- cross select for sweep2rail. So to not select the two rails separately but with a cross selection.
- osnap isolate. I have always have some osnaps selected, but sometimes I like to use one. I know this can be done for one time, but if have to copie several times only in the centre. It could be handy if the one time (alt) can be done with a on and off function to isolate an osnap.
- one major improvement could be is a stroking function for surfaces. srfblend does this kind of but this is not always possible and not working all the time. Also when editing a blended surface (corner between two surfaces) the blend is not stroking automatically.
While working I come up for more things I think version 5 is missing.
