Can you make a hole in a face?

[asteronimo]

hello,

I have just recently started to use SU for designing 3d models.
I cut them up into 2d slices that I can cut from mdf or plexiglas with my lasercutter.
I using the slicing script by TIG to do that.

However, before I export the them I want to make some rectangular holes in the slices.
Is there a way to do that with ruby?

TIA,

asteronimo

If you could make the holes before you slice up your model it would be a fairly simple thing, using the rectangle tool and push pull.

If doing it before the slice isnt an option you might want to check out the boolean scripts (a free one from oscar on here and a paying one from whaat that can be found on smustard.)

I agree with remus it is pretty simple using triangle and push/pull tool here is and example how to create one

• my apology, if you want rectangular simply create a rectangular (rectangular or offset tool) instead of triangle and proceed with the same step

neng83,

thnx for the example but i want to do it with a ruby script.

i found a short example that suggests to draw a polygon, add it to a group,
draw the rectangular hole, add it to the same group, execute the erase_enties
command on the group with the hole and then explode the group.
that seems to work!

that also works if you want to make more than 1 hole in a polygon.
