Creating a surface?

[mhesse]

I need to take the axis of a cylinder and pierce it through a curved surface for a true position. The problem that I have is, I only have Cad not Cad++, is there more than one way to create a surface? I have tried points and i get a message that i need a scan with more than 1 line in it. I can't get a scan with more than one line in "Cad" Version.
right now i had to create a plane around the cylinder and pierce my cylinder throught the plane, but I know this is creating a small amount of error and I do not have alot of tolerance to begin with.

[Tested]

If I remember it can only be done with a PATCH SCAN.

That's what I thought. I need more software (cad++). I was hoping there was a way around it.

thanks

Do you know what the nominal is for the pierce point?
Do this:
1) create a offset pt at your nominal
2) go to construct , plane - click perpendicular, highlight your cylinder, than highlight your nominal - and click create.
This will create a plane perp to your cyl at your nominal.
3) Next, intersect your cyl and your new perp-plane.
There is your pt.

Is your suface a plane?. If it is you can just measure a plane around the cylinder and create a pierce point with the cylinder and plane.

Also, the SURFACE CREATION in Pcdmis if very clunky and can take a horrible amount of time. I can take the same data, export it, import it into a cad system, create the surfaces, export them, import them back into Pcdmis in much less time and with better results than I can using Pcdmis.

it is a curved surface. the position is called out as normal to the curved surface.
I think kev's idea will work. Im not sure it is "exactly" correct but is better than anything I have come-up with or have the ability to do without scanning.
Thank's Kev. I was not sure the best way to do this
