Add Wipeout to Perimeter of Block LISP

[anderson51]

Is there a way to add a wipeout to the perimeter of a block without have to draw a polyline?

Thanks,

Anderson

Probably best to post your block. Also there is a wealth of information to programmatically add wipeouts HERE.

I am talking Blocks in general.

Thanks, Ill check out the link.

Sounds good. Have you considered using a solid hatch with color 255,255,255 instead? I setup all my blocks many moons ago like this and it's worked great. :clinking_beer_mugs:

Im not sure Im following what you mean, can you post an example of how it turns out?

Thanks,

[ronjonp]

Sure. The truecolor white prints white so it will hide objects behind it.

A new question are you talking an individual block or all blocks of that name. Doing boundaries can be a bit hit miss.

@anderson51 when @ronjonp  ask you to upload a sample , you say GENERAL BLOCK , and then you ask @ronjonp  to upload a sample.

Reciprocation is good a way to behave.

Individual blocks

Ive never attempted to use the boundary command, Ill have to check it out.

Thanks.

I like that idea, never thought of doing that before.

Thanks for the input!

@anderson51 Glad to help! :clinking_beer_mugs: One nice thing about the hatch is you can create it from many different boundaries where wipeouts need straight segment boundaries. I Changed to these when I was having issues with the wipeouts printing black on plans ... but that was over 10 years ago.

Using the Bounding box function in vl is the simplest this will give a box around the block based on x y, in saying that it is possible to get the same for a rotated block where the box is to be on an angle. If the block needs a different shape it becomes way harder.

"way harder" is an understatement.  One can not find the irregular limits of a block even by ray-casting and getboundingbox and intersectwith methods because the bounding box is always just a rectangle encompassing the outer limits of the block.  Same is true for mtext.  It would be better to manually add either the wipeout or white-out to the block definition.  Just draw a polyline around the visual limits on a unique layer, say "WIPEOUT" and fill it using the preferred method.  I prefer using wipeouts.
