Limits to QCAD before it crashes

Hello all,

My QCAD (3.4.6 PRO) running on Windows 7 (SP1, 64 Bit, 4 GB RAM) crashes rather frequently. This mostly happens when I am moving large amounts of objects or even a few Hatches around in the drawing.
Is QCAD not meant for this stuff?

For example, in order to have the borders of structural objects shown above the hatches (which are used to color code them), I tried cut+pasting them so the draw order would be later and the lines would show on the hatch and not vice versa. Image linking did not work although there is a URL option above! If you care, it is on tinypic.com/r/14mx9pt/8
However simply 'cutting with reference' 448 entities (each of which is the same block) causes my QCAD to crash. And also crash so bad that it can't manage an Autosave or remember it crashed the last time when it restarts :(

Am I pushing my luck using this software or is there hope? The performance monitor I ran during the last crash showed I was on 50% Memory usage (but 112% frequency) if that helps.

Appreciate any help. Thank you, kind people.
Frig

My apologies, this is a measure to prevent spam. Note that you can simply attach images to your post directly ("Upload attachment" below post form).

Thanks for your report.
Could you please attach or e-mail your drawing file, so we can try to reproduce the problem here and fix it? Thanks.
As an immediate workaround, you might want to use the move tool instead (Modify > Move).
And also crash so bad that it can't manage an Autosave or remember it crashed the last time when it restarts :(
Autosave is triggered automatically in intervals configurable in Edit > Application Preferences > Load/Save > Autosave

Hi frigitar and welcome

Out of interest what type of drawing are you having these issues with - Architectural, Mechanical or other ?

Thanks for the replies.

I'll send you, Andrew, the file so you can reproduce the problem - its not fun though. Modify move works fine but I wanted to 'recreate' these items so that the draw order is after the hatches I already have on there. With a later draw order, I would hope that they would be drawn on top. Hence I wanted to go the cut + paste route. Any other way I can change the draw order? I read on another thread that this option does not exist on QCAD as its not seen as important to CAD principles or something like that... e_ugeek

@Clive : Thanks - Yes its rather Architectural I would say, if at all. But its just basic drafting really. A bunch of blocks as you can see in the image I linked to. It could be anything - a floor plan, a plan for a hall or as in my case an outdoor plant site plan.
But yeah the drawing spans out over about 100x200 meters, if that is important.

You can move entities to the front with Modify > Bring to Front. Alternatively, you may use the property editor (View > Property Editor) to change the property 'Draw Order' of the current selection. Entities are drawn in the same order as this value. I.e. The higher the value, the more on top the entities are.

Thanks for the file, frig.

I am able to reproduce the problem here with QCAD 3.4.6 on all platforms.

The problem is caused by reported bug #1032 (http://www.qcad.org/bugtracker/index.ph ... sk_id=1032). This has already been fixed for the upcoming 3.4.7 release.

The best workaround for your situation is:
- Right-click on block 'Table 12' and choose 'Select Block References'
- Modify > Bring to Front

Ah there is a draw order option! Sweeeet.
Helpful. Thanks.

Glad the other issue's been solved.

Sorry I have a follow up question. Is there a shortcut to bring up the property editor? Or a way to have it float in a small minimised icon (like in autocad) when an item is selected so that it can be clicked and expanded? Or a button on the toolbar?

Right now, I click on an object, go to view>toolbars>property editor , which is too long ... also I don't want to have the property editor as a fixed pane since it considerably decreases my workspace.

GP (see also menu which lists all the key codes)

Meanwhile QCAD 3.4.7 has been released which fixes the problem with cut/copy/paste and block references.
