How can I create slanted walls in BlenderBIM?

Abhishek

Hello OSArch Community,

I'm working with the BlenderBIM Add-on and would like to create walls that are slanted (i.e., not vertical). Could someone please guide me on how to model a slant wall in BlenderBIM? Which tools or workflows are best for this?/
Thank you!

Got it thanks a lot @steverugi and how to do a tapered wall ?

@Abhishek
1. select your wall and hold Shift
2. select your slanted slab
3. click on Extend to Underside in the "Tool" panel on the right (use "N" to turn it on)

@Abhishek
Sorry the above is not a tapered wall
for that you I think you need a profile, will show it later if you like
however, for your information, the cutting of the wall above is performed by a boolean difference (press Tab to show it):

@Abhishek
for a tapered wall like a retaining wall :

create a section shape

1. go to top view and Add > Mesh > Plane
2. edit the plane to a shape like

create a profile

1. go to "Geometry and Materials" panel and open the "Profiles"
2. select IfcArbitraryClosedProfile and use the "dropper" to select your shape
3. click + to add a profile with the chosen shape

use the profile to define a wall type:

Use Add > IFC Element

1. Add
2. select IfcElementType
3. IfcWallType
4. Extruded Profile
5. Profile = New Profile (or the name you chose when creating it)

create a wall with the new type

click on Launch Type Manager icon

select the new type and close the panel

now you can create your new fancy wall (you can delete the original shape used for the profile)

happy modeling

Another option is to just add a half-space modifier and slice planes off of a square wall:

That half space puts a five degree taper on the wall.

Just wanted to say a big thank you to the OSarch community for your help with my questions on creating slanted and tapered walls in BlenderBIM. Your explanations and guidance—especially from @steverugi @sjb007 —were incredibly helpful. I appreciate everyone’s time and willingness to share knowledge!

You're very welcome @Abhishek
we are like a family here, we help each other

if you don't know it already, the 'profile' method to create a tapered wall is better when you need a type you can reuse over
for just a single wall the 'halfspace' method is much easier
happy modeling

Exactly @steverugi
Thank you so much! 😊 It really made me smile when you mentioned “family” — that’s exactly how it feels here. I’m grateful to be part of such a kind and helpful group. I still have quite a few doubts to clear up, so I’ll be posting them one by one soon. Happy modeling to you too! 🙌
