State roof and wall profiles so secondary members can be drawn together. A profile change often changes purlin spacing.

Align the frame and secondary members before sheeting. Gutters and window flashings need details, not scrap.
Tick whether secondary members are included before comparing price. No single spacing or thickness is set here.
