Cut surfaces in 3D - Building Materials

[Anonymous]

Can someone tell me why this wall shows the surface for the building materials at the top of wall, but not at the end? Am I missing a setting somewhere?

I have noticed that with a composite wall I am not able to activate the
over-ride button, when I click it nothing happens. I have a
Watched the video and i cant see what Im doing wrong.

The override surface settings work a little different between a Composite and Profile. For a Composite Wall you have 3 surface overrides (outside/inside/all edges), for a Profile you have only 2 (extrusion override, ends). You need to depress the end/edge button in the Model panel under "Override Surfaces:" then the skins will appear.[/quot

The override buttons only appear when "Legacy intersection methods" switch if off - under Project Preferences > Construction Elements. The legacy mode is needed for migrating files.

You can tell if it's on, if the Model panel says "Surfaces:" (legacy switch on) or "Override Surfaces:" (legacy switch off).

Erich,
Can you show an image of this situation?

Here is what I am seeing. This is a wall that is trimmed to the roof above (roof layer is turned to wireframe for this view). The wall has an override for the exterior skin but turning that off does not have an effect.

Erich,

If you use connect options from the context menu (trim or merge) then the skins will intersect - between the Composite Wall and Roof, and the surface show correctly. Are you using this Trim or the old Crop function or SEO?

Erich,
Is it possible that you have the Custom radio button selected in the Filter and Cut Elements in 3D Dialog and a white surface is selected for Custom surface?

Thanks James that was it.
Although I still see nothing in the model panel, that says legacy is on or off

James,

I am using the "Crop to Single-Plane Roof" command. The Trim Elements to Roof/Shell command from the context menu does not work with Single Plane roofs (at least for me).

Laszlo, yes the custom button was selected, but has nothing to do with this cut (I tried with it on and with it off - and the surface was set to black not white)

This smells like an unfinished feature with the antique commands I tend to use.

But I have no surface override buttons? I am locked in to various.

Plus all my Building Materials have a warning symbol. But I have no information as to what the alert is.

It isn't very clear but that warning symbol means your legacy mode is on and that is why you don't have any material over-rides.
