<p>Hello Djordje</p>
<p>yes they are some problems. Mainly they are due to Boundary Volume components, but indeed it is due to Rhino method "<span class="identifier">Brep</span>[] <span class="identifier">CreateSolid</span>( <span class="identifier">IEnumerable</span><<span class="identifier">Brep</span>> <span class="parameter">breps</span>, <span class="identifier">double</span> <span class="parameter">tolerance</span> )".

<p>Hello Djordje</p>
<p>yes they are some problems. Mainly they are due to Boundary Volume components, but indeed it is due to Rhino method "<span class="identifier">Brep</span>[] <span class="identifier">CreateSolid</span>( <span class="identifier">IEnumerable</span><<span class="identifier">Brep</span>> <span class="parameter">breps</span>, <span class="identifier">double</span> <span class="parameter">tolerance</span> )". I tested it and it ouputs many volumes but not the one we need. I suppose David took the volume with the biggest volume. </p>
<p>So as it is not cool to let an unresolved problem I wrote a C# component. It seems more robust. Sometimes you will have to play with tolerances and recompute solution. I parallelized the component so it is fastest with many curves. </p>
<p>Angle of roofs are 45° but it is easy to change with a NuScale. </p>

To calculate a sort of medial axis of a volume. But it is curve not volume. But as you write at all discussions of medial axis I suppose you want medial axis for 3D shape. But I think medial axis for 3D must be surfaces because on 2D you can make the shape with medial axis ans disc. In 3D you can make the shapes with placing spheres on surfaces.<br />
You can search also on skeleton for mesh<br />
