Constructing Curved & Inclined Wall & Associating Window

Anonymous — Tue, 23 May 2023 13:03:49 GMT

Hi,

I am learning ArchiCAD at the moment and working on a project.

I am trying to curve & incline a wall around a fairly tight curve that has a larger footprint on the ground compared to the curve that meets the roof.

I haven't managed to do this and have got stuck. My next step is to insert a window associated to this wall.

The closest I have got is an odd upside down half cone shape with a point on the top end of it.

(Also having trouble opening the interactive training guide at the moment)

Can anyone help me with this please

Matt

You could use the Conoid 12 library part.

Thanks for your reply Erika,

I have managed to view the interactive training guide now and the closest thing I can find is also what you have recommended. Actually the best shape I have found is Dome12 however I cannot change the vertical height of the dome so it doesn't quite fit properly?

I have cobbled together (fashioned in an unorthodox manner, if you don't understand my lingo ) a glass wall made up of strips of increasing angles of elevation to mold it round the shape.

I might just have to leave it at that? Any other advice would be appreciated

Thanks, Matt

Matthew,
You lost me on your last description. Can you post a sketch of what you are trying to achieve?

Also, I was wondering if an angled curved wall might work? Simple, easy, you can place a window in it or turn it's material to glass.

Hi Erika,

This image shows the glass wall I have made out of strips of glass to try and wrap it round the curve.

I have managed to inclined curved walls of a larger radius but on this smaller radius I haven't been able to.

The other thing is that the wall starts at 67 degrees on one side and as it comes around the other side it straightens up until it is vertical.

I am hoping to do this with a normal wall (not glass) and then place a window/ windows in it to fit.

Thanks for you help,

Matt

Matthew,
Interesting exercise. On the one hand it begs the question 'How would anyone build this?" A valid point.
On the other hand, we can build it in archicad, but we are still left wondering how you would really build such a pane of glass.

I created a mesh. Setting magic wand by number of nodes along the circle, I magic-wand a mesh on to the floor plan geometry.
Offset the base of the wall on the right slightly where the arc ends meet so the mesh won't be trying to create 2 nodes, one at the base height and one at the top-of-wall height, in the same vertical line.
Set the top of the wall to 10' (don't forget the end of arc nodes). Using the 'curve edge' pet palette method, remove the inside portion of the mesh but again, offset it from the top of the wall slightly (I used 1/8") to avoid the stacked vertical nodes of different heights.

Magic wand settings to get even sized facets of glass

magic wand contours onto mesh creating nodes along arcs. Set top of wall arcs and their end-points to 10'.

Adjust inside of wall top to match inner arc.

make a copy of this mesh.
Put it on the SEO layer.
Resize the mesh cmd/dtrl + k, making it just over the thickness of the wall smaller. My walls are 3" thick so I made it 3.1" smaller. This avoids stacked nodes at different heights.

Using SEO subtract the cutter (copy made smaller) mesh from the original.

You could tackle this problem with OBJECTiVE. Refer to the attached image. The conical 'wall' can be constructed as a single curved, twisted object (1) - it took about 10 seconds to set that up.

You can use SEOs to punch openings into the object, or you can use OBJECTiVE's Split tool to cut the object into sold and glazed segments (2).

You can see the results in 3D (3) and rendered (4). The features for twisting objects are still in testing, but contact me if you would like to give it a try.

Yes, it is so much easier with objective!

Erika,

Thanks very much for your help & taking the time to set those instructions out for me, I really appreciate it!

Will have a go at it soon!

Matt
