Hello all,
Ive recently noticed that if sweep profile sketch (surface or solid) contains sketch fillets and offset; and also using keep normal constant option, resulting sweep has one all around face instead of selectable separate faces according to sketch entities. see image.
is there help? ive seen old SR-s about it but in 2014 version i have same issue. I have few workarounds but is there a straightforward solution?
Thank you for help,
Mile
My guess would be your sketch on the top is made up of one line. like a fit spline maybe.
No, its all circular radius and lines...
Can you post your part for us to look at? What version SW are you using?
I think the reason is that when you keep normal constant the profile shape normal to the path is changing, so a cross section would show that the arcs are no longer circular, but become oval. Since they aren't arcs anymore I think that's why SW doesn't separate the faces.
But if you absolutely need the face divisions you can sweep each segment as a surface sweep (still keep normal constant) and then knit all the surface together.
See attached part. Im using 2014 Sp4
i have workarounds, but now i realized basic thing - normal constant keeps section parallel so on a curved path radius change shape from circular to oval so only "unchanged" surfaces are available for selection.
also workarounds are do it separate with surfaces, or do it follow path and trim ends...or in this case do it with sharp edges and add fillets later...
