Extracting edges from a polygon object

hi all,
is there the possibility to extract an edge (or a path of edges) from a polygon object to build a second object (for example the bonnet and the windshield of a car)
Thank you in advance

Sure...go to edge mode, select an edge, right click in the viewport, cover, then use the move tool to stretch out the edge into a plane. If you want that "extracted," then simply select the plane you just made, and do a split. Delete the original plane.
 
extracting edges

hi alvordr,
it's perfect for a simple situation, there are some problems with boolean operators. I'll try in a different way... then I'll tell you
thanks for your help :)
 
There's a good chance I'm not understanding what you're looking for. If you can throw up a visual, that may help.
 
Hi,

I'll add my question here as it seems related.

Is there an easy way to close the figure in the image, to add the missing surfaces. I did find the cover tool able to extract the selected surface but it is kind of hard to position the newly created surface.

Fill Hole works fine in some cases, Create Polygon seems the right choice for this particular task

cheers,

What works well and is pretty fast is to "cover" one edge and drag it to be visible. Then "weld" with set to "first point".

right, of course... and we should add that it was kind of hard to position the newly created surface: now with snapping turned on is a breeze
 
And I should add that you could cover multiple edges at once - but I didn´t get from the image which hole/s he wants to fill. :tongue:

Cheers

Thanks for all the help. I am trying to get my head around C3d by doing some easy modeling. The image shows what I was after. I ended up copying one of the surfaces and positioning it in the right spot. Repeating that for the others.

I will try your suggestions too. I don't mind doing it the less efficient way first, I am learning either way :)

So you deny effective solutions:
Make a parametric plane align to "Z" axis with 5 iterations for width&depth make editable - select all polys in one stroke that you don´t need - hit "backspace" - select all - call "Shell" tool set quantize to 0,2 - click&drag. :tongue:

Cheers

What I meant to say was, I will fiddle around till it works but I am eager to learn how it is done effectively. Meanwhile I do not see the time spent on the lesser effective way as time wasted. Like I said, I learn either way :)

I think C3d is a great program but there is a lot to learn before you can create something useful in just a few minutes. "Parametric plane aligned to Z" ... uhm ...

So I am not denying effective solutions... I just have to learn them yet :)

You are great at explaining, I am reading a lot, tutorials, answers to questions of which I don't even know what the question is :) But I hope to be able to contribute to the forum in the future, instead of asking questions.
