fast workflow to create walls with MEP openings

[bernd]

What is a fast workflow with Arch module to create concrete walls with a lot of small holes which are neither doors not windows but for MEP pipes? It should be parametric, means if the thickness of the wall will be changed they change too and if the wall is moved they move too.

Hello Bernd

i would create it with the sktetcher and part extrude

Greetings Thomas

But this has a problem. Change the width of the wall to 300 mm and the opening will no longer be all in the wall ...

I would just do it that way

Aha, might be powerful for just one wall, but not for a whole floor. Generally I make walls of a floor out of lines and the lines have a thickness and a height. Standard Arch wall object.

BTW: The wall missed some fixes against wind, when it was built. Thus it was falling down and is lying on the ground (xy-plane) ...

[thomas-neemann]

you could create all walls quite normally without these breakthroughs.

[bernd]

how about this:

- make the wall with Arch Wall based on a line
- make a sketch FlatFace
- move the sketch 500 mm i z direction (attachement attribute of the sketch)
- create as many holes as there are
- make a 1.0 m extrudion
- select the extrution afterwards the wall and klick the minus in Arch

- try to change thickness of the wall, after recomute all holes are there

open the file from the last post, use the Draft move tool ...
