Set relative zero point tool.

Implement layer locking

Implement isometric projection tool

In files exported with the (even PG) exporter I sometimes see values like these: 334.99999999999994 or 570.0000000000001 and very often 12 digits of precision.

To safe on file size, I suggest, that QCAD rounds values on SVG export to eg. three places. When viewed in an ordinary web browser, that will result in a precision of 1 inch / 96dpi / 1000 = 0.00026mm, not? Ends should still meet.

If I understand correctly, SVG export uses svg groups to keep QCAD block entities. This in itself is very useful. There is no way to correctly keep layer information, as QCAD blocks can contain elements on different layers, while SVG only knows about groups. That is a deficiency of SVG.

To save on file size, there was some potential to get rid of ever repeating same attributes on entities, eg: style=”stroke:#000000;stroke-width:0.25;stroke-dasharray:2.16,1.08”

To optimize “By Block” is easy: just set the attribute on the SVG group, and omit on below entities styled “By Block”.

To optimize “By Layer” is a little more involved, but might be solved by using css:
- Create a class by the name of the Layer
- add the class attribute to elements styled “By Layer”

Then only individually styled entities would get a style attribute, and filesize of SVG could be halved in most cases.

This just an idea :) Having written this, I now realize, that QCAD can style weight, pattern, color each extra, so the optimazition could only be applied to entities, where everything is “By Layer” or “By Block”. But that should be the case most of the time.

Line type rendering with drawing unit != mm

Arcs rendered with QPainterPath::arcTo are not precise. Especially the start- / end point offsets are confusing. Differences are up to 0.01 units.

Limit preview shapes / entities by user configurable number

Explode blocks

add parameter to REntity::clone to allow cloning without cloning object ID.

Hi, I open a drawing with Qcad2 and:
- The hatch angle is changed
- The linetype is continuos for all lines
- The “white paper” in print view not show

I add a screenshot

Make grid configurable.
Switch on / off grid visibility.

Dimension labels in QCAD are (always?) centered on the dimension line, while in exported SVGs the text starts from the center and extends into the writing direction. This can trivially be fixed by adding the attribute “text-anchor:middle” to the respective SVG “text” nodes.

QCAD offers horizontal and vertical alignment choices for text. This is not carried over to PG exported SVGs. Currently QCAD sets the “dy” attribute on text nodes in a way, such that any text in SVG will look like the QCAD vertical alignment was set to “Top” and the horizontal one to “Left”.

Naively one can just omit the “dy” attribute and in SVG this will look like the QCAD vertical alignment was set to “bottom”. At least for single line texts that should be good.

The horizontal alignments can be recreated in SVG with the “text-anchor” attribute for text nodes. The values “start”, “middle” and “end” correspond to the QCAD “left”, “center” and “right” choices.

When PG exporting to SVG, stroke-widths are scaled with the drawing, while they should not.

The SVG PG exporter does not scale hatches.

Text scaling in PG SVG exporter is missing just two small additions: These attributes are not taken care of by now:

font-size, dy

Just use the current value times scale: eg 2.5 * 0.1 to have a scale of 1:10. Looks good here.

Points are not scaled when PG exported to SVG:

Points as crosses are created eg. like this:

d=m 2.5,3 1,0 M 3,2.5 l 0,1

and in SVG look fine like that (scale 1/10):

d=m 2.95,3 0.1,0 M 3,2.95 3,3.05

stroke-width should be left unchanged.

I’ve looked high and low and cannot find how the the Status Bar is toggled on/off as in QCAD2

SVG PG exporter, scaled or unscaled, currently only exports the labels of dimensions. Missing are

ticks, arrows, and lines of the dimension.

It will not be as simple as inkscape does it, wrap it all in a <def>.

In print preview lines are correctly scaled to stay the same width when printed, ie 0.25 or so mm thick. Print preview shows that very good.

But the round line-caps mess up the display, as in small scale the line-caps start to meet and make the line look like a continous one.

Print preview should not only correct line weight but also line patterns, so that the distance between dashes increase by scale.

Cannot move/dock command line to right hand pane!

White text gets exported as white text, while it should be exported as black text. Just like it is with lines. Attached patch makes text rendering use the conversion function that is already in the code base.

Font styles “bold” and “italic” are not saved to file.

According to http://docs.autodesk.com/ACD/2011/DEU/filesDXF/WS1a9193826455f5ff18cb41610ec0a2e719-7a4d.htm it is saved in dxf as group code 1071 and according to http://www.autodesk.com/techpubs/autocad/dxf/dxf2002.pdf page 20 its type is “Extended data 32-bit signed long”.
