Hi Pilou, you don't have to only click on curves individually - just use window select to grab many things all in one action, like this:



For a case like this when there isn't anything else in the model you can also use Ctrl+A or also in other cases using the Scene Browser Types section can be useful for selecting all objects of a certain type.

But often times if you have a lot of things in one area, just using a window selection as shown above can save a lot of clicks! :)

Yes but for the last file given by Tony 77 (Wireframe) it was not possible without some manipulations :)
There were "internal edges"
Or I miss something : does exist External selection ?
Loop selection don't work in this case!

Hi Pilou - when I open up Wireframe.3dm from above I get the image shown in the above screen capture with just the outline wire... Do you see something different?

The other file Roof.3dm file has more stuff in it.

Sorry it was the wireframe3.3 not the last ! post # 8

Hi Pilou, I see... But you still don't necessarily have to do individual clicks - instead you can hide things that are getting in your way.

Go to the scene browser Types section and click on the eye for "Surfaces" to hide all the surface pieces in 1 click.

Then after that, a few crossing window selections like this:



Now you can hide those and then you have just the outline that you want to work with showing, or you can also invert the selection. But if stuff is getting in your way you should generally try to hide it earlier in the process as you are working.

Note that for those window selects I'm doing a "crossing" selection, where it starts on the right and drags towards the left. That kind of dragging selects any object that touches it in any way, if you start on the left and drag towards the right it only captures things completely inside the window. The crossing rectangle (right to left one) is shown with a dashed border instead of a solid border.


Also if you know that you are going to want to make a joined outer ring of lines, it's good to just do that during the earlier stages of the model like in that previous Wireframe.3dm file, before you even add the other internal stuff.

Yes the dashed box selection is good for that :)
And the Browser makes miracle's selections!
