Arched Windows

[Jim S.]

I am currently working on a project that is a series of old masonry buildings with arched masonry openings but square windows, a fairly common condition.  In VW language the masonry opening is a "segment" top shape. The space between the square top of the window and the masonry "segment" lintel is filled by a panel.  The window sash does not follow the curve of the masonry opening.  

 

My question is how can you model this? If I chose a segment top shape for the window the sash becomes arched as well as the opening.  Do I really have to model the masonry opening as segmented, then the window in that opening with a square top shape, then an extrusion between the top sash and the curved lintel?

 

I have about 300 windows with many, many different sizes with this condition.  With the above approach I could make a series of symbols and groups but my head begins to spin thinking about how many I would need plus all the graphic overrides and more symbols to show the demo work on the Exterior Elevations. 

 

I am sure I am not the only one that has come across this condition with older buildings. What are some ways others have tackled this issue?

Do you mean like this Jim? (just to be sure....)

[Jim S.]

Yup just like that! There are both double and single windows as well.

Its a tricky one allright.  I shape the top of the window with a small elipse, but I know what you mean because actually the window is square. The only way I can think of which is immeasurably tricky would be to use an ellipsed cased opening for the masonry element in the main wall and then a thinner top shape square wall in the main wall opening opening to house a standard square window. But that's very fiddly!   The VW window and door tools need a good re-boot!  

 

It would be really good if the sash windows showed "horns" at the bottom of the upper sash (I think they are called) but that's getting a bit desperate!

Good luck

Aside from creating a Marionette to create & control this I think the only (viable?) option is to create a Symbol combining both windows, sill & header and Custom Wall Hole Component for each size.

HI Jim,

 

It is very tricky, but this is a horrible solution that I sometimes use on projects where fees are challenging.....It's quick'n'dirty but ok for 2D/low res images. Basically tweaking the spring and rise settings to keep the whacky geometry extending outside the object. try playing around with those 2 values and see what I mean....B
