Andrew,

Not OS or Version depending.

We can’t filter on some specific properties of polylines.

Handy would be:
- Global Width
- Orientation

Specific:
- Polyline Pattern
But I don’t really search for them ... For some post-op I just need them all to be set to ‘No’.
- # of vertices
Filtering the complex from the more simple ones.
- Including Bulges or not
To seperate polylines with arc segments form others.
There some operations that don’t really work with bulging.
- Z values and/or global Z
This would make sense for some but filtering on Z is not common under QCAD as it is 2D.

CVH

Andrew,

Changing orientation of a polyline with RV or by changing it in the Property Editor clears the global width value.

Single line pieces as polyline default to CCW.
Still the global width is cleared when trying to set them CW.

I didn’t update since 3.27.0 but reading this topic I suppose it still is valid.

Could we please implement the ability to display file contents in the file explorer. This would make it easier to decide which files to open.

How to reproduce the bug:
1-open a new file
2-select text tool, simple text(one line,no formatting) and alignment in base-left
3-write some text in somewhere position in the draw, repeat this in others positions
4-save the file in .dxf R15 [2000/LT2000] (dxflib) format
5-close Qcad
6-open the saved file, the writhed text lose original position and now all the text have 0,0 position

The tool “Clip to rectangle” / “Cut at Area Boundary” tool used on an area with lines and arcs will partly complete arcs to circles.

It might be useful to have the possibility to manage the references of the images contained within the drawing. A design could use recurring images, stored in a folder outside the one in which the design is located. Moving the drawing or folders (or changing the PC) will lose the folder references and the images are not displayed when the drawing is opened again.
I imagine the possibility to view the references of the images (and if necessary modify manually or with a pointer) with the option of: attach, detach, reload, etc., as in the example below (referred to ActCad - based on Intellicad technology)

QCAD (before version 3.27?) used to show some custom XDATA, e.g. tag 1000, even for application names that are not “QCAD”, which for me was useful, so it’s somewhat of a regression. (I think it was broken when selecting multiple items, maybe that’s why it was removed.)

I suggest to bring that feature back, but maybe show it only when a single element is selected if that’s easier.

(As a workaround/hack I guess it would be possible to rewrite the required information as QCAD compatible XDATA externally I guess.)

Headline should already explain the issue ...

Andrew,

In the attached dxf:
Besides that it is clear that duplicate vectors are not filtered ...
Where a segment is crossing in another node a non valid node is returned as self-intersection point.
Seems to be unrelated to CW/CCW or tolerance.

Where 2 nodes coexists 4 duplicate vectors are returned.

Hi,

I believe prior QCAD version 3.22.0.0 there was no rotating preview. The rotating preview shows the outcome regarding to the chosen center point. I know that it is also common for move/copy. However, for me it is very confusing and difficult to chose the correct center point for a rotation if I’m constantly been distracted by the most of the time overlapping preview of my selection. This said if the drawing is very detailed I have to zoom in extremely to be able to snap to the right entity. That wouldn’t be necessary without the preview. Additional rotate a large drawing selections will compromise the performance - CPU is going like crazy.

It would be nice to have an option to turn this preview on/off.

Would it be possible to extend the tool for importing points with a label so that when importing points into the drawing (as it is now), the attributes of the point are taken from the csv file and written to the point’s own properties? See attachment. This would extend the functionality of the tool and I assume that it would also lay the foundation for the possible re-export of such points from the drawing to a csv file, including all the details.

I have set the grid/snap value to X=.0625 Y=.0625 on all 4 viewports.
When zooming in and out the grid/snap scale changes from .0625 to 3.90625. at this point the grid/snap points differ,
This causes a variation in the grid/snap reference points lending to drawing errors.

example
When I use the grid settings defaults .01, when zooming in and out, the grid/snap scaling doesn’t seem to have this issue.
Other values do, See below.

set value first zoom second zoom next zoom

	point		point		point ...	

0.01 0.1 1.0 10.0 ...
0.02 0.04 0.4 4.0 ...
0.04 0.16 1.6 16.0 ...
0.05 0.25 2.5 25.0 ...
0.0625 0.390625 3.90625 39.0625 ...
0.0254 0.64516 6.4516 64.516 ...

Why is there a squaring of the original set value? Which then becomes a new zoomed grid/snap value?

As a heavy mechanical drawings user, it would help a lot to have an option to exit a block saving as a new name and making it a new entity from that time ahead.

