Intersecting planes and measuring along surfaces

Intersecting planes and measuring along surfaces

Intersecting planes and measuring along surfaces

(OP)
I have a catpart with curved surfaces - on these surfaces are a number of holes - I have created a plane that runs approx. through the centre of the holes and I have then intersected the catpart body with the plane which then creates an intersect line but how do I measure from hole centre to hole centre along this curve (i.e. not shortest distance) - I know you can measure along a surface but I am having trouble pointing points on the intersection line at the hole centres and trimming the line back to these for some reason - Any advise anybody ??

RE: Intersecting planes and measuring along surfaces

Are you working with surfaces or solids?

RE: Intersecting planes and measuring along surfaces

(OP)
I have a model with a CAT.Part extension if thats what you mean and I was in the GSD workbench.  Yes the model I have for ease of explanation is similar to what you had posted

I was intersecting the part with a plane after I had extracted the surfaces and was then splitting the intersection line with points (that were on the hole centres), but then found out that I could create a line along the surface by using create line pt-pt and using the surface as the support, but as I have extracted several surfaces there are changes in section and even though I have joined the extracted surfaces together (surfaces now in a Geometrical Set I created) I still have issues when I create a line using two points due to different areas of this joined surface are created from different surfaces and the line looks continuous but when you click on it it actually only shows that part of the line until it meets the next change in section - if you can undertand that bizarre what am i doing wrong ??

I have another annoying query, if some holes are on a change in section so when you click them the were effectively two half a holes (I know you can't get half a hole but just to explain), so when in GSD and you create point using circle / sphere centre it fails when you select the hole edge as it sees it as two holes - Any advise ??

Thanks
