Mullion location within curtain grid

[Rick Moore]

What controls this? I can't find a way to change this or even tell what the default is

[Alfredo Medina]

Select the mullion > Edit type > Width on side 2 or Width on side 1 are the parameters that control that distance. The default value is half the width of the mullion type.

[Rick Moore]

Thanks, Alfredo. Those type properties are off center and greyed out, how would this get locked down?

[Alfredo Medina]

Well, it might be that the profile being used for the mullion type that does not have these reference planes and parameters, therefore these settings become unavailable.

[Rick Moore]

Yeah, they're not in the profile. But I got what I wanted by making the appropriate reference plane 'define origin'.
