Defective Revit blend

[Prvoime]

Every single person who made a tutorial about modeling in Revit shows this example. Rectangle on the bottom, circle on the top, and there it is.

And not one single person addresses the issue of what we get as a result. Pretty messed up object with two completely flat surfaces. It's even on the icon!

Now compare that to the same thing done in 3dsmax. Smooth, seamless, gradual transition from one shape to another.

I admit I don't actually need this in Revit right now. I just find it curious, did anyone ever need to make this shape in Revit, how do you solve the issue of nasty triangles?

  The trick is to have a blend 1 to 1 line to get this work. If you have 8 base lines and 1 for the circle, you will get a defective blend. If you break up the circle into the same number for the base, you will get a perfect blend.

Awesome, thanks for the explanation.

This example is shown in every single instruction about modeling in Revit that has been created. There it is, rectangle on the bottom, circular on top.

And not a single one talks about the problem of what we end up with as a consequence. An odd device having two perfectly smooth surfaces. It's on the icon, too!

Now contrast it with the same project completed in 3dsmax. Gradual change in shape that is smooth and seamless.
