Filleting Corners

Dear master

There is a question:

Aside from your other professional techniques and experiences for creating such excellent engineering work, how do you created those neat complex fillets without any defect in the corners?

Is there any instruction or guidance that I can follow it?

sure

first you need to be mindful how you build things and it starts with the curves.

second i always use “blend edge” command because i think it produces different results than fillet command and to me it looks much nicer

i exploded this just to show you some parts it is easier to blend like this than having everything joined toghether rhinos blends have become better since i upgraded from v5, which means i am able to produce smooth things like this faster without fail

i always use “distbetweenrails” option because they produce straight blends looks better than rolling ball but you will have to experiment what fits you

learned this from the R8 bible but kyle Houchens from mcneel has a video called “pipe trim trick” which is the same https://www.youtube.com/watch?v=4mXv4IaWSBw
i use this one when blends cant be produced correctly or satisfied a nice workaround which requires a bit more work but the results are good

then i use “show edges” and zebra command to check the results

and the most important part: always check your work before you move on, different viewports, render, shaded etc…

there are problably more techniques out there but this is what i use

Thank you so much for the explanations, and also thanks for senior Kyle for offering the trick!

Does blend works for intersect edges (perpendicular to each other)?

Also, I didn’t find " distance between rails " command in Rhino 7

can you show an image or file with an example? It comes back to how you build things first

When you run the blend or fillet command you find this by the command window up top by default it’s “rolling ball”

I meant, isn’t there any deformation at the corners?

This happens when you select all edges unfortunately I’m not technical enough to explain what happens under the hood in Rhino it just does this

You can take a square and select all edges makes the same result

Looks good enough to me saves time

Pipe trim trick always gives the best results but imagine if I did this to everything in the model I’d go even more nuts than I already am, it’s just to much work.

looks like this in shade if it gives more information

I used senior Kyle’s method, and I could get it (of course a simple one)

Nevertheless, it seems different with the piece you created in the corners. Yours seems like triple pipe.

I’ve moved this part to a new topic.

pipe trim trick does not produce like this

thanks gijs im sure someone else can explain better

@sciensman the corner type you find in Cadartz’ models is called a setback fillet.
This happens by default when using BlendEdge, (and is an option in FilletEdge in Rhino 9 WIP)

interesting i learned something new today

Master, CADARTZ

I’m embarrassed to have taken up your time, and interfered your expert topic.

Thank you for your mercy that despite being busy with this great job, answered my primitive questions patiently

Thank you a bunch :slight_smile:

So, it doesn’t exist in Rhino 7?

The type Cadartz is using, BlendEdge, with automatic setback, is part of Rhino 7
