To have the ability to create brick arches and jack arches per the BIA standards. You could go to The Brick Industry Association web site to get all the specifications for them
This would help the productive of a CAD Tech when they have to create one of them. Have a dialogue box that you can specify what type of arch and jack arch. Such as give the width of the window / door and indicate 3c or 4c and etc… This could have the option to be created in 2D or 3D format.
Thank you,
