Sloped Roof with curved edges

[lopez_ignacio]

Hi everyone!

I am trying to create a sloped glazed roof with curved edges (Pic 1). There is no problem when the roof is horizontal.

If I enter some slope, all curved edges are converted into straight lines (Pic 2 as an example). As mentioned in another post, "number of full segments" is set to 0 and "defines slope" option unchecked.

Could someone tell me why is this happening? 

Would you model it in a different way?

Thanks in advanced!

If you do this roof by footprint, and then change the type of roof to glazing, the curved corner will be converted into a straight segment. But if you do the roof as a curtain system, the curved corner will remain curved. To do the roof as curtain system, first set a sloped workplane as the active workplane, then do a generic model in-place extrusion, then use the curtain system tool, select the top sloped face of the extrusion, and create the roof, and configure the mullions. Then you can hide or delete the extrusion.

Thank you @Alfredo_Medina for your comment.

I tried as you explain in your post, but when one of the grid lines ends in a curved corner, it changes to a straight line.

Left curved corner remains curved, the right one does not.

Are you Massing a Host? A Beam will follow that contour. Select 3D and use Pick Line Method to place the Beams along the Mass edge.

If you want to make the arc as smooth, you have to use the split element and break the arc to smaller segment

You will notice the arc with split segment will result in smoother curve than one straight arc.

If I understand your approach, I will have an outer ring of independent beams and a curtain system without border beams right?

In this case, if I modify the Mass, the curtain system will re-adapt to the new mass shape but not the outer beams (even if I lock them to the mass). Is there a way that the beams also re-adapt to the mass?

I see in your example, and tried myself, that this solution just creates shorter straight beams instead of shorter arcs, isn´t it?

It is a pity that the designed tools (Sloped roof and curtain systems) allow curved beams in flat elements but not in sloped elements.
