I thought we covered this a couple of weeks ago?
Where are you getting these imaginary dimensions?
In the real world we cannot manufacture beyond 2 or 3 decimal places - so if you see an 8-decimal place driving dimension you are making up imaginary dimensions.
Yep, I found it Dimension in spring
All you had to do was edit my dimensions.
Your problem is in sketch 3. Delete the 5.15 radius and the dim to the end point. Make the rad tangent to the line and the ends coincident.
