Join a Surface and fills
(OP)
afternoon, Ive searched and searched but can't seem to find anything. I have a surface whihc has been extracted from a block, however the block had holes in it, so I've filled said holes. I now want to join all surfaces, but create one smooth surface, as I need to cut another block with the new smooth joined surface, and for it not to leave round curves where the old holes were.
thanks in advance, picture attached

I would create an offset (say 5mm). it takes away the shapes and edeges and then I would Rough offset it back to where it was originally.
hope that helps,

extract the outer boundary and then use the Fill command. it will be identical to the original wihtout the edges shown. I tried it on a none-planar object and it worked.

You used a ruled surface.
I will have some reserve on your method if the surface is not ruled.

I just tried it with an Unruled surface and it worked as well. please see attached catpart

The problems you describe are not unusual. As I said, CNC software tools can be quite sensitive to surface quality. And the problem is made worse when you convert the CAD model to an .igs or .stp format, and then import that model format into the NC software format. Converting the digital data file from one format to another is not an exact process, and usually produces small errors in the data during each translation. It's these small errors in the digital data definition of the part surface boundaries that cause problems in how the NC software calculates the tool paths. For example, if the file conversions produce enough of a numerical rounding error at the digital definition of the boundary between the hole fill surface edge and the parent surface edge, when the NC software sees the gap/overlap at this interface it will not know what to do, and will record an error. Some companies I have worked at require all CAD models to pass a surface quality check process before they are released to manufacturing. I have also seen similar problems with CAD models submitted to stress analysts. PATRAN seems to be especially sensitive to any flaws in the quality of the CAD model surface.
