges. When on (1), you can trim and extend entities to extensions of selected edges.
Other option would be to explore the Edit -- Erase by Closed Polyline command as an alternative to TRIM.
