Extrude profile to profile

2 faces + Path? by Kirill2008

No disrespect intended, but couldn´t you just push/pull that and scale the upper face subsequently? Those faces are the same shape, right? Am I missing something?

Thank you very much for exhaustive explanation!

@Tig

great plug in you rule guy !

Yes you can - unless one profile is not quite the same "shape"...

Bingo!

Yeah, that is what confuses me - I was sure arcano´s profiles were the same shape, only different in size.
Anyway, some practice with your extrude tools won´t hurt - they are indispensable, especially when it comes to creating complex shapes.

don't thank me as all I've learnt I gotten here and continue to learn more everyday. For most problems there's many approaches so everyone has given good pointers.

Have a good one

I would like to know why you divided the line before welding. The link you give is to the smustard site and I see no answer for the question there.

Cheers

Hi,

TIG's example are exactly what you need and unfortunately he beat me to the punch but here's a little info anyway....

You'll find the 'Weld' plugin here

This shape could have easily been created using EEbyFaces with a lot less click but this might help you understand how the Extrude Toolset works.

If you wan to know why i 'Divided' the line before welding read this

Post your models if you can or if your stuck!

[TIG]

I think he meant "how" [to get 'weld.rb'], not "why" [he divided the edge before welding its parts]...
To use the EEby... tools [and others] any profiles/rails/etc need to be 'curves' - that is any collection of edges that have been made into a 'polyline' [in CAD-terms] - or a 'curve' in SUp-speak - SUp's arcs etc are naturally 'curves' - Bezier curves etc made with Fredo's tools are also this type of 'curve' - BUT any edges joined end-to-end [with no branching] can be made into such a 'curve' - even if there is no apparent 'curviness' in it at all
The tool to make these edges into a 'curve' is weld.rb. However, you can only 'weld' two or more edges into a curve, if you have just the one edge then it can't become a curve that way - therefore select the lone edge, right-click context-menu > divide it [i.e. 2 or more - if it's to match a 'paired' curve as a profile/rail/etc then it's recommended that you divide it to have a matching number of segments], it will remains highlighted [but it's now in bits], immediately weld those selected bits into a curve...
You are now ready for he next step...
