create a triangular regular pyramid

dedperded2025 — Wed, 18 Oct 2023 07:17:07 GMT

I create a triangular regular pyramid from a reinforced concrete beam 500x500mm.
The problem is cutting corners.
Tell me how to do this?

If you want perfect corners, that's not going to happen with square beams. You need a small object, a family or model in place, that solves the corner and presents flat faces to the start and end of beams.

something like this....?

the key is having a common point for the 3 sides to terminate to.

Are those square beams or rectangular? What about the other three corners?

Yes. This is the best decision! Explain in detail how to do this in Revit with each angle?

i just did it as a Model In Place, that was the only way I could see to accomplish what you were looking for. currently it is set as Generic Model, but it can be set as any Revit Category in the list. i don't have Revit open currently, but I believe there are multiple Structural Category options available when doing a Model in Place.

if you have to use Beams... as @Alfredo_Medina mentioned, it's probably not going to happen.

This is very good! But I would like detailed instructions on how to do this. Please

People won't typically just walk you through an entire process. Try to do it yourself, and then have specific questions when things are tripping you up. That's the best way to learn.

If the category is not an issue, if you just want a pyramid that shows only all the edges not the faces, perhaps you could do this by using the pyramid mass family that is available in the Mass folder. Then use a couple of triangular voids to cut the faces, leaving only the edges with the desired thickness.

I don't understand what you advised. I need to draw a pyramid of reinforced concrete beams. A rotating logo of the developer's company will be installed inside the pyramid. The pyramid will be attached to the foundation with one vertex (visually an inverted pyramid with a slope of 30 degrees.)
Since we make construction drawings in Revit, I also wanted to design the pyramid in Revit from Reinforced Concrete Beams!!!!

Well, it is your design anyway. You must provide a solution for the corners in your design. How are you going to design the corners of a pyramid with bulky square beams 500 mm x 500 mm? How much is that pyramid going to weigh? What is it going to look like?

Wouldn't it be much lighter and better looking in steel round tubes? That would be easier to build, and it can be done with nicer connections at corners as well.

Using square beams for a 60 degree system is not going to look good and not going to connect seamlessly to be begin with.

I'm installing 2024 currently.... When it finishes ill upload the model I made with the pyramid, and you can reverse engineer it 😊.

Update... here you go. it is just a Model in Place. its currently in 2020 format so should be openable in any newer version. once you have it reverse engineered, you can make it as a family and add parameters to it to make it dynamic.

No. According to the project, the material of the pyramid is reinforced concrete monolithic beam. The company logo will rotate inside from a profile thick-walled 5mm metal pipe 50x50mm
