Re: Another equation curve approximation error
Evalgraph() also causes some very choppy curvatures...The curve equation is as follows based on a cosine-approximation spline in the graph: r=ID/2theta=t*360*TURNSz=evalgraph("graph_1",t)*LENGTH The...

It looks like PTC could do a better job on matching at least the first derivative. It isn't clear whether follow-on geometry is adversely affected to a noticable extent. It's possible that the...

I will let you interpret this result. This is the grapheval() curve with 3 consecutive sweeps:
View ArticleRe: Another equation curve approximation error
It's consistent. What do you mean consecutive sweeps? I think an excellent blog for PTC to start is "How this function/feature actually works" to explain the nitty-gritty of this sort of thing.

Re: Another equation curve approximation error
I used the curve to define a swept line (outward) 1/8" long; used that edge to sweep a new line (45 degrees, 1/8" long)... and used that edge for a 3rd sweep. The graph shows all 3 edges. When I do...

This is a comparison of the initiating curve (cylindrical half wave cosine) and the results from the edge of a swept surface along that curve. Accuracy is default. This is the analysis of the 3rd...

Next was the evaluation of the EvalGraph version. Definitely cumulative!The black is the curve reference; the second is the edge of the 1st sweep, and the 3rd is the last sweep I swept a line out,...

Re: How to show text instead of dimensions without overwriting?
You can also use "show dimension symbol" by adding &S and changing your Dimension name,(X in my eg) and adding the required text is suffix or prefix column..
