Love answering stuff. No worries.
CAD modelling and rendering is a part of my process. Aesthetics are important to me and I feel I can guage the outcome much better being able to view my work as a visualisation render before committing to anything.
I also expect this will be my thing compared to other framebuilders. Customer will get a pretty precise idea of what they are getting.
Wheels are off Grab CAD website but everything else I draw up in Rhino. Dropouts and stuff for CNC machining I model in Fusion 360.All tubes are drawn up based on Columbus and Reynolds drawings if they are special (s bend stays for example) or I need to check clearances. So that top tube for example is a Columbus Max modelled after a drawing.
I draw tubes up uncut and have an archive of modelled tubes so it's easy to make a bike design by importing tubes and placing according to geometry line drawing
Hulsroy-
Are you planning to move your workflow to Fusion 360 entirely?
I appreciate there'll be a learning curve to drawing the tube profiles, but I think it would simplify your workflow keeping it all in one software suite. -
Really interesting, thanks. I haven't used Rhino since I had access via an old job. Might be able to get it through my University...
I'm saying this as an engineer who is shortly going to take a framebuilding class. I've previously figured out my geometry with the free version of bikecad. However it would be interesting to take this a bit further.By the by, I thought I remembered seeing similar pre-production renders (or actually hand-drawn art) by Tomii Cycles, but I'm struggling to find an example now so perhaps I misremembered.

s bend stays for example
what's your process? Bend, flow along curve, something else?
I've found my results to be somewhat unreliable.

Hope you don't mind the questions but I was thinking about this the other day.
These renders look great. Apart from visuals, do they offer any benefit?
Presumably you are modelling the frame and components in some 3D/ CAD software - which one? And do you need to manually define and extrude all the tube sections, or can you import geometries from catalogs?
And also, that top tube - off the shelf or custom formed?
