Problem with 3D Objects in section view

[Phileas]

Hey so I have a pretty specific window in my project that I had to create using 3D Objects because the window tool wasn't powerful enough to do it. Which means I can't add a sill to that window as easily as with the window tool. For aesthetic purposes, this window is set to have a double sill (one underneath the other, so that the condensation water from the window is evacuated, and an upper one that hides the lower so it seems like there is no transition between inside and outside (see my attached screenshots)).

 

In order to keep the building well insulated, the lower sill is set to be lying on insulation material and screwed to the window frame, and the upper one simply screwed to the window frame:

Here's a 3D view of it:

 

My Problem is the result I get in a Section view: VW renders a line that links the part of the sills, which makes the whole thing look wrong:

 

unfortunately I can't get these line to disappear... some help would be appreciated

Give the upper sill a thickness, a small one, that will take care of the line, the problem occur when you extrude a polygon with no thickness, Vectorworks tries to convert it to a closed 3D shape.

@Diego-Resuelvectorworks Worked perfectly, thx 🙂
