Re: hatch on scale

2025-12-01T12:36:59Z

since you mentioned a scale of 1:100, it might help to play with the scale setting in the hatch dialog.

The hatch pattern is first scaled before being used to fill the hatching area. If the scaled pattern is much larger than the contoeur, there's not much left to be shown within in the contour after trimming. If the scaled pattern is too small for the contour, the pattern is duplicated to fill the contour, and if the number of duplicates is considered too large (100x100), hatching would be skipped.

I'm wondering whether it helps to show the hatch as solid fill in this case.

Re: How to select a layer from the command line

2025-11-23T08:06:08Z

With exeperience in AutoCAD it's easy to ask for (even) more when solutions or new developments are released. There's unreasonableness in this so I am a bit indecent I guess.

As far as I saw this does not come with the possibilities to set properties of the layer (plottable, color, thickness, etc.).

BTW, thanks for replying.

Re: How to select a layer from the command line

2025-11-23T07:41:09Z

Hope my lines do not look too critical. In fact I am exploring the boundaries.

I read the replies https://forum.librecad.org/Introduction-tp5728328p5728337.html but do know what exactly to answer. It feels like I have to be half a developer to be able to use LibreCAD.

Some things might be easier than I think. I saw files (somewhere) where lines like the following fit in. Guess I can figure this out.

// set layer
{
{{"setlayer", QObject::tr("setlayer", "set active layer")}},
{{"sl", QObject::tr("sl", "set active layer")}},
RS2::ActionLayerSet
},

But doesn't that require a C++ compiler? Although this is not completely alien to me, I do not intend to go that far to be able to use LibreCAD. I am a user in the first place, not a coder. I like VBA, GoogleScript, AutoLISP, Clojure (just toying with that). As you can see from this, I do not make applications. (I do not compile with an exception for Clojure.)

But (as written above) maybe it's easier than I expect.

Re: How to select a layer from the command line

2025-11-22T13:20:35Z

this is possible, yet in 2.2.2-alpha branch (not in production yet).

I've added a couple of commands exactly for that:

Commands for layers creation and activation
Two simple commands were added to let management of layers via script file (this addresses #2092)

cslayer - activates layer with specified name
cnlayer - creates and activates layer with given name

More information about is might be found there - https://github.com/LibreCAD/LibreCAD/pull/2114

Development snapshot for 2.2.2-alpha is located there - https://github.com/LibreCAD/LibreCAD/releases/tag/2.2.2_alpha-latest

Re: How to select a layer from the command line

2025-11-22T12:45:07Z

eengebruiker, I don't know what you thought about https://forum.librecad.org/Introduction-tp5728328p5728337.html which is a call to make user interface, including commands, more user accessible.

Maybe you could add the command to the LibreCAD code, eg https://github.com/LibreCAD/LibreCAD/commit/64aa33a24de97adfa5424b1fd6bcbd12138e007b

say:
// set layer
{
{{"setlayer", QObject::tr("setlayer", "set active layer")}},
{{"sl", QObject::tr("sl", "set active layer")}},
RS2::ActionLayerSet
},

Would require commands and ActionLayerSet to be available.

Hmm, it's more complicated than this. In the Layer widget when you click on the layer it sets the layer in the list, so the layer in the list must be identified.

There might (possibly) be some clues in this fork/branch: https://github.com/emanuel4you/LibreCAD/tree/developer

May you share the the DXF with such issue?

P.S
1) btw - what do you mean by "edit corner"? Move the point or apply commands to 2 lines that are near to the corner?
2) Are you sure that these lines near the corner are lines, not a polyline?

Hallo in die Runde!

Ich bin ganz neu beim CAD-zeichnen an und für sich. meine wahl viel auf LibreCad. was mir sehr gefällt. ich übe mit YT-anleitungen.

beim ersten bemassen ist jetzt ein unerwarteter fehler aufgetreten: es erscheinen keine ziffern/zahlen. in der druckvorschau erscheinen sie dann zwar schon, aber nicht in der eingestellten farbe.

habe mal die KI gefragt. diese meinte, es könne auch mit den systemeinstellungen (grafik, Raspian) zu tun haben. habe alles versucht mit neuinstallation, überprüfung der grafikeintellungen des systems und die einstellungen unter LibreCAD.

kommt jemandem so etwas bekannt vor? ich würde ansonsten gerne mit LibreCAD weiter machen. nur die bemassungen sind halt dann schon wichtig...

danke schon mal vorweg!

Re: Cutting up an ellipse

2025-09-30T01:41:45Z

Hi dxli ...

