Spans with mitred corners

Hi,

I am trying to create a scaleable window assembly. The frames of the windows are moulded and mitred at the corners. I am struggling to wrap my brain around how to split this down into different comments, profiles and spans so that I can adjust the overall width of the window whilst maintaining both the proportion of the moulding and mitre junctions.

I know I could split the frame after the corner of the window frame and have the all the horizontal frame pieces extending horizontally in a span (as the glass does), but I don't want to do this because it will introduce a join line where there shouldn't be one.

I am sure this has been answered before so can someone please point me in the right direction of where I can learn how to do this?

Thanks very much.

You could consider making the mittered intersections a component that repeats only at the corners. The horizontal members can be spans in between them. The corner components can have hidden edges where they meet the spans. The edges of the span would still be visible however.

Thanks Omar. As you say though, this will introduce a visible edge that shouldn't be there. If I create the whole frame as a component and scale to fit it as a span, this will maintain the mitres, but it will still throw out the proportions of the moulding when I scale the windows.

With version 4, you can hide the ends of the profile spans to be visually continuous to avoid this problem. I agree with Omar's suggestion but you will need to use PB4 to solve the visible edge problem.
