Opening: cut through wall model, but not cut wall in plan

TomWaltz — Wed, 24 May 2023 10:12:21 GMT

I am trying to create an object of a through-wall heater/air conditioner commonly used on our projects.

This unit usually sits below a window. It needs to look like a box with louvers on the outside, which cuts through the wall.

I got the geometry of the unit correct in 3D. by making it a "window," it cuts through the wall and locates the outside grill correctly.

My only problem is in the 2D window. I really only want the inside "box" part of the unit to show. I don't want the window to break, since it is usually wider than the window it sits under, making a very odd-looking plan view.

Is there a way to get a Window (or Door) to NOT break the wall in plan view?

I've tried every option for Wallhole I can think of, and am out of ideas!

Just an idea - it's a workaround, but...

Create a new wall, and put the object in the new wall. Reduce all of the new wall's dimensions such that they are less than the object, finally ensure that the wall is thinner than the wall containing the window.

Position the new wall and its object where you want. AFAIK this will achieve the effect that you are after - i.e ho hole visible in plan. Of course if don't want to see the object in plan, put the wall on a layer that won't appear in your 2D view but will be visible in the 3d view. To avoid problems ensure that this layer has a unique intersection number.

I can't guarantee that this will work, but it's probably worth a try.

Tom,
For 3D script, you can rotate the walhole or wallniche and then move it, so it will never cross the wall.
Something like
ADDz WALL_THICKNESS (or any other value)
ROTy -90
I suppose this is what you did.

For 2D Script
In the parameters windows, check the Details button, in X+ offset, type -A/2, and the same for X- offset
This way the 2D symbol will never show in plan the cutted part of the window.

Not sure if i i understood you correctly.

Tom,
If I understand your problem correctly, it is very similar
to the problem of inserting high windows in a wall and not having
the 2d wall opening show in plan. There is a thread on this issue. Unfortunately I don't know a search key word to find that thread.

The problem is a 2D issue and does not concern Wallhole.
There are several approaches to the problem.

One, in the 2D script make a fill to mask the 2D wall opening with
a boolean switch to enable it.

Two, make the left and right "over size" in the "details" pane negative
and equal to one half the opening size with a boolean switch to enable it .

Three, manually draw a masking fill in plan to fill the window opening
and adjust the drawing order to make the air conditioner show and
the opening and window be behind the object.

There are other approaches to this problem. The above are ones
that come to mind.

HTH,
Peter Devlin

in X+ offset, type -A/2,

That was EXACTLY the point I needed to make this all work.

Thanks for the help!!!
