Given: Template with prepared Paper Space Frame/Titleblock scale = 1:1.
Drawing 1:1
First Viewport / scale 1:1 / inserted in Paper Space = everything fine,
Second Viewport / scale 0.02 will scale the Paper respective to the new Viewport scale but the Frame/Titleblock isn’t scaled.

it’s not true !!!!!!

My request it’s not implemented !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Task:
I like to draw a line tangent between two circle.

I choose the line/tangent tool - click the first circle - get a Warning Message: “No tangent possible” confirm the Message with the OK Button.
Choose the second circle - get again a Warning Message: “No tangent possible” confirm also this Message with the OK Button.

Result: A line tangent between two circle ......

Tab value specification in Option bar: Lengths 2, Thickness 1
G-code Lengths = 8.35 (in my example), Thickness 1

When using (adding a TAB on a radius fails).

Example:

When length of the TAB is set to 1 mm.

After export to *.nc code the code is not ok.

And then check this is NC viewer or gcode sender the length is not set to 1 mm but is smaller.

On a line this function (TAB) is correct working.

Win7pro 32bit Wininstaller Qcadpro 3.23.0

Draw an arc.
Select the arc.
In Property Editor:
Set start angle to 135
Set end angle to 135

SweepAngle = */-360

edit the end angle and add “+360”, hit enter

SweepAngle = 0

An arc with zero sweep is a point.
A point is not an arc.
With the same start and end parameter an arc should have a sweep of +/-360.
As for entries by points or by angles.

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.

With the 3.0.3 point release (latest available for Linux systems), SVG PG exporter fails to export splines:

Uncaught exception at /opt/qcad-3.0.3-prof-linux-x86/scripts/ImportExport/SvgExporter/SvgExporterPG.js:72: TypeError: Result of expression ‘splineSeg.getDegree’ [undefined] is not a function.
72 var degree = splineSeg.getDegree();

The objects returned from getBezierSegments() do not provide the methods of RSpline.

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.

The SVG PG exporter does not scale hatches.

Patch to PG export font styles “bold” and “italic” to SVG. (This only works when a file with the right style is loaded into QCAD, as QCAD will yank such style information upon saving.)

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.

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>.

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.

A hatch my have “holes”, if it eg. is made of two forms, an inner form, and and outer form, where the outer form is filled while the inner form appears like a window inside of the fill, that lets the background be seen.

QCAD exports such hatches as two SVG paths in one single entity. But the “hole” is lost in the process. I know of two workarounds, that preserve the original intention of the QCAD drawing, both get the same result most of the time, the second one looking more robust and easier to implement:

# draw the outer form clockwise, draw the inner form counterclockwise
# set the “fill-rule:evenodd” attribute on the fill definition of the entity

Drawing a star like in the SVG spec in QCAD actually produces the same picture – so that should be the way to go.

http://www.w3.org/TR/SVG/painting.html#FillRuleProperty

importing a svg generated by inkscape from a downloaded eps results in all contained arcs drawn in wrong direction

(I’m running on FreeBSD, but that was not an option in the selection for Operating System)

When importing a SVG file in version 3.7.5, it qcad turns polylines into polygons.

I’m attaching a trivial .SVG file showing this, it should *not* render as a rectangle,
but as a “rectangular upper case C”.

And many thanks for making good quality CAD software available to the FOSS community.

I noticed, that paths are not fully imported into QCAD. I rewrote case “m” of “SvgImporter” like below, that way also straight line segments are drawn correctly. Case “M” should be similar:

      case 'm':
          x = ox = coords[0];
          y = oy = coords[1];
          x0 = x;
          y0 = y;
          for (k=2; k<coords.length; k+=2) {
              x += coords[k+0];
              y += coords[k+1];
              this.importLine(ox, oy, x, y);
              ox = x;
              oy = y;
          }
          break;

Attached sample drawing, that kills QCAD 3.1 beta when exporting to SVG.

The crash happens in line 38 of SvgExporterPG in function SvgExporterPG.prototype.exportPolyline

var pp = new RPainterPath(polyline.toPainterPath());

Hi,

when I export a dxf draw to svg the text objects shows in a bit different place.

QCAD version is 3.21.3.14

When exporting a drawing to SVG, polygons containing arcs (trimmed circles in this case) are converted to straight lines. If the polygon is exploded first, then it exports correctly. Of course, this isn’t useful if closed polygons are required for the program using the SVG file. Solid hatch fills export correctly. See attached DXF and corresponding SVG export.

https://qcad.org/rsforum/viewtopic.php?f=33&t=9731

Quick SVG export of a block reference can lead to unexpected results if the vertical flip option is enabled during the insertion of the block. See above forum thread.

