Nedd suggestion on solid modelling

[Berserk]

Hello,

I am using UGNX5. I would like to create a solid body between the two existing one's and it should be at least tangent to both bodies.

The existing bodies were created with one extruded normal to arc with a 20 degree draft. The other was extruded along z-axis with a 10 degree draft. I need to fill up the middle.

If someone could provide a suggestion on how to model this quickly because I have hundreds of them to do.

Thanks very much!

I tried this one but the middle solid is not exactly tangent.

Here is another one that I came up with, but it takes a lot of time. I create lines and ruled surfaces and sew them together.

How about this. Not the prettiest way I'm sure but it doesn't look bad and it is using the KISS method.

You're on the right track, but you need to leverage your first models a little better. Look at this solution and see if it works better. Note that if you had made the first arc a sketch, this whole thing would be parametric.

Bersek,

I looked at your model3 and found it was 5 degrees out of tangency, so I have set about correcting it as an exercise.

Okay I worked what you problem was and created a model that should help to solve your dilemma. The blue curves are extract isoparametric curves. Notice that the point where they meet is not at the ends of the bisector line as we may all have initially assumed that it would be.

The sketch is just for effect because that construction method is rather easy to follow. I have used a slightly different extrude until extended method to eliminate the replace face that you used earlier. If you analyse it carefully, while I have used through curves instead of ruled, I have done so in a quite equivalent manner without attempting to force any tangency. When checked however you will find the tangency is quite good. I guess you could say that you know that you have the right construction geometry when this occurs.

This is a common feature in some moulded parts and a good reason why it would be nice to have associative isoparametric curves in some future release.

Okay here's one for the well constructed CAD models III.

For this simple case only curves equivalent to the isoparametric curves I extracted earlier can be derived from judiciously places datum planes. Since everything is now associative try changing the diameter of the arc curve from 20 to 15 or 25 and you'll see the result.
