Ramp with different angles of inclination

[adri2906]

Hello everyone, I'm new to this Archicad forum, and slowly I'm getting the idea of using different objects to perform any or almost any architectonic shape or object I need for my projects. In this case I need a Parking Ramp with 3 inclinations: less than 4% in the first and last 4 meters and the rest can be MAXIMUM 20% (that in a 3.1m slab parking I'm calculating is way enough and gets automatically calculated but surely under the 20% limit the rule imposes. I'm actually trying to do it with Ramps from the Stair Maker and Create Stair advanced options. With that set I can only choose a linear ramp with 1 inclination or a ramp that has a fixed inclination on the center and a way sloped inclination on the start and end (I've tried to impose the 4% as an angle that is around 2 degrees on this sides but this ramp is made for pedestrians so it doesn't bend LESS at the extremes and MORE in the center). Should I choose the Roof tool, I would like to avoid the mesh if possible due that the ramp is just a diagonal concrete slab that has 3 angles. Can you help me? Thanks a lot.

Rooftool is very easy for making ramps with a fixed thickness, mess tool is good for making sloping terrain features.

There are some ramp objects and you can also make ramps with stairmaker.

You have 2 options here:
1. Use the Roof tool were you can specify the angles
2. under Objects you should have a Parking Ramp object that you can configure the transitions.

I would never use the stair tool to create a ramp for this.

I did this yesterday with three roof elements, cut them in section and stretched the slopes as required following some temporary construction lines.

adri2906:

If you use the Roof Tool (this would be my choice), use Single-plane Roofs, they can be intersected automatically, in the help files see: Elements of the Virtual Building > Construction Elements > Roofs > Editing Roofs > Intersect Single-plane Roofs.
