I didnt realise offset was for 2D. I will update my little black book. I must read up on the do’s and donts of offset, I am aware of its ease of ruination on surfaces, so prefer to use it on curves, sort out the mess then surface them.
If I project the simple line and arc shape onto my surface, then need to create a solid from that with its one surface 3mm offset inwards and its other surface 13mm inwards, how should I do that ? My instinct is to take the result of project and offset it inwards 3mm, then a further 10mm , surface them afterwards, but one mustnt use offset.
I had projected a simple line and arc shape that you see here to the surface, then as it developed measles, I tidied it up with FitCrv, as FitCrv doesnt alter the curves shape as Rebuild can, I am always after keeping the exact shape within tolerance if poss.
Then I surfaced it following all dos and donts learnt from here.
then I offset it and it went well.
Needing to offset it a further 3mm I thought I would use the curve again.
I threw rebuild at this just to see if it solved the squiggles, I also looked at Curve graph, so its a lost cause, because its 2D…
As I discover what shouldnt be used, I remember such, …forming quite a list in fact.
