    Split Surface and Offset?

    Brent Theobald

      Hello,

       

      I want to divide a face. Then I want to offset that face to make a pocket. I understand what I want to do in other CAD packages. I'm struggling to get it done in SW.

       

      So far I am offsetting a face. Then extrude another feature to intersect it. I knit these all together to form a solid. Then I can subtract the two volumes.

       

      Can anyone suggest a simpler alternative?

       

      Thank you,

       

      Brent

              Hi Brent,

               

              • I want to divide a face.

               

              MAB - Insert>Curve>Split line    You can use a sketch, surface or plane to divide face/s.

              MAB - insert>Surface>offset   you can offset the divide model face or surface

               

              • Then extrude another feature to intersect it.

               

              MAB - create sketch, then surface extrude

               

              • I knit these all together to form a solid.

               

              MAB - insert>Surface>knit

               

              • Then I can subtract the two volumes.

               

              MAB - insert>Features>Combine

               

              Can anyone suggest a simpler alternative?

               

              I think you pretty much have the right method. Of course there are other clever ways. Here is mine:

               

              Create your splitline, then create a 3Dsketch, convert entities on the split line (so that 3D sketch geometry is inserted into the 3D sketch), create a vector for cut or addition of material, then use the 3Dsketch to cut or extrude offset from existing splitline face (extruding with 3Dsketch automatically caps the non-planar ends)

               

              Regards

                  You can use the "surface extrude" funtion to make a pocket in a solid body. Yes, that is very counter-intuitive, but this ability was added in SW2011.

                  You have to first make the split line. Then you select that face before you initiate the surface extrude function. Select the sketch plane as your vector (it will be normal to the plane). Then turn on the "cap end" "delete original faces" and the "knit result" option, and it will always be a solid body, never a surface body.

                   

                  Just two features, the split line, and the surface-extrude.

                    Hi Mark,

                     

                    That was exactly what I was searching for. I knew there had to be a less cumbersome way of getting where I wanted to go.

                     

                    I appreciate the other responses too.

                     

                    Thank you,
