An arc of a circle is the portion of the circle between two. Since there really isnt any random in solidworks, there must have been a curve that determines the path of the rope. The arc length is the length such a segment initially the length of an arc of a circle, but generalized to the length along some given path. How to create arc length and arc angle dimensions in solidworks duration. Using a curve driven pattern to obtain length of spline segments. But, in the drawing for this flattened view, i still cant insert an arc length. I have the actual length of an arc plus the length of the cord.

I just hope i didnt make any silly mistakes due to my overconfidence. If you have a sketch like that and you want to measure it, so start with the next step. Chord length dimensioning in drawing solidworks forums. In this post ill show you how to use the smart dimension tool to add solidworks arc dimensions, including arc length and arc angle. You can measure that curve by using the measure tool. Twice the radius times the sine of half the angle in radians. However, this can be automatically converted to other length units via the pulldown menu. Tricky way to measure a spline segment length on solidworks.
