Draft for parting line

Miguel_GT

Hi,

I am trying to do a draft for parting line and OnShape does something extrange.

Why does the small cylinder right and the big one wrong?

I tried different Pull direction and the result is the same.

Thanks for any help

Was the big cylinder already split into 2 faces before you added the draft ?

Miguel_GT

No. Both were iqual made.

I don't understand the vertical edge in the big one.

Thanks

You might try extruding the large cylinder (Extrude 3) before the connecting bit....that way the faces may not get split.

Are you sure that Sketch 3 is fully tangent to the sides of the connecting bit?

Miguel_GT

You were right.

Something was wrong in Scketch 3. I did it again and no vertical edge.

And draft was ok.

There is another draft in a rib and I had to do it twice.

And the other side.

I do it in Inventor only once.

Is it possible with OnShape?

And is there concentric Hole? Using projecting edges or other geometry.

I could finished the model.

Thanks for you help

For the draft on the rib, you can simply select both sides of the rib and you can do both sides of the rib in one feature:


For the concentric hole, you can use the Hole feature, and select a sketch point, or the new Mate Connector feature for hole location:


There is also an Offset tool in the sketcher that you could use to offset the edges of the hole from the outside of the post features:


Good luck!

Ok with draft on the rib.

The last option for the hole was clear for me. In fact, I did it on the first sketch and then extrude-remove.

The first option is the one I was looking for. A geometric reference on the solid with Mate conector.

I like OnShape more and more.

Thank you so much for all your help.
