Rafters with Decorative ends

Anonymous — Tue, 23 May 2023 13:10:28 GMT

Anyone have a good process in drawing a "gazebo" roof framing for lack of better words? The plan shows a pyramid roof at 10:12 on all sides, 9' square. The model will show the open rafter ceiling, with decorative ends to the rafters.

It seemed simple in theory but it's becoming more difficult to do, or figure out rather.

I thought to make a custom profile and extrude the thickness of the rafter, but I cannot modify that profile to stretch it for the corners that are deeper and take....I will just post a photo of what I am doing.

What's missing in the photo is the decorative rafters.

Thanks!

and on you Mr. Larrew for taking a vacation!

This is easy with OBJECTiVE. Following the attached image:

1. Draw the shape of your rafter using a fill or slab and use OBJECTiVE's profiling tool to make an elevation profile object from it.
2. Use 'OBJECTIVE/Tools/Rotate' to incline it to the pitch of your roof and multiply it at whatever rafter crs you require.
3. Use 'OBJECTiVE/Tools/Split' to cut the rafters to the hip
4. The finished result in 3D.

Have you tried making them all the same and then just using the adjacent roofs to SEO the ends of the rafters?

I just tried it and it worked great. However, you have to SEO twice, once with upwards extrusion and once with downwards extrusion to get the rafters to clean up properly.

BTW.. you're CUSTOM PROFILE idea would have worked...

1. Create profile as if level (no slope)
2. Use HORIZONTAL STRETCH
3. Make profile available to BEAMS

4. Apply profile to beam
5. Use BEAM's ROTATE parameter to match roof slope
6. Use modified slope to match HIP slope

Someday will have profiled edges for SLABS and ROOFs and this discuss will be moot.
