when you mean view I take it you mean a split screen different viewport. I recall a function called follow that would center the current viewport on another viewport. I don't have it here - hopefully I can find it in archives at home. but the code in it sounds like a starting point to make what you are looking for.
Cool, thanks.
Maybe I can flesh out what I mean a little better (hey bear with me, I'm a Texan, English is a foreign language fer me.)
TILEMODE=1
two viewports split vertically
Left viewport has a plan view of a structure
Right viewport viewpoint doesn't matter
I want to pick two points in the lefthand viewport:
One for TARGET
And one for angle of CAMERA from TARGET
Then enter the depth of the slice.
;;;;;;;;;;;I've got everything above this working
Then I want to select the RIGHTHAND viewport to display the slice. That's where I'm lost. In lisp, I don't know how to select another viewport to make it current.
I don't want to depend on preset CVPORT numbers because the next guy may have 4 viewports with the primary being an elevation from which he wants to cut plans.
Clear as mud, right?
