Hi,
I have this question on surfacing...have been using Mastercam for quite sometime but never figured out...

What I've been trying to do is to create a curved surface along two chains(file attached for review). Right now the surface is STRAIGHT between the chains, but I want it to be concave all along the chains.
How do I achieve this, can someone help?


Thanks in advance,

Ken

Are you looking for something like this picture. I used Swept surface after creating a arc endpoint at one end.

Great!
Would you tell me how to create the arc in detail? That's what I was having trouble in drawing. I couldn't get the arc end point to touch the both chains.
Maybe I need to create a new plane to draw on?

Thanks a lot!

I created a new plane using Dynamic plans. used the end one for the gnomon then tagged the X axis to the end of the other and then rotated the Z long on the rails.
