How to clip a block with a circle?

[Anonymous]

Hi All,

I am trying to clip a block using circle, but I need the information outside the circle (it's actually multiple circles). Are there any command that I can use other than WIPEOUT ?

Thanks,

Flora

EXTRIM may do what you want, unless you are trying to operate on multiple, different insertions of a block definition. 

If you want to use the traditional XCLIP command, then instead of drawing a true CIRCLE, use the POLYGON command to draw a polygon with say, 200 sides, and use that for your cutting edge. Be sure to invoke the "Invert Clip" option.

Hatch with pattern = SOLID and a true-color of 255,255,255 (to make sure it's white when plotted, independent of CTB).

Hello @florawa, 

Taking into account that you do not want to modify your block but if you use a part of it since you may need it in the same file with its original appearance, I will show you XCLIP and the variable XCLIPFRAME.

XCLIP will allow you to start from an edge, delimit what you want from what you do not want to show, and with the variable XCLIPFRAME you control the edge.

XCLIP command

XCLIPFRAME (System Variable)

Watch the screencast.

Although you need a circle, I used a 48-sided polyline based on the circle to select it in the XCLIP command options.

Hi, @Anonymous

I found the solution see this Video. First Convert Circle to Polyline use .lsp Use command FLATTEN in circle polyline then XCLIP https://autode.sk/2LuapRR

Circle can convert to polyline using Donut inside diameter of donut outside diameter of donut and change width to 0 or draw a circle use boundary [BO] or .lip also available to convert Circle to polyline

Why not just use solution in post #2 of this thread? Use the polygon command, and set the number of sides to something like 200.

To be continue in post thread, i seen error message "Boundaries With Zero Area are Not Acceptable" you can also see video at .43 sec.

After post the forums i continue to find solution for error message "Boundaries With Zero Area are Not Acceptable"

Then i understand use FLATTEN Command. So i post next forum with Screencast.

Thanks

Looks useful for other problems, but unfortunately I want the things inside circle to be hidden. 

Many thanks though!

That's great that you clarified that @jayhar didn't understand the question but what about the other posters that did understand and offered viable solutions?
