Taper to circular window in wall - how can I model this without it changing from being a wall.

[mattfox]

Hi. I have an existing building with a series for porthole windows that have a splay to the reveal.

 

I can multiple extrude to create the splay, but don't want to subtract from the wall as this will turn the wall into a solid subtraction. I cannot see how to form a splay in the wall. Does anyone have any ideas?

 

Thanks

Create a symbol that includes the multiple extrude in the Wall Hole Component then insert it in the wall. Just include a 3D locus as the 3D component. Add geometry to the 2D component based on what you want to see in Top/Plan.

 

Make sure symbol has 'Insert in Walls' enabled.

Ahh. Thanks Tom. Good thinking. I'd not thought to do this... Very helpful.

Yes, and in addition to Tom's suggestion, another approach without the need to create a symbol,  is to utilize the option to 'create wall recess' in the AEC Menu options.

It too does a pretty Nice job 🙂

Ok, I forgot to mention, I created a tapered extrude instead of a multiple extrude...the shaded rendering option seemed to like that better 🙂

Thank you Kevin. I agree the rendered output from multiple extrude looks more faceted. Great to hear of two methods to solve this issue.

Actually @mattfox you asked about subtracting from the wall which is why I suggested a Wall Hole Cutter symbol but thinking about it this is probably best done as a circular Window object with Wall Closures:

Tom, that is a great solution for @mattfox since I am pretty sure he will need to have some glass within that opening.

Could you post a small file showing how you configured that opening etc. ??

Sure. Can't find the other file but here is another one... (VW2023)

Thanks Tom. 

I was thinking that this may be helpful to @mattfox to see the master at work 🙂

Perfect. Thank you both. I've just tried the Wall Closures as a trial and this seems to work very well indeed. Good to know there are multiple ways of doing this. Much appreciated.