Example: if a have a lot of screws, one of then is behind another peace and need the to have some lines changed to hidden style lines, in the flow of the work is great if I edit that screw in place and when exiting have the option to save as a new block, to don’t mess with other entities of the same block that I don’t want to change. Yes, there is a workaround that is duplicate and rename the block prior to the editing, but a save as seems to work easier.

Thanks Andrew and team!

Hi Andrew

In QcadCAM when using the new Themes or User Created Themes the Layer and Block Tabs Appear to be reversed in East and West Positions.
I have discussed this with forum user PeteVick and he cannot reproduce this behavior in Qcad Pro... he suggested submitting this bug report.
I didn’t notice this until he pointed it out and don’t expect it to be high on your list of things to do..

PS We are both using Linux Mint 20.1 (64bit) which is based on Ubuntu

When I modify partly a DIM with “Stretch” or changing one Extension line position with drag and drop the Value text is updated which is nice working. Unfortunately the previous value stays in place and is overwritten by the actual value. I think for a good readability the previous value should disappear in the moment when the new value is presented.

Hello dear CAM developers!

I need to use the same tool at different spindle speed in a single machining file.
I would deeply appreciate if you could add a Spindle Speed edit field in the CAM Profile Toolpath edit window in order that each Toolpath can have its own Spindle Speed value (same as you did for Feed Rate and Plunge Rate)

FYI, the tool on my concern is a laser who’s power is driven by the Spindle Speed PWM signal.
I need to be able to do both engraving and cutting in a single file.
Alas! this laser tool is defined with a fix and unique number (99).
Therefore I cannot define different laser tools with different speeds.

Many thanks
Best regards.

Case:
Drawing with text, zoom in and out with one of the common methods, text will disappear in certain zoom level

Same drawing zoomed in and out in 3.20.0.0 doesn’t show this effect - works just fine.

When saving a view, it would be great if the view also saved which block (model space, layout block, or any other block) that was active at the time the view was saved and when the view is later re-activated, the corresponding block would re-activate.

Reported is that black is saved as #00004c (dark blue)
Radek (iMac (Retina 5K, 27-inch, 2017), Catalina 10.15.7 (19H114)

My system/installation saves black as #4c000 (dark red)

When using single primary colors these get reduced to #4c, #7f, #99, #cc & #ff.
The threshold for that are #00, #65, #8b, #b2 & #e5
See: DimColorScale (png & dxf)

8 standard CAD colors fail saving correct
Black (something with #4c)
Dark Red, Dark Green, Dark Blue, Dark Cyan, Dark Magenta, Dark Yellow
(#80 turns #7f)
& Gray
(#adadad instead of #a0a0a4)

As with Gray, when mixing the 3 colors it gets rather fuzzy ...
#505050 & #555555 both turn #5b5b5b
&
#464646 turns #4c4226

Not related to OS, nor version.

The method Polyline from Segments (OC) can be configured for tolerance and simplification in the Options Toolbar.
The method Polyline from Selection (OG) has no UI or none showing.

OG retrieves a tolerance from QCAD.ini, what is initially not set:

    var tolerance = RSettings.getDoubleValue("PolylineFromSelection/Tolerance", 0.001);

The tolerance will be default = 0.001 similar as the default in AppPrefs.
The tolerance setting is included in QCAD.ini after changing the AppPrefs entry.

OG calls PolylineFromSelection.autoJoinSegments with this tolerance:

    var counter = PolylineFromSelection.autoJoinSegments(di, tolerance, this);

PolylineFromSelection.autoJoinSegments calls PolylineFromSegments.createPolylineShape
with simplification hard coded to true. (last parameter)

    // create polyline from line, arc, spline or open polyline entity:
    var polyline = PolylineFromSegments.createPolylineShape(
                    entity, doc, vTolerance, op, undefined,
                    traversed, callBacks, undefined, true);

I would like to see the simplification optional and default = true.

Arctic_Eddie reports failing CAM offset at exactly these points !!!
Reported is a faulty arc with radius of over 360,000mm.
- I can not reproduce this under QCAD working further on the Polys with NaNs.
- However the direct offset of such controlpoint Splines is erroneous.
(see file in post 30902)

Arctic_Eddie reports arc radii of over 10,000mm.
- These don’t seem to be faulty.
- I agree that BiArc fitting should be bound to a lower and certainly to an upper limit.
- That should be huge otherwise faint curvature is represented by many
wobbles or too quick by straight lines.
(All this, keeping in mind that QCAD doesn’t return the optimum fitted BiArc, see: https://www.qcad.org/rsforum/viewtopic.php?t=4859)