Both SvgExporters ignore the exportPoints setting. Attached patch takes care of that. To be applied from within the “scripts” directory.

Nitpicking in File/SvgExport/SvgExport.js, var properties is meant to be a plain Object instead of an Array, isn’t it?

The SvgExporter opens a “group” for some entities, but never closes that group. The resulting nesting can get quite deep and does not conform to the original. I tentatively patched the script as below:

--- SvgExporter.js-orig	2011-05-23 10:55:17.239998578 +0200
+++ SvgExporter.js	2011-05-23 10:55:17.239998578 +0200

 SvgExporter.prototype.endEntity = function() {

There might be a better way, but that is what I came up with on short notice.

Quick SVG Export suggests file name “Untitled 1 [*].svg”

Remove [*] (comes from window title).

Points in hatch patterns are exported as empty path elements in the exported SVG.
Therefore, the hatch patterns “DOTS” and “AR-SAND” are not visible in the exported SVG.

E.g. if a block reference has its color set to ‘red’ and the block reference has an attribute with color=’ByBlock’, the attribute should be displayed in red.

I very much like the new middle mouse button zoom in/out and congratulate Andrew for implementing it so quickly but there’s an annoying delay that is necessary between successive zoom in/out actions. This is easily understood by comparing it to zooming in/out with the +/- keys. With the keyboard you can repeat zooms as quickly as the keyboard repeat rate allows; with the middle mouse button quick zooms are not possible.

Draw a horizontal dimension. Stretch (S S) it. The label remains in place. It should instead go to the new center. (Unless it was manually positioned perhaps...)

Workaround: Pick one extension and drop it to where it was, label gets centered.

Stretching hatch entities results in broken hatches.
Regression introduced in QCAD 3.1.5, bug still present in 3.2.2.

hello. if i use the tool on my own drawing, no problem, but on an element coming from the library, the blue selection square appears, it moves but the chosen shape doesn’t follow. i’ve tested several ways and even by creating a block. cordially

bonjour. si j’utilise l’outil sur mes propre dessin, aucun Souci, mais sur un élément de venant de la bibliothèque, le carre de sélection bleu apparait, ce déplace mais la forme choisi ne suis pas. j’ai teste plusieurs manière et même en créant un bloc. cordialement

The stretch function does not work at all. I tried it in the old version 2.2.2 where it worked.

Test case:

In Windows, set up say 2 or 3 new blank drawings.Then close them down one by one and notice the behavior when closing these drawing windows down!

Status change for Visibility is without any effect on Viewports in Paper_Space.

Case:
Entities drawn on a layer in Model_Space. Visibility on/off works.
Situation covered with a Viewport, placed in Paper_Space, Edit content launched for that Paper_Space, Visibility on/off doesn’t works.

It was properly working in previos QCAD versions ...

Please refer to topic: https://www.qcad.org/rsforum/viewtopic.php?f=33&t=8921

- Launch QCAD-Pro 3.26.4.13, Status Bar is off by default
- Set menu View > Status Bar on
- The Status Bar is showed but the menu options remains unchecked
- Quit QCAD-Pro
- At launch QCAD-Pro opens with the Status Bar toggled off
- Set View > Status Bar on (or issue GS from command line)
- At the next launch the Status Bar is off

Note: the preference StatusBar in the .ini file has the value “false” when it should be “true”. Changing the value manually to “true” makes the Status Bar appear just for the next launch of QCAD then the preference is reset to “false” by QCAD.

- Deleted the .ini file, same behavior
- Changed user, same behavior
- Tried on MacOS 10.11.6 (El Capitan), same behavior

Then QCAD exits (does not start). As far as I remember, 3.23.0.2 release was fine.

Having a multi selection and at least one ‘older’ arc the startpoint indication in red of some entities might disappear.

Entities that suffer from this are:
Other arcs
Polyline
Splines

Only the ‘oldest’ arc in selection will have a startpoit indication.
Multi selection of ‘newer’ entities from the list above will not if an ‘older’ arc is part of the selection.
Deselecting de ‘older’ arcs will reveal the startpoints up to the ‘oldest’ arc.

In the file provided entities where drew in order from left to right.
Select all and start deseleting arcs from the left.

The behaviour is affected by changing the draw order property and a save/close/open.
In the second file the rightmost arc was set to draw order 7, the same as the 4th was.
After save/close/open it is renumbered to 8 and the behaviour is different as in the firts file.

Hi,

If you open an old qcad drawing thats DXF and edit text, the popup window shows “Main Font” as empty.

If you do not set the font and complete the edit, it will change the font from the standard to what looks like an Arial font.

If you set the font as “standard” during the edit, each time in future you open the editor it does at least have standard selected.

Ie if no font is specified in drawing, should it not select “standard”?
