There is an ascii notation for this, its called SVG. QCAD already handles a subset of known entities.

When I double click a DWG file in windows explorer, most of the time, a new instance of QCAD starts. I would rather have the file opened as a new tab in an already running instance of QCAD, or, if the file is already open, have it focussed. This is on windows 7, RC5. Curiously, this behaviour is inc...

I found the time to look at how Adobe Illustrator handles grouping and layering. It also has a tree view of the drawing's entities, similar to Inkscape's XML view. And just the same, groups are nodes below layers. Grouping of entities on different layers will put the group into one layer. Exploding ...

No, it is not the domain name, I do browse ribbonsoft.com/rsforum. Its that I am slow at writing. I sometimes have to verify something, that I am about to post, before submitting, eg. by running qcad and producing a screenshot. I learned that the timeout should default to 3600 seconds. But after 20 ...

The forum software times out logins too quickly. It happens to me e.g. when composing a topic reply. I always have to copy the post before hitting preview/submit, so its not lost (or have to hopefully find it in browser history) or hit preview occasionally, to keep the login alive.

May I chime in? I had the same problem yesterday: inpsired by the screenshot on the blog, I created an isometric view of a part. Circles in my top/front/left view would end up as ellipses there. I found the scissors remove segment D2 operation very convenient to yank hidden lines. But it would occas...

Sorry for bringing bad news. I now read http://wiki.inkscape.org/wiki/index.php/DocumentLayers and there also is no indication that this is a known deficiency of inkscapes interpretation of what SVG can be taught to. Instead it says there, that Adobe Illustrator uses the same concepts, and the adobe...

I did a quick check with inkscape: when I group two objects, that are in different so called "layers", the group will then become part of the upper "layer". "layer" information of the objects themselves is lost by grouping them. This is an irreversible action. Exploding the group will put all the me...

There may be programs to directly get you wmf from cad. Not that I know of though. There are several to get you wmf from svg. QCAD dwg/dxf CAD to SVG conversion is best of breed. UniConverter should be as good as you can get for wmf creation. For download and usage instructions refer to http://www.s...

PNG is not designed to represent real world objects in any other sense, than what they look like. It is not designed to perform measurements of such objects. PNG is a bitmap graphics format. A bitmap is a matrix of X by Y pixels. A pixel is not a physical unit. There is one anchor into the physical ...

Thank You Andrew for the advice. I immediately changed my scripts to destroy any or most of the documentInterfaces created and let it run. I have not taken notes before, only account from my memory, but the savings are worth it. Hundreds of MB turned into tens, whith close to 1000 drawings created.

Thank You Andrew, with this information I started to refactor. I nearly gave in, as everything would end up in the same layer. But now it works :) var operation = new RAddObjectsOperation(false); // not undo-able document.setCurrentLayer("A"); // […] create some entity operation.addObject(entity, fa...

Seems I am a little confused by RAddObjectsOperation and RAddObjectOperation. In fact I only use the first plural one and never the second singular one. These operations I call from helper functions, that draw geometric primitives, that create both operation and objects internally only. var operatio...

In my scripts I add objects one primitive by one primitive. They execute quite fast. Still I want to ask: For performance reasons, can one join several RAddObject Operations into one RAddObjects Operation? When I switch layers inbetween those, will the entities end up in the right ones then? Or does...

This is with a Ubuntu 10.04. bash version is 4.1.5. The startupscript works flawlessly. Eg qcad -style motif tests OK. I also use it to run autostart scripts. Curiously, here now pure qcad-bin (RC2) does not crash with the default theme, as it did half a year ago. This is not a gnome desktop, but an...
