Is there a bug ???

I'm totally newby, so I may commit mistake, but I can't understand what happens : in the current drawing, I create a new layer, view it and select it, then I try to import a dxf file : it comes into layer 0 !

Sometimes, after "I-can't-remember-what" operation, some entities can be visible only if two layers are visible : they desapear if either layer (or two) are not visible.

Can anybody explain that (LibreCAD V2.0.0Beta1 Oct 29 2012)

Hello Yves,

Not a bug.
When you import a dxf into another dxf you are appended it as block (File->import->Block)
and all imported entities maintain their properties (color, linetype, layer, etc.)

The "two layers" case are related to Blocks and Inserts, and neither is a bug.

To better understand the operation of blocks see these threads:

Thank's Rallaz. It's very kind of you to answair so much basic and recurrent questions.

In fact, the most difficult thing to learn with a new program is it's ergonomy, and I have much trouble with it !

At the moment, I will try not to use blocks, that I do not understand enough. And I have other problems...

At a moment, I had to draw a line "with two points" (a segment), and it worked well. Then I try again (in the meantime I went to some snap restrictions, but there are no more). I indicate the first point, then the second, and the machine draws the whole line ! I ask again my question : "Is there a bug ?"

Thank's again.

LibreCAD has bugs, of course, but you have not found none yet
When you set a layer not printable (print icon in layer list) are converted as "auxiliary layer" and lines
are drawn infinite. Check by click in "print icon"

Once again, thank you very much. I'm affraid I'll ask a lot of questions till I'm "fluent" with LibreCAD.

I have also to become "fluent" with forum.libreCAG.org... I was frustrated not to view my avatar... Hope I understood now

Arrhhh ! Of course, I don't think it's a bug... but I don't understand why some layers get unwillingly the "Help layer" attribute.

And I have a layer on which I imported a drawing (JPEG), and I copy some lines of the drawings as polylines on other layers. Sometimes, those "other layers" seem to be "under" the drawing, and so I can't see them (obviously, the corresponding layers are supposed to be visible, and I see them if I make the drawing layer invisible).

Thanks for patience.

Ok This at last found a bug... but late
Seems you have foud the same bug as ePoxi user in this thead:
http://forum.librecad.org/Lines-went-to-infinity-td5707037.html

If it is the same, are solved, but you can wait for next windows relsease: beta2 or RC1

About using JPEG the layer order are not relevant on paint screen. You use "Edit->draw order"
submenu to move image to bottom

OK, I'll wait for Beta2. Is it schedulled ?

But I asked for two things : The question of draw order. I could'nt find again then phenomenon. At the first occasion, I'll test "Draw order"

Thanks again and again.

Beta2 will be published shortly but there is no date yet.
You can use this file (only uncompress and use)
http://sourceforge.net/projects/rallaz.u/files/librecad-win/librecad2.0.0beta1-git2013-04-16.7z/download

About "Edit->draw order" is menu "Edit", submenu "draw order" then "move to bottom" the JPEG image
