Slab with 1.5% slope

Hi, can I draw a slab with a 1.5% slope ? I also try to use the roof module, but with little slope there is an error. The object turning or mirroring arbitrary.
Best regards, Simon
PS. we use VisualARQ on Rhino 6

Hi @simon12,

When you work with small angles make sure to reduce the value of the Angle tolerance, for example to 0.5 or 0.1 degrees.

In the case of roofs the value for the inclination should be provided in degrees. We will add the option to introduce the value as percentage in a future version.

To create a slab with inclination first you should create the contour planar closed curve that will define border of the slab and then use the Slab From Curves tool.

Kind regards

Perfect ! Thank you very much.
Have a nice day, Simon

I have tested and it works perfectly.
