Problem making a blend form

[MVE1112]

Hello,

I am trying to make a blend kind of as shown in the picture.

The problem is as you see that i used a circle as base because i need it to be evenly shaped(?).

The problem is that when i cut the excess blend with a void the thickness at the edges is different from the thickness at the corners.

When i draw the base with the same form as the structure underneath, revit models the blend with lines in it and i need it to be formed as my picture.

I hope this wasnt too vague.

To be honest, I don't know what you exactly want to achieve. Could you explain it by a sketch or something?

What you are looking at is a square concrete column, and the blend form on top of that is concrete since the column cant have a flat surface because rainwater needs to run off it.

So to do that you slap concrete on it that has a thickness of 15 mm in the center and a thickness of zero at all the egdes.

If i draw the base the same way as the column i get 'folding lines' and i cant have that, so i used a circle but as you can see in the original picture: Where it says Void extrusion, the thickness is no where near zero.

So basically what i am saying, i need revit to form a rounded of form while having a square base.

As I understand you well ,you want to cap a column top with a sloped- curved surface..

I've made two screencasts showing how I see the problem solved:

1. using Component Model In Place
2. or using Conceptual Mass
