Atom3D Q&A 2025

[DiogenesParticipant @diogenes]

..once I’d picked it up, I could not put it down again..

I’m still learning ‘The Principles’ by just playing – this isn’t part of a project – it’s an exercise..

Here is a fluted column. It’s a truncated cone, with 4 tapered cut-outs (‘windows’) disposed radially.

I’d like to ‘frame’ the windows, possibly with an ‘angle’ profile, but perhaps more easily with a ‘flat’ applied to the surface around each aperture.

Sweeping an angled strip around the inside ‘section’ of the cut-out is just do-able, but took several goes, made the processor ache – and the end result is unpleasing.

Q1 – how can I replicate this ‘sweep’ to the other three apertures

Q2 – I can see how a separate frame might be more pleasing – how would one form it – by building a ‘reference cone’?

Q1 – use a circular feature pattern.

Q2 – not sure I understand either your aim, or “reference cone”.

Q2 – How can I make a ‘frame-shaped-structure’ that conforms to the shape of the surface of a cone?

[David JuppParticipant @davidjupp51506]

Q2 – again not entirely sure what that means.  Is front of frame to be curved around the cone or flat?

I did draw a Williamson column at one time but can’t find it at the moment.

This is how I have done it with a plain cylinder in the past

1. Draw the shape of the window on one of the central planes and extrude it out beyond the cone. In your case I would just extrude out one sid eand then do a 4 x circular pattern of teh extrude.

Then cut off teh excess protrusion, I did it by cutting a “washer” shape along the length but if you do a shape with one line running parallel to the edge of your cone and do a revolve cut all the way round that will leave the window frame a set distance from the crest of the flutes

Lastly add any edge detail, I did a roundover

Then make it with a nice finish!

Just tried similar method on teh Otto Column
