Surface holes

[47stinson]

I received an IGES file from a customer which appears to be a solid body made up of surfaces, with a series of holes in several sides. There is no other information about the holes. I can dimension the part by snapping to the endpoints of the surfaces, but I can't get the cursor to snap to the hole edges or centers. Is there any way I can get the hole sizes and locations? Using Ver 9.1.

Maybe you have splines, which is why MC won't snap to the center of them. Try Modify-Convert to arcs.

 

If you don't have any wireframe, then you can create it with Create-Curve-All edges. If for some reason the holes come in as splines, use the method above.

Try modify>convert>plines>to arcs.

create/curve/one edge should give you something you can measure. You could also try analyse/surface/curvature or analyse/dynamic

Thanks, guys. Those are good ideas to try in the morning.

m2c,

if your holes are on curved surfaces, they will always be splines (unless there is flat edge somewhere like a c-bore), in which case you'll have to xform>squash them to a flat plane, then convert to arcs, then measure.

 

edit: another option is to get on the horn and ask the "artist" what size holez he wants, not to mention a tolerance.

Create an Edge Curve on the edge of the surface and then from the top view do a 3 point arc.

Or see if you can get the Solid Model from your customer and use Solid Drill to automatically drill the holes.
