vector extraction with regions

[zetadierre]

Good morning!

I'm working on a very wide vector, in which I identified project areas, which I highlighted with polylines that I assigned a filling. being only these areas the areas in which to do the surgery, I would like to create a temporary level that contains vector information only within them, so as to lighten the file. is there a command that, given certain areas defined by polyinees, maintaining the selection of them, allows to use that selection to erase items outside that selection, on a different level?

I've been a little twisted. to make me understand better, in mind ps, a reverse select and delete. But to define a selection with existing elements, in this case my regions. I attach a jpeg to make it clear what situation I am.

already we are.. how do I create with the parallel lines command a set of lines? in fact I can not create more than 1 than the second clik stops me the command... Can I give him a curved pattern?

Thank you.

Yes, you were a little twisted.
However, if I understand your intentions, you can create viewports with the polygons that enclose the regions you want to isolate.
For example, select the polygon that encloses the blue region. go the command creates viewport. asks if you want to create a sheet layer, tell him yes, and he takes you to the new layer with your viewport. from the info tip, edit the viewport, selecting the layers and classes you want in print.
I do.

So you say that if I select all the regions I'm interested in and do this, I would work on a wieport for the whole project part of the exam?

Please show me where the sheet layer is? language problems... ahhh the tower of babele.... :

the sheet layer, it would be the layers that vw generates when you create a viewport. Actually, you can also create a viewport on the work layer (design layer).
However, both viewports are very comfortable for the purposes of the layout and printing. you can add quotas and annotations, change to flight color and thickness of the nibs, etc. but it is not on the layer of imagination that you have to work. all that is design you have to draw it on the layers of work.
So for your work you have to understand if you just have to isolate the regions at the end of the layout, with viewports or if you want to select them individually and isolate them on a new layer.
I do.

Now it's clear. the sheet layer is nothing but the "presentation layer", where I go to create the viewport. my problem, being of an operating character and not of a pagination, is not to get a wieport of the things that interest me (for that it seems to me that you only have to turn off the display of the other categories \lucidi) but to delete as if I used the rubber instrument with deletion of elements outside the selection. Here... I want to delete elements on the pippo layer that are out of the category duck. but duck is in the duck layer and not in the pippo layer. ;-)

at view level you can do it with viewports. in the sense that what is inside the polygon you see, the one outside not, being the polygon the crop window.
at operational level all selections with rubber - polygonal selection mode/external removal - recalculate the boundary range so that you eliminate everything that is outside.
I do.
