Random holes drilled in work
PostPosted:Mon Aug 02, 2010 7:35 am
I drew some rectangular perspex covers with a few holes drilled around the outside (the outside holes are drilled then self tappers are used to hold the work piece down to a sheet of MDF to allow the part to be profile cut from the stock).
The software has generated an extra hole at centre of each rectangle - these are obviously not round holes but it has made a hole at the centre of the part.
I need to be able to only select the round holes - I seem to be only able to select the round holes if they are on a flat surface. If they are not on the surface but only on the waste material outside the work piece, how can I select only them and ensure that the centre of the part is not drilled?
I am confused as I made a few similar parts last week and they were all fine - it seems to have suddenly decided the drill any centre it can find
