angled arc

[CFDruss]

Hey all, how is the best way to create a angled arc. I.E, say the arc is created on the xy plane, but you wanted it to tilt in to the z axis aswell???

Sorry for the noob question

So this is sort of like a cylinder with draft applied? If you can, create a cylinder & add draft instead of trying to use the 2 circles.

If you don't have enough known info for the cylinder, then instead of putting points on the quadrants, TRIM the circles so that they are both 180 degrees, then mirror the resulting arcs to get 2 arcs making a complete circle. Make sure you perform the trim at the same location for both circles. Once you have that, the Freeform Feature called Through Curves will give you what you want unless you have a guide path that is not straight. Refer to following image:

I made the 2 arcs different colors to display the trims for you. Just select the curves in similar locations & everything should align OK for you.

If your guide path is not straight, you want to use the Freeform Feature called Swept. When you use Swept, you will have to have a guide or path curve that defines the path the circles are swept along. In the following image, I made the surfaces translucent so you could see the guide curves, which are orange. Again, select the circles in similar locations to avoid twisting about the guide.

Hope this helps.

CFDruss,
In addition to Cowski & Tim's valuable input, if your circles are coaxial, you can simply create a cone (Form Feature->Cone->Two Coaxial Arcs.) This saves a couple steps if you have a straight guide path and won't need to modify tapers later.
