Hi there,
I am trying to create a thread in Solidworks 2011 using the helix and swept cut commands. I followed this tutorial (Solidworks modelling of M10 bolt a simple demo to start with - YouTube ) step by step, but mine does not seem to be working. There is no preview when I do the sweep cut, even though I have the triangle and helix selected. It works if I use the circle sketch, just not the triangle for some reason.
Is there a step I am missing? I copied exactly what the Youtube video did (he used a triangle too) and his showed the preview and worked. When I try pressing the green check mark, I get the message "Swept operation failed to complete"
Cheers!
Hello,
A few things:
1) Change your triangle width to .062499 (as stated above).
2) Delete your profile/helix coincident relation and create a Pierce relation instead (select the triangle vertex and anywhere on the helix, except its endpoint and select Pierce instead of coincident).
3) Create a plane offset off the end of the chamfer face (I went with a 1/32 offset).
4) Change the helix's sketch plane from the current face to the new plane. This will give the thread a running start into the cylinder.
5) The thread also dead heads at the other end which may not match fabrication realities (end.jpg).
Sorry, but I'm on SW2015 so the upload doesn't help you. But the above are the steps I took.
Cheers,
Kevin
