Hello
I'm drawing a wall section through a window, to show how it would be installed. Most things are either rectangles or at least axis-aligned polygons. I'd love the lines to be drawn slightly inset, so that they do not overlap. Right now, the "topmost" lines just hide the ones lower down.
Is there any way to achieve this? I'd prefer not to fully hash everything.
Thanks and greetings!

Hi,
is it possible for you to narrow the task down with a screenshot or dxf/dwg drawing? Thanks.

Attached is a dxf/screenshot. Every "part" is a rectangle, but due to them overlapping, you cannot see the colors everywhere. If the lines were drawn "inset" just a bit (the lines' width), everything would show up nicely.
Maybe I'm thinking too much in "objects" and not enough in CAD lines.. maybe the solution would be a special type of Hatching that only drew along the outlines, not actually the entire inside?

Thanks for clarification.

Ok, I see were you are going ...

You could use the offset tool but in CAD every entity has a purpose. Not sure how that would work for you.
You have also the possibility to bring entities in the front or the background. Menu/Modify/Draw Order but this has again limitation in your drawing situation.

I assume hatching is the way to go. If you are looking only to make a perimeter hatch then the Offset toll can help you again to limit the hatch.

Searched for an offset tolerance but didn't find it.
I think its a typo and then yes Offsetting is the message.

The difficulty is you can't offset a multi-selection to offset to all individually.
***correction*** not all kinds of entities individually ***correction***

The catch is that CAD allow us to draw things exactly at the same spot.
And that the lineweight is centered on the entity.
There is no information on inside or outside.
Using only contours its gets even harder to distinguish.
In real life those things we draw are not exactly occupying the same space at their boundaries.
That's the catch.

A nice solution would be a Face.

That is incorrect.

OK, Not All
