cutting in 3D

hi all,
whats the best command to use when trying to cut one object with another,
where the point at which they join is a bit too complex to use 'slice'? I
have had good success using 'subtract' but then one of my solids is gone.
is there a similar command that will slice one solid where it meets a second
solid, but leave them as seperate entities?

Thanks,
Shaun

 

Continue to use subtract - just make a copy of the object and subtract a
solid from both sides of the cut line, one then the other copy.

you can do many slices, keeping both sides of the slices, then erase what
you wish & union the rest back together!

 

INTERFERENCE

This create a THIRD composite 3D solid from the common volume of two or more solids.

Ive had a bit of a go at the various methods suggested, but the best i can
come up with so far is still to subtract. what i do is make a copy of the
object i will subtract, move it, say 500 away in the x plane for example,
then subtract, then move the caopy bak in to take the place of the solid
that was lost by subtraction. This works, but like most of my cad work, its
not elegant in the least!

Thanks all,
Shaun

 

Eliminate a couple of steps by not moving the copy -- just subtract the
original and the copy is right there. Here is a brief LISP I use to copy
things in place:


(defun c:c0 () ;copy in place -- that's C-ZERO, not C-OH
(prompt "Select objects to copy @0,0: ")
(command "select" pause)
(command "copy" "p" "" "0,0" "0,0")
)
