QCAD Bugtracker

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.

1. new drawing
2. tools → circle
3. click center → crash

source code segment:

void RGraphicsSceneQt::exportArcSegment(const RArc& arc) {
    RPainterPath& path = draftMode ? currentPainterPathDraft : currentPainterPath;
 
    // try QPainterPath arcTo method first but this can be very
    // inaccurate (+/- 0.01 difference from start- / end point):
    RPainterPath p;
    RBox box(arc.center - RVector(arc.radius, arc.radius), arc.center
            + RVector(arc.radius, arc.radius));
    p.moveTo(arc.getStartPoint());
    p.arcTo(box.toQRectF(), 360 - RMath::rad2deg(
            arc.startAngle), -RMath::rad2deg(arc.getSweep()));
=>  QPainterPath::Element e1 = p.elementAt(1);
    double errorStart = RVector(e1.x, e1.y).getDistanceTo(arc.getStartPoint());
    QPointF ep = p.pointAtPercent(1.0);
    double errorEnd = RVector(ep.x(), ep.y()).getDistanceTo(arc.getEndPoint());
 
    if (errorStart<1.0e-5 && errorEnd<1.0e-5) {
        // TODO: check if this is ever reached:
        path.addPath(p);
        return;
    }

the buttons works, but are not toggled (”restriction off” is always pushed)

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

Greetings

When I save a view for print i like that wiew remember the layers open and closed.

This feature could be improved with remember print scale, dimension text size and page size

Make grid configurable.
Switch on / off grid visibility.
