Boolean Operations

[P Gannon]

We are a High School running VW/RW (60 licenced seats, latest update) on a Windows 2000 Professional Network. Machines are Pentium III, with 128 MB RAM. When attempting to perform Solid Subtractions which involve a Sweep/s, we frequently get the error message....'The solid you have tried to create cannot be computed. Edit the geometry........ and try again'. What does the message mean? How does one 'Edit The Geometry'? Why is it that the same operation does NOT always have the same response, (ie if you tried that operation at a different time it may work perfectly?) Changing the 3D resolution in the preferences does not have an effect. Regards P Gannon

My only experience with that particular error message is when the two masses you are trying to subtract are not actually intersecting. In other words, they share no mass. While it may appear that the two objects intersect from one angle, your best bet is to check all views to ensure intersection (i.e., top; left; right, etc.). Of course, same applies to Solid Addition and/or Intersection as well.

Thanks for the reply Jack. However the objects on which the operation/s are being performed ARE in 'contact'. This therefore cannot be the reason for the error message.
