Creo 2, M160 (I also tried Creo 3, M070 with the same results)I have a sketch consisting of a single arc and I want to control the length of the arc, not the radius. I've constrained the ends and I've tried adding a perimeter dim or adding a chord dim by selecting the arc, one end, the other and then middle button. Creo won't let me add the dim, it thinks the dims are too small. I get an error "Please increase the number of digits" or something about sketcher accuracy. I can get it to add the perimeter dim, and I tell it to vary a linear dim that is 0.002", however it flattens out the arc to it's maximum length and turns my 0.002" dim to 1148.477". The sketch is then locked up and unchangeable.There used to be a setting for sketcher accuracy, but I cannot find it. Does that still exist? If not, how do I get Creo to accept this perimeter dim?I cannot share the model due to client confidentiality.
