Why Why Why ??????

[Robert Masters]

Can anyone out there tell me why, when I click on the part model surface where I want to create a point, the animated probe travels THROUGH the model and my point ends up anywhere except where I want it ??????

Solid or wireframe? If solid click on surface icon prior to taking points.
Are you using autofeatures? more details please.

It's attempting to be intuitive. Rotate the model such that it is at an angle instead of directly parallel or perpendicular to the programmer. This happens to me most frequently when using conical features.

For future reference, could you please include some information in your user profile...i.e. type of machine, controller, version, etc. etc.

Thanks and welcome to h e double toothpicks.

James has this one nailed right on.

I often encounter the same thing. Rotate the model, then click again!

Occasionally there MAY be holes in the surface you're picking and guess where you're going to take a hit? Right on top of the area that didn't surface worth beans. Also sometimes the vector of the surface you're picking may be wrong and PCDmis will pick the wrong side of material. This is what happens to me most often. If I have design swap the vecor on the surface I want it USUALLY, clears this up.

Speaking of that. PC-DMIS 4.0+ has the ability to fix vector problems for all vectors of surfaces in the CAD model. I have used it and it works like a charm. Another "+" to using the newer version.

I'm using version 3.7 on solid surfaces. These are not autofeatures. I haven't had any trouble measuring surface points on the part....yet.

I've got a Brown & Sharpe 9-12-9 machine (circa 1992) with a B3C controller upgrade (I just got a nice SP25M scanning probe too

Yea, If you are in "Curve Mode" and you have a model with lines, curves, points, etc, PCD will attach the point to the nearest one of those features.

If you want to probe a surface you will need to switch to "Surface Mode".
