Can I trim or break on a circle?
Hi,
For my work I need to import city plans into bricscad. I only need a small circle of these plans, so i need to delete everything outside the circle. Now I ask my colleague who uses autocad to extrim on a circle and afterwords I use select outside circle to select and delete everything outside the circle, but I need to be able to do this on my own. Is there any way to use a circle to break everything on that cirle or is there any other way to do this?
Thank you.

Found this LISP somewhere been awhile since I used it.
Make a circle on the side the a circle around what you want scale if they are different size. Load then type magglass.
Pick the empty circle then the one you want to go from.

EXTRIM is part of Express Tools, in both AC and BC. For Bricscad, it's available at https://www.bricsys.com/applications/a/?express-tools-a589-al1002
Something that might suit your purpose better is CookieCutter2 v1.2.lsp, posted by Joe Burke at http://www.theswamp.org/index.php?topic=24646.0;all (scroll down, or search the page for v1.2). It includes an option to delete everything outside the circle, not just things that are cut by the circle.

C2GON.lsp from here might be helpful to make a circle into a polygon.

You could leave the intact larger area as an XREF and use a circular polygon boundary to XCLIP it.

Roy has a routine that might be what you are looking for:
(http://www.b-k-g.nl/bkg_extrim.html "b-k-g.nl/bkg_extrim.html")
It might be easier to load this than Express Tools which I never did get to work.
