Grab a distance using the

tzframpton · 发表于 2022-7-7 00:13:26

I'm trying to see if I can't invoke a CAL expression transparently during a command (such as MOVE) and pick two points to calculate a distance. I've researched the CAL Topics [link here] and it seems there's a dist(p1,p2) command but it errors, so I'm guessing that has to do with LISP or some other type of information handling.

Anybody know of such a way? Thanks in advance.

Are you trying to move an object say ortho but picking two points that are not square ?

Move pick object pick two random pts works ? moves relative.

Are you looking at using the distance later ? a bit more info please.

Had a bit more of a play if you use lisp and create p1 p2 then dist works also if you do another move then type !p1 !p2 it will move object the pre defined distance and angle.

Something like this (clipped from command window)?

Command: m
MOVE
Select objects: Specify opposite corner: 0 found
Select objects: Specify opposite corner: 1 found
Select objects:
Specify base point or [Displacement] : cen of Specify second
point or : 'cal
>>>> Expression: (end+end)
>>>> Select entity for END snap:
>>>> Select entity for END snap:
Resuming MOVE command.
Specify second point or :
52.456918101139,13.513592022022,0

This was used to move a circle using it's center as a base point, and adding the endpoints of two lines together to get the distance.

correction---this process gives you the coordinates of your destination, not the distance
