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?

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
I am trying to convince my mate he needs to move his Surly on to winter training duties and let me build him a frame.
