mass round edges

[Karol_Piroska]

I need to create a fairly complex curvy geodome like roof shape using mass and I came across a silly problem (something that should be very basic). Is there no other way to round edges of a mass other than creating void sweeps? I thought I did it previously, but that must had been in CAD.

Got pictures?

@barthbradley, it would be smilar to the one attached. It was supposed to be a few minutes work - L shaped mass box, round the edges, divide the surface, apply adaptive components etc etc ... and I couldnt believe I never came across the rounded edges issue (or should I buy stronger coffee?)

Easy. You can model it with 2 domes + 1 L (half circle profile) connecting the domes, join them.

Maybe contact the manufacturer, Geometrica?

@ToanDN 

The shape is a bit more organic than regular geometric solid swept and/or assembled.

I'm thinking of an imported NURBS surface for such an irregular surface.

thanks. 
yes, it is slightly more complex than interconnected domes. 

That image is from geometrica, but at this stage I need to produce it myself. I'll try loft between several profiles and if that doesnt work an imported surface could help, just not sure how it will behave in Revit.

I'm fairly certain that I could get there in the Conceptual Massing Environment.  Definitely not something I could just whip out in a few moments -- no matter how strong the coffee.

If it cannot be created from a composition of primitive forms then you can loft multiple horizontal profiles (layered cake), or vertical profiles (sliced bread).

@Karol_Piroska: Are you actually Planning its construction?  

[syman2000 · Accepted solution]

To construct that complex shape, you have use create reference plane and give it name

Place points on the ground level and use spline thru points

Go to profile, add points and then spline thru points

Once you have the profile, set it to reference line so the skeleton will be there once you create your form. As well I would spline thru points in opposite direction to create skeleton form below. Reason is if one side failed to create loft, the other side will able to create your form.

Once you create your shape, you can adjust your shape by  moving the point around

Then you divide your surface and now you can add adaptive pattern to your form

@syman2000 , thanks, that seems to be the best approach. Loft between several profile, adding profiles etc didnt work. 

[syman2000]

Revit can be very unperdictable with the profile. Sometimes you have to make it far apart and less angle. Once the loft shape is created, you can move it closer and it won't break. It is weirdest behavior I've encounter.
