In BikeCAD version 19.0 in the Stays (auxiliary view) >> Chain stays >> General tabs of the Dimensions dialog box we have a new dimension for the Cobra Framebuilding Stay Slayer spacer width. This width across the chain stays is meant to be measured 90mm from the center of the bottom bracket. However, if you are using a variation on this design, you'll find a tab for this in the Fixturing dialog box. You can change the Stay Slayer offset value from 90mm to whatever you require.
