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.

When editing an existing toolpath to update the parameters of the selected tool, we can update the Feed Rate and the Plunge Rate, but I couldn’t find any way to update the Spindle Speed.

Even when using the Edit Tool KE button, we can edit parameters of the tool on concern but none of the modification is applied to the current Toolpath because as I see, tools parameters are copied fron tools definitions to a Toolpath only at creation of this Toolpath, but Toolpath are not updated accordingly.

Could you please add an edit field for Spindle Speed in the CAM Profile Toolpath window?

Many thanks’, and best regards.

Yes I’m aware that the U.S. survey foot has to be discontinuing December, 31, 22. However - as we’ve learned in the past it takes decades until a unit will disappears for good.

Andrew,

When switching from Default to Dark mode the text on alternating rows is hardly visible.
We can customize this color.

It would be easier if a proper default color is set on switching to and back.

Perhaps the user preferences can be remembered.
Perhaps only when the contrast would be affected.

Andrew,

When we use Lengthen/Shorten (LE) with a positive amount the result is clearly visible when indicating a side of an entity.
With a negative amount there is seemingly no preview.
It is generated and shown but one can not distinguish it especially with solid lines.

Adding an orthogonal auxiliary preview shape some N pixels long would do the trick.

CVH

Andrew,

Usually I point to something to start with.
Sometimes I want to point away from here but then the arrow is where I just clicked.

An option on creation would be nice.
The capability to reverse the Leader orientation afterwards is another method to get it pointing the intended way.

A Leader entity is stored similar as a polyline.
I think it would not be difficult to reverse the basic polyline and update the dimension shape accordingly.

Case description: “Hatch from Segments” (HS) detects correctly an open loop but fails then to set the circle marker for an easy visuelle identification.

Same scenario tested with “Hatch from Selection” (HA) ...
... everything works like a charm

I would like the ability to extend dimension lines beyond the extension line when using tick marks. Images are attached and posted here: https://qcad.org/rsforum/viewtopic.php?f=31&t=9785

Currently, the model space can display lineweights at scale 1:1
It’s very convenient when drawing small objects that will be printed at scale 1:1 : it makes it easy to anticipate the final aspect of the printed drawing.
But this feature is unusable for architects or users who draw large objects.

Therefore, it would be very useful to have a factor to multiply lineweight display in model space.
For example : if i know my drawing will probably be printed at scale 1:50, i set the value of the lineweight factor to 50.
Then every line would be displayed 50x thicker in model space.

Instead of having to click on the toolbar, it would be useful to have a keyboard shortcut for undoing the last fit point (or control point) while drawing splines. Preferably it would also be nice to allow the user the ability to set what the keyboard shortcut is for this function.

Andrew,

Related topic: https://www.qcad.org/rsforum/viewtopic.php?f=32&t=10094

When entering 1’ 1’‘ in an input field.
- As the size of the rectangle in the topic
- As the length property of a line selected in the drawing
- ....

Returns 13 in a drawing in mm.
And also in a drawing in inch what turns out to be correct.
But also in a drawing in foot.

Similar, entering 1’ with a drawing in kilometers it returns 12 units = 12 kilometers.

Suggestion to add spelling checker / spell checker for all text boxes

Andrew,
On behalf of user Kmeelo

Polygonal Area adds measurements text with 12 decimal digits and then as short as possible.

Current formatting path see: https://www.qcad.org/rsforum/viewtopic.php?f=32&t=10450&p=42833#p42805

Related forum feature request: https://www.qcad.org/rsforum/viewtopic.php?f=31&t=10458

I also see a misconception of the term ‘precision’.
Numbers precision is the amount of significant digits disregarding the position of the decimal point.
12 decimal digits is about the largest precision for numbers with 5 integer digits.

I’ve been able to make this work as proof of concept very easily, but many of the functions are inaccessible/difficult to override from post-processors.

Desired functionality:

1) Enable “Add Profile Toolpath” UI elements all the time (remove setRequiresSelection)
2) CAM Profile Toolpath Dialog: Drop-down menu of available Layers. First option “By Selection Only” 3) “By Selection Only” continues to pass EntityIds of selected objects (existing functionality)
4) Choosing an active Layer will use the Layer as source of EntityIds
5) Any changes to Entities on a Layer will result in those new/removed/changed objects being re-generated without having to manually select and update the tool paths. Either do not recover list of EntityIds from the ToolpathBlock, and instead use “live” each time it’s regenerated, or additional functionality to determine if a LayerId is associated with the Toolpath, and then lookup EntityIds.

I assume the persistence of the Layer selection would be available within the Toolpath, so that it will automatically update EntityIds every time a Toolpath is regenerated, without having to select Entities and updating the toolpath manually.

For large projects, being able to force select objects based upon layer dramatically reduces mistakes and speeds up the workflow.

Thanks

Andrew,

When we alter about any property of a Hatch entity it seems to be recreated with a newer/higher handle.
This doesn’t influence the drawing order in direct.
But already changing the drawing order of a Hatch it is recreated as a new entity.

It starts to matters in drawing order when there are multiple entities with the same drawing order and that after save/reload. Entities with the same drawing order then receive a new drawing order based on the original but sequentially increasing based on handle.

Because a Hatch is recreated with a newer/higher handle each time a property changes it will thus always end up above the others with the same order even when the original was created earlier.

This is more pronounced when copying/pasting entities from a source to a target drawing.
The original Hatch drawing order is retained but it will always be above existent entities with the same drawing order in the target drawing after save/reload.

Most other entities are probably just updated in situ.
It is unsure to me at this point if merely updating a Hatch is even possible.
And perhaps this is related to the addObject ForceNew flag what is false by default.

Nach einigen Überraschungen ....

