Hello,
I created a rectangle using the 2-point rectangle function. I can edit all the corners but not the bottom left corner. Rounding and trimming don't work. What am I doing wrong?

Grafikfehler in Raspian? Bemassung ohne Ziffern

2025-10-03T12:18:43Z

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!

Cutting up an ellipse

2025-09-24T04:22:50Z

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?

Ausdrucken des Maßstabs mit der Zeichnung

2025-08-03T04:28:26Z

Hallo Community ...

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 ...

... jeder Plankopf hat ja auch 'feste' Angaben, also solche, die sich nie ändern, wie z.B. den Namen des Erstellers. Andere wie z.B. den Projektnamen muss man selbst eintragen.

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?

Spline through points - poly line

2025-04-22T09:56:53Z

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?

Text as rectangles in drawing but shows in print preview

Calculation support on dimension label

2025-01-03T15:59:52Z

Issue https://github.com/LibreCAD/LibreCAD/issues/1953

Implemented in 2.2.2-alpha

Similar to using <> for the dimension measured.

Now, it's supported to do calculations:

<> Inches
{<>*25.4} mm

<> Degrees
{100*cos(<>) mm}

The calculator muparser is used for calculation.

Given radius circle tangent to two crossing lines

2020-03-29T02:58:05Z

Hello,
I have been wondering for some time how to draw a given radius circle tangent to two crossing lines.
Here is the solution I found and I would welcome any other suggestions.
1- draw two crossing lines.
2- create a construction layer.
3- Build the same two lines on the new layer, they will be endless.
4- Still on the construction layer, draw a fillet with the required radius,
5- On the drawing layer, draw a circle with the "centre, point" tool, using the centre of the fillet and its radius.
The lines and circle will be perfectly tangent, for instance the "trim" will work on both lines.

Regards,

Christian

Line types

2024-11-20T09:14:57Z

Hi. I want to use the librecad program to pattern leather goods. I don't know how to create a curved line from points at a given distance. It would be nice to be able to customize the type of lines(dotted, dashed) for this purpose. Or how can this be done differently, anyone have any tips?

Pdf Export entweder ganz weiß oder sehr dünne blasse Linien

2024-09-03T03:57:44Z

Hallo Freunde!

Ich arbeite seit gestern mit dem neuen LibreCAD 2.2.0.2 und habe einige Schwierigkeiten, vorallem beim Export in pdf.
Entweder die Zeichnung kommt komplett weiß ausm Drucker oder die Linien sind plötzlich so dünn, dass man sie kaum sehen kann.
Auch wenn ich mit Farbe arbeite sieht man sie nicht, bzw. nur ganz blass.

Hoffe jemand kann mir da weiterhelfen?

Grüße!

Editing using the dimensions of the grid outside the object

2024-11-02T10:01:21Z

We want to create a window opening, but the edge and target destination does not coincide with the grid.

For editing, we will not type numbers or use offsets with numbers. The solution is to use the grid outside the edge to obtain the desired regular dimension between the reference and target points.

Question about specifying holes in file for CNC drilling

2024-10-26T14:40:53Z

Hi I am new to LibreCad and CNC. I am making a drawing/file of a plywood sheet with multiple holes drilled throughout. I am OK with how to show & locate the holes. But what I don't know is what does the person who runs the CNC need from the file? Just the centerpoints of all of the holes & then a note about the diameter? Or if the drawing shows all of the holes(circles), then the transfer of the file into the CNC language will include the centerpoints?

Thanks for any help that you can give me.

Dimensions vs X Y coordinates

2024-08-06T12:38:08Z

I want to use the Cartesian X-Y coordinates information in the lower left corner of the screen to draw entities on my project plan.

By using an image on a layer as a template on which to overlay a site plan drawing, I intend to generate a Letter size page for a DIY home improvement project that requires a permit.

Previously, I have had an architectural floor plan drawing scanned and rendered as a PDF. With that file opened in Libre Draw, it was scaled to an A4 page, exported as a SVG that is then imported into LibreCAD onto a similarly sized page. With the proper settings in Drawing Preferences, the measurement functions work. This process was not arrived at in a straight forward manner. Many hours of research were required off-and-on for this solution, so I cannot say I remember exactly how I got this to work. For some reason the coordinate readout corresponds to the drawing's measurements.

