Walls from source poly errors

[Benson Shaw]

Horsing around with the Create Objects from Shapes >Walls.

Source poly (Side 1.) was made with polyline tool:

      Straight segment on y axis, then Tangent Arc vertices with tangent click on y axis.

      Side 2. is duplicate, moved over, then direction reversed.

 

The command seems to depend on direction of the source poly. Side 1 funky, Side 2 just right.

 

Known problem/bug?  One can delete the walls and reverse the poly(s) and run the command again. Or is there another strategy?

Either way, I think the initial direction should not matter.

So I do not see a reason why direction of the Path was reversed (?)

(I am used to hat mirroring things could cause any kind of problems)

 

And I do not get why the connecting Vertex between Line and Arc

moves ....

 

 

I think this is an unwanted behavior and worth filing a service request.

I reversed the path intentionally to demonstrate the problem and a possible workaround.  I had previously discovered through testing that reversing solved the problem , at least for this poly. Although, i think the poly with straight and tangent arc always produces the error in one direction but not the other.

 

Another workaround is to decompose the source poly. Downside is that resulting walls may need edit for consistent direction. 
 

In Side 1, I was very surprised to see the straight wall end vertex move, and therefore the wall angle change.  The short straight wall at end of the arc is about equal in length to the missing arc part (moved vertex) at start of the curved wall.

Annnd, add another tangent segment to the source:

Note - Wall creation option for Center was chosen here.  Right and Left yield same errors.

Arc wall is shortened at both ends, wall angle of starting and end straight segments is off axis (vertex moved).

 

 

Looks like Decompose, then Objects from Shapes is best practice.  Walls are as expected.

Direction of source poly yields same errors and walls of same direction???

 

 

 

Switched to light background for clarity of the wall directions.

Strange that the reversed poly yields same wall direction.

Just now bug submitted this.  Here are some revisions and extensions and the file.
