3D Fillet - Unsymmetrical Radius

[Mark Aceto]

Is there a way to create this filleted edge in 3D?

 

 

Client provided the 2D elevation. I'm trying to match that in 3D. I'm sure I could accomplish it with subdivision modeling but I'm trying to keep it simple for parametric editing as the design develops... 

 

The screenshot below is a 1" radius:

I think you'd have to start by making the pink part "taller" and with equal radius fillets, then using the Z scaling factor that solids have in the OIP to squish it. It'd just take some calculations ahead of time to figure out the correct pre-squished dimensions.

 

Another option would be to use an Extrude Along Path of the negative shape, then subtract that from a regular extrude.

Would this be useful? A script to convert 2d orthographic outlines into 3D solids. Great for someone like me who doesn’t do a whole lot of solids modelling.

Here's a file with two different approaches –

 

1. Approach one shrinks the base shape by 1" and adds the profiles using an Extrude Along Path. Vectorworks seems to struggle with this geometry and won't Add Solids cleanly at the end.
2. Approach two uses a second smaller extrude on top of the initial extrude that gets filleted and then squashed so its height is 5/8". It creates a clean solid addition. Note VW wouldn't initially do the 1" fillet on the small extrude. I had to use a smaller fillet dimension and then change it to 1" later in the OIP.

Hope this helps with some options. These are pretty common and basic shapes. I'm sort of sad that VW struggles so much with this. @JuanP the development team should try out this task 🙂

Worked like a charm--thanks!

 

Increased the extrude (solid) from 4" to 6 3/8"

 

 

 

Then scaled the fillet Z by 0.625 (5/8") which brought the height back down to a squished 4"

 

 

I'm sure this design will develop but it feels great to deliver a 3D model precisely as spec'd by the client.

 

That said, echoing @Kevin McAllister that I was expecting, and am still hoping for fillet controls similar to the Round Rectangle tool...
