First-time poster, welcome. Use [ CODE ] and [ /CODE ] to make the program look like it does on the Pcdmis screen.

I would suggest you measure a line on the bevel, BUT you need to be in the correct workplane for it to come out right. Rotate the view using the 3-D rotate until you can see where the line should be, then use the cube face you see on the rotate for your workplane. If you are not in the correct workplane, it will not make the line right. ALSO, you could try doign individual points and constructing either a 2-D line (using the correct workplane) or a 3-D line, then use that for dimension. HOWEVER, the dimension will also have to be done in the correct workplane. Pcdmis has to be able to 'see' this angle and it needs to knwo from which direction to 'look'.

I,m trying to write my first program, and not having a easy time of it. I was in Chicago last week for a PC-DMIS cad course. I thought I had a grasp of the principles last week but now I'm wondering about that. My problem is that I have a cylinder bored through with two beveled edges at one end. I need to measure the angle of the beveled surfaces to the end face of the cylinder,and the distance from center line of the part to the edge of the bevels. I did not import CAD file I have done everything manually. The face of my part is my work plane that I leveled to, I set rotation off the center bore and another hole in the face of the part. I set my X & Y origins at the center bore, and Z origin at the face. I have sucessfully measured all other features on the part at both ends of the part. My problem is that when I create a plane (or line I tried both) on the bevels so that I can constuct a line at the intersection of my bevel plane and work plane to measure my distance from center line of the part to the edge of my beveled surface every thing seems fine. When I run the program however it takes one hit and errors out. It tells me unexpected hit. It seems to be taking the hit in the correct location however. I just seems that it is maybe traveling into the face of the bevel to far. Sorry for the long post I wanted to be discriptive. I've included a portion of the program, and attached a pdf of the part.

Thank you,
Ken Baker

Your hit vectors are opposite signs of your actual vectors. You ought to try rotating to the nominal angle of the plane and so you can take hits at whole number vectors instead of guessing if your cosines are correct.

**Underspec** · 09-19-2007, 07:26 PM

Switch to a workplane that is perpendicular to the planes you are creating, ie. X or Y depending how you are your part set. You have to change workplanes before creating the features.
