fast workflow to create walls with MEP openings

[bernd]

you could create all walls quite normally without these breakthroughs.

but mostly nearly all walls have some breakthroughs, thus I search for something simple and fast


modern building have hundreds of breakthrough

i can imagine that it is relatively easy to program another type of window with the function break-through

[thomas-neemann]

is that a possibility for you?

(breakthroughs in arch wall)

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

Moving an object that is attached does not make a lot of sense...

To avoid cyclic dependencies and the TNP you should attach the "holes" sketch to the base of the wall, not to a face of the wall.

... Ultimately you would want a pipe etc. to create its own parametric hole...

May be in the future if we really would work on one modell in the cloud. But ATM the MEP engineers have it's own modell of the pipes in his own software and passes the breakthroughs to us. I am the structural engineer.

This is quite cools. I learnt there is a symmetric extrusion. Never knew there is . Very useful. In the wall "Move with host" needs to be active. Afterwards moving and rotating of the wall is possible and the holes will come with the wall. The tree looks clean too.

Just one point, would it be possible to give a step by step how to attach the sketch to the trace even if the trace is in a angle direction?

One disadvantage. If the wall is make visible the sketch is not anymore. To have both only woks for me in wire mode.

But these holes are independent/linked to the walls. It should be more logic if they are linked to a duct network (water pipes or climatic system). Therefore you should be able to substract the ducts from the walls in the clash points to create this system of holes. Maybe you can create groups of walls and substract the ducts from them with Boolean operations.

I do not know the diameter of the pipes. I do not know if the pipes have insulation. I do no know how much air needs bo be around the pipes. I do know nothing about the pipes. I get the holes from the MEP engineer, nothing more. That is the workflow ATM.

This may change in the future ... But ATM I will modell the holes. Thus I look for a smart fast parametric workflow.

Only one differnce ... In some projects I get the holes as ifc. They can be used directly. This works well already by the use of the minus tool. It is important to have holes 1 cm more width than the wall or slab. Thus there are no boolean problems. The software which is used by most MEP in swiss is able to add this 1 cm on the two side of the hole.

The angle of the Wall trace does not matter for the work flow, but the start and endpoint of the trace do have an impact on the mapping of course.

1. Create an Arch_Wall by clicking two points.
2. Since the wall trace is a sketch with a single line there is no need to make the sketch visible.
3. Create an empty "Hole" sketch.
4. Click in the Map Mode field of the "hole" sketch and press the "..." button.
5. Select the Wall trace in the tree.
6. Add ":Edge1" to the first field in the task panel.
7. Change the "Around y-axis" field to 90°.
8. Press "OK".
9. Edit the "Hole" sketch.
10. Part_Extrude the holes.
11. Arch_Remove the holes from the wall.

You can copy-paste a "Hole" sketch with its holes (but without the wall trace). Once copied change the "Support" property of the new "Hole" sketch to reference a different wall trace, change the sketch, and Arch_Remove.
