    Lock nuts vs. pinch bolts on suspension links

    Most race cars use turnbuckle type adjusters to lengthen/shorten the pushrods to adjust ride height. Most seem to do it using jam nuts to lock the turnbuckle following an adjustment. E.G. http://www.chironworld.com/parts/images/uploads/100_0158.JPG However I noticed recently that the Porsche...

    Non-connex errors

    I'm creating a solid in V5r9 from an existing Iges wireframe/surface model. Due to the complexity of the original surface (not all of which I need in the solid) I am creating new sufaces using sections of the existing wireframe. When I try to join some line/curve elements I get 'non-connex'...