Es ist möglich Layer in nicht eingefügten oder unsichtbar geschalteten Library Items unbemerkt zu löschen ....

Fallbeispiel 1:
Ich arbeite an einer Zeichnung die u.a. den Layer “Gelbe Linie” benutzt.
Ich füge ein Library Item ein was auch einen Layer “Gelbe Linie” hat.
Ich lösche - aus welchen Gründen auch immer - in der Zeichnung das Library Item weil ich es erst später wieder verwenden will.
In der Blocklist ist es natürlich immer noch verfügbar.
In der Zeichnung lösche ich den Layer “Gelbe Linie” da ich diesen nicht brauche brauche - habe aber natürlich nicht im Kopf welche Layer in meinen Blocks verwendet wurden.
Nach einiger Zeit will ich den Block (den aus der Library) wieder einfügen - dieser ist nun aber unbrauchbar da der Inhalt welcher auf dem Layer “gelbe Linie” war fehlt.
Das Library Item neu aus Library laden um das bereits existierende zu reparieren scheitert da das erste nicht überschrieben werden kann. Ich muss den ersten Block löschen um den neuen benutzen zu können.

Fallbeispiel 2:
Da das selbe (löschen der Layer) auch passieren kann bei unsichtbar geschalteten Blöcken kann es dazu führen das ich zig bereits positionierte Blöcke zerstöre und neu platzieren muss um meine Zeichnung zu reparieren.

Fallbeispiel 3:
Ich sehe in meiner Zeichnung einen Layer “Gelbe Linie”. Weiß nicht was das ist - schalte alle Layer unsichtbar außer “Gelbe Linie”. Klicke auf “Auto Zoom” um zu sehen was den auf “Gelbe Linie” ist. Finde nichts = also leer! Lösche Layer “Gelbe Linie”. Der Layer wurde aber von einem im Moment nicht verwendeten Library Block verwendet. Es gibt keinen Hinweis das ich damit ein Library Item zerstören könnte ....

Lange Rede kurzer Sinn: Wäre es machbar/sinnvoll Layer in Blöcken nur löschen zu können wenn ich mich im Edit Modus der Blöcke befinde?

If I try to flip in both directions at the same time - you can’t see this effect.

I wanted to make it so, that SVG units translate 1:1 into CAD units; I use the German localized QCAD and entered 25,4 into the box with the wrong result, i.e. the same as 25; Entering 25.4 got me what I wanted: The question box needs the point and ignores the comma.

Hi,

I am using mac version and I have annoying issue with trackpad.
I use qcad primary with my trackpad and under application preferences (Graphics View/Navigation), my setting is as follows.
Mouse wheel / two finger swipe: Scroll (Trackpad...
Enable pan gesture : unticked (found that enabling this often goes into pan mode when I am just moving my pointer around)
Limit zoom and scroll to prevent overflows : ticked (hoping that this would prevent weird zooming issue. I will describe what I am experiencing later this page)
Reverse mouse wheel direction for zoom :unticked
Mouse wheel zoom factor: 1.02

Things work as expected:

• panning with two finger swipe

• and the rest

Issue I am experiencing:

Often, when I am zooming in and out with two finger gestures, the view suddenly sets to some weird state and my drawing goes off the ruler.
The mouse point remains where it is.

Workaround:
Reset viewpoint with autozoom and navigate around.

Expected zoom behaviour:
I expect viewpoint to zoom in / out at where my mouse pointer is or at least the centre of current view point.

Andrew,
The Arc segments of Polylines with Global or any Local Width render faulty where Global Z or any of the arc’s local Z is not zero.

In the attached drawing setting the Global Z of the inner poly to 5,10,...

The setting of Z to not zero affects the radius of the projected arc and not the bulging of the poly.
It also affects the projected widths of the line inversely, but not by changing the widths properties.

Pritty rare combination! True.
Qcad is 2D native! True.

Flatten will resolve this.

It is not a purely visual rendering fault, the poly will explode as such.

Maybe similar flaw as with uneven scaling blocks with arcs.

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.

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 ...

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

Andrew,

I can’t find any documentation concerning OffsetBothSides under Misc .. Modify.
It is not listed in the QCAD features nor in the changelog.

There was a Feature Request FS#1130 for this, I think you might want to close that as being implemented.

The tool asks for a Line, Arc, Circle, Ellipse, Spline or Polyline.
It also seems to act on shapes that can be exploded to such entities like Text, Dimension and Hatch entities.

There may be many ‘Result loop not closed’ or ‘No offsets possible’ warnings when hovering over entities on a drawing.
The preview may be partially, one or two sided and even two sided partially and closed with semi-circles.

I only successfully created a dual offset for open Splines, open or logically open Polylines.
All other attempts result in a single offset at the indicated side.

There are the usual exceptions for Polylines with arc-segments but that is related to small arc segments and being tangentially connected.
Only tested it on a Win7 platform.
I don’t suspect that version 3.27.8 includes a fix for that ...

Regards,
CVH

Andrew,

Most probably not related to OS or QCAD version.

When hatching an area with Hatch from Segments (HS) there might be false positive warnings on open loops.
It seems that this is related to the orientation of the indicated segments and the order of selection.
The real problematic position is not always the first that is reported.
Loop count is increased even if it is a single loop.

Included a basic test drawing to replicate these.
Further details to replicate the issue are in the file.

CVH

Andrew,

In the included screen grab below, left is when drawn cubic, closed periodic, from 4 points.
Right is when the file is re-loaded.

It is hard to select the incorrect shape when pointing near it ... Probably it is referring to the correct internal shape.
After drawing it explodes to a Null length polyline with 2 identical vertices.

I can’t include the error in a file as it reverts on re-load.

The same issue exist for quadratic, closed periodic, from 3 points.
