Recess in Wall (not an opening)

[harliY432P]

Hi All,

Is there a way (beside cut geometry) to create a recess in a wall? By recess I mean an opening that doesn't go all the way through, i.e. a step in the wall.

The cut geometry tool, from my limited experience, forces the user to draw the portion of the wall that must remain and not the "negative" part.

I'm looking for a solution similar to what a boolean subtraction would do, for example. One draws a wall (5m long x 3m high x 0.3m thick), one then draws a "negative" (the part to be removed), 1m long x 1m high x 0.1m thick). Click the host wall and then click the negative and then one is left with a wall that is 0.2m thick.

The cut tool seems to force the user to do the same as the above but draw in a 0.2m thick cutting portion that ends up being the left-over.

Thanks.

For the cut tool, it's important in which sequence you select the elements. 

FIRST Pick: Select elements to be cut OR host wall.

SECOND Pick: Select wall parallel to host OR family instance to cut with.

So that way, you can draw the negative, like you want to and cut it out of the wall you need. First select the wall, then select the negative and you end up with what you are trying to achieve.

Hi Jeroen,

Thanks for the suggestion. You'll see in my screencast below that the order of selection does not appear to be working.

I'm trying both orders in this screen cast. The first time the portion that is meant to be removed, ends up remaining. In the second time, the portion to be removed just disappears.

Any other ideas?

Thanks

Hi

You could try a 'model-in-place' and draw void extrusions and then cut the wall with those voids.

Since you want the form to 'disappear', a void is needed.

you can use the wall reveal tool.