I was then able to solve it with a trick solution:

Where the ellipse of the stand intersects the table tube, I drew a line through both intersection points and used this line as a “knife” for trimming.

The lines of the table leg did not work as a “knife”, as it was not the part between the lines that was trimmed away, but half the ellipse.

But thanks for your help.

Re: Cutting up an ellipse

2025-09-24T08:25:46Z

Could you upload a minimum dxf with the issue?

Both trim/divide should work for ellipse+line.

Hello ...

I am currently despairing over a step that I absolutely cannot manage:

I am drawing - in an isometric illustration - as part of a room view a round table with a round base plate, connected by a center column.

Both ellipses are finished, as is the center column. However, the stand would cover a rear part of the ellipse. That's why I'm trying to cut out the small piece of the ellipse of the base plate that is covered by the stand (see picture).

Translated with DeepL.com (free version)

It doesn't work.

I have tried with “Trim”, with “Divide” ... nothing works.

How can I implement this?

Re: only empty boxes/frames are shown for image/text? no line thickness?

2025-08-13T06:28:07Z

I'm having a similar problem.
Version: 2.2.0-undef
Compiler: GNU GCC 13.2.0
Compiled on: Apr 8 2024
Qt Version: 5.15.13
Boost Version: 1.83.0
System: Linux Mint 22.1

I open librecad and load my drawing.
I add a dimension line. The measurement appears.
I pan the image- all measurements change to empty boxes.
Save the image, exit, reopen librecad and open the drawing- the measurements are there.
I can select a window or zoom out or in, and the measurements are still there. If I pan the image, it's all empty boxes.

Re: Ausdrucken des Maßstabs mit der Zeichnung

2025-08-04T00:30:14Z

Hallo dxli ...

I don't know if you can call it that, maybe that's exactly what it is.

When you view a drawing in the print preview, the scale that LibreCAD uses for printing is displayed at the top (see screenshot).

LibreCAD saves this scale internally in the program.

I would like this saved scale to be automatically transferred to the plan header (or to the drawing).

Of course, I can also close the print view, switch back to the drawing and enter it there as text.

That works, but I find it uncomfortable.

Re: Ausdrucken des Maßstabs mit der Zeichnung

2025-08-03T16:39:16Z

If I understand correctly, the question is about storing scaling for blocks.

Blocks are in model space, and printing is in paper space. Could you elaborate a little on how the desired feature should work?

Ich fuchs mich gerade in LibreCAD ein und habe auch schon die erste Zeichnung fertig.

Hier im Forum wurde ich auch fündig, wie man einen Planrahmen mit einem Plankopf erstellt ... das klappt insoweit auch recht gut :)

Aber ...

Wie aber ist es mit dem Maßstab?

LibreCAD passt ja die Zeichnung auf das Blattformat an ... ändert also den Maßstab von 1:1 auf 1:x.

Ist es möglich, diese Maßstabsangabe als Variable in den Plankopf einzubinden, ohne sich diese in der Druckansicht zu merken, die Druckansicht zu schließen und dann in der Zeichnung händisch einzutragen?

Re: Spline through points - poly line

2025-04-23T00:15:59Z

You can also try 2.2.2 alpha branch, the command is Spline -> Explode Spline To Lines

It works both with Spline and Spline Points and converts splines to polylines.

It is available there: https://github.com/LibreCAD/LibreCAD/releases/tag/2.2.2_alpha-latest

Re: Spline through points - poly line

2025-04-22T14:14:39Z

"Spline through points" is likely a misnomer.

It's actually a quadratic bezer through given points. It's not cubic spline, or nurbs.

The quadratic bezer allows implementing more features, like tangent, hatching.

Exploding the quadratic bezer is not currently supported. If you have any suggestions on exploding a quadratic bezer, it helps.

Britten wrote

I feel so stupid asking this especially when I have 6 plus years working with a software, but I am attempting to convert a spline that was created through points into a polyline. I have attempted exploding it multiple times and it does not work. It does with a normal spline, but spline through points it does not. So is this an oversight on the development, is there something wrong, or am I overlooking something?

Re: Text as rectangles in drawing but shows in print preview

2025-04-09T13:00:20Z

It's likely due to zooming.

The current mechanism is to avoid rendering text in tiny scales.

Could you zoom in to see the text?

If needed, please upload a sample dxf with the issue.

Re: only empty boxes/frames are shown for image/text? no line thickness?

2025-03-06T13:30:54Z

Please note, when the rendered text is determined to be too small (consider the extreme, if the whole text is only 1 pixel in height), only a bounding box is drawn, i.e. the behavior of Draft mode.
