Please tell me how to make a ramp like this.

I can't make the connection part accurately. ^^

The problem is that it is difficult to process the green line part.

A beam with complex profile at correct inclination might work

Is it possible for me not to do this?

I would use a mesh.

LeeJaeYoung — Sun, 03 Dec 2023 04:34:02 GMT

Is the answer to make it a mesh or a morph?

However, there are concerns about whether the thickness of the slab can be accurately determined.

Try making it with roofs and use Intersect Single-plane Roofs.

If that doesn't solve it then you will need to place a flat transition where the roofs meet to turn the corner. That is the only way to eliminate the twist where the beams are meeting in your picture.

Thank you for answer.
It seems a little off. ^^

Yes, either.

Another option is to use 2 Slabs.

Convert to Morph

select the vertical planes

move them up (or down) in 3D Window

But I think that per IBC Code that corner needs to be flat and ADA compatible so all these suggestions are moot.

You should also note that in @Eduardo Rolon image, there is a new line in the ramp (red). This tells you that the 4 points forming the slab are no longer on a single plane and the top face needs to be formed by two triangles. This could be a problem for your finishes.

It is registered as an official ramp in REVIT, but I think it is not officially registered in archicad.
Various ramps are made in this form (without ramp landing), and I hope it becomes an official ramp.

The revit tool works with straight paths and landings, I'm not sure where you got that image. It could achieved with the roof tool BUT you must understand the geometry and what happens where it meets the floors. To use the roof tool the top and bottom ends of the roof / ramp need to be parallel to the roof pivot line or they won't meet the floor levels properly.

Also if the roof pivot line isn't at 90 degrees to the walking route then the surface will fall to the side of the ramp. This can be good for drainage, but too much can be a problem for walking or wheelchairs etc.

The best way to learn is to play with the roof tool. Look at the floor connections and take sections. You might then understand the problem and why your original design may be difficult to build.

If you can't model it, then the builder might struggle to build it.

It shouldn't be all that hard.

Flat slab for the corner landing and inclined beams or roofs for the ramps.

You could probably even play around with the stair tool and create the ramp.

@Barry Kelly You are 100% right with your solution but I get the impression @LeeJaeYoung doesn't want to form that flat transition.

Re: Please tell me how to make a ramp like this.

Barry Kelly — Mon, 04 Dec 2023 09:34:26 GMT

As you alluded to in your post, if the landing is not flat, there will have to be a lean across the width of the ramp which might not make it too comfortable to use.

FWIW even if it is listed as a ramp in Revit doesn't mean that it is code complaint.

Cars can use it, people will find it difficult.

You can make a door that is 12" (0.3048 m) in height and width in both softwares, doesn't mean that people will fit.

Hi! late to the party, but this is how i would do it too. The stair tool actually solves it quite nicely, but i havent found how to eliminate the steps and leave only the slabs, which would convert it effectively into a stair/ramp tool
