Soft Edges with Follow Me

Developers Ruby API
1

When I extrude a profile with the followme method using the API I’m getting soft edges. I’ve never noticed this before but I’m wondering if anyone else has encountered a similar result. My code is fairly simple:

group0b = Sketchup.active_model.active_entities.add_group
entities0b = group0b.entities
edges0b = entities0b.add_curve @pts_aligned
			
group2 = Sketchup.active_model.active_entities.add_group
entities2 = group2.entities
new_face2 = entities2.add_face ftg_profile

status_ftg = new_face2.followme(edges0b)

The only thing I’m doing different here from previous code is generating the path with the add_curve method, but I don’t see why that would create this behavior.

The @pts_aligned array is an ordered set of points. The ftg_profile is also an ordered set of points in an array. It all works great other than I’m getting soft edges.

The workaround seems to be this little function/method:

def unsoften_group(grp)
    grp.entities.each { |e|
      if (e.kind_of? Sketchup::Edge)
		e.soft = false
		e.smooth = false
      end
    }
end

However I would rather not to have to do more work (computationally) if it can be avoided.

The stemwall footing had the unsoften_group method applied to it whereas the stemwall itself has not in the image below:

curves always produce smoothed ‘extruded’ edges, so you either use edges, explode the curve or unsoften as you create them…

That was my suspicion all along with the curve entity since this was the only thing different between other chunks of code that did not create a smoothed solid. Thank-you for the solution and explanation.

The addition of this one line of code eliminated the workaround and softening method:

edges0b[0].explode_curve