With my current project, I am attempting to create a drawing within a portion of an image. I have successfully set up the proper dimensions in the Drawing Preferences/Dimensions/General Scale and Length Factor windows so that the largest real world length will fit into the portion of the application form image/template. The length measurement functions on the drawing correctly indicate the real world measurements. I want to draw a line that represents a fence line that will be the the reference edge from which the other features will be placed in the drawing.

The thing that escapes me is when I want to use the X-Y readout at the bottom of the screen to create a line that will correspond to those real world dimensions, the two references do not agree. I have been unable to adjust any parameter in either the Drawing Preferences or the Print Preview/Scale that will cause this to work.

Although I have already learned the software sufficiently to generate a couple of drawings, I do not consider myself to be a proficient LiberCAD user. I rely mostly on the tools not the command line.

Can someone point me to what I have missed?

Please note: LibreCAD 2.1.2 on a Ubuntu 18.04 OS.

DWG/DXF-Import

2024-08-14T03:04:52Z

Hallo,

ein neuer User ist an Bord. (oder wäre der Post in Englisch besser?)
Nach 35-Jahren AutoCAD habe ich als Rentner keinen Zugriff mehr auf AutoCAD.
LibreCAD ist eine Alternative, da ich überall gelesen habe, dass ich auch DWG und DXF-Dateien importieren kann. Nur wie?
Ich habe mir letzte Wocche LibreCAD heruntergeladen. Dann müsste ich ja die neueste Version haben.

Viele Grüße

No vectors in PDF output

2024-07-28T03:06:40Z

Hello there Libre CAD forums!

Could anyone help with the above topic - when I draw some simple vectors in Libre CAD and use the print function (Microsoft Print to PDF) the vectors do not show up.

I know that in AutoCAD there is a coordinate system that needs to be set up in order to "centre" the printed page. There is also the "layuoutwizard" command.

Is there similar in Libre CAD?

Tim.

Nutzung auf einem Surface mit Zeichenstift

2024-07-05T00:31:43Z

Hallo Zusammen.

Ich nutze LibreCAD auf einem Surface. Alles gut soweit nur ist mir gerade aufgefallen, wenn ich den Stift zum zeichnen nutze und bemaßen möchte, will er mir immer zwangsweiße erst eine Hilfslinie zeichnen.

Sobald ich mit der Maus arbeite geht es wieder ohne.

Kennt das Problem Jemand und kann mir erklären was ich einstellen muss damit das auch ohne Hilfsline funktioniert?

Drawing line with a specified endpoint (feet and inches)

2021-03-19T11:49:33Z

I am seeking help in how to draw a line with a specified endpoint in feet and inches, but I receive an 'Expression Syntax Error' because LibreCad doesn't understand my input. I began the drawing by setting the workspace units to 'Architectural'. The line I want to draw is 23 and 5/8ths inches long (just under two feet in length) with the startpoint @ 0,0,0. Here are the steps I entered from the command line:

[Command]: line
[Specify first point]: 0,0,0
[Specify second point] ; 1'-11 5/8",0
[Message from LibreCad]: Expression Syntax Error

What is the correct syntax for expressing 23-5/8" ?

How to place the 2 docks at the right side of my display

2024-03-15T07:32:14Z

I'm trying to place 2 docks at the right-side of miy display.

But these docks changes of place if I drop the dock to the right.

What is the solution?

What are the standard snap tools.

2024-03-12T10:06:24Z

snapping is still clear to me. Which tools can work well together to create a drawing?
Is there a good example somewhere?

Printing Scale Tips...

2024-03-01T07:30:01Z

If you work with architectural or furniture drawings, I believe this is the best way to work with scale drawings.

Here are some tips:

- First of all, read the User Manual: https://docs.librecad.org/en/latest/about/index.html

- Draw everything in full scale (1:1), even your blocks.

- Learn how to use the Library Browser Dock to insert everything that is standardized.

- Use the scale factor to insert drawings or texts that require printing scale adjustment, such as sheets, title blocks, finish schedules, standart details, etc...

- Whenever you create a new block, make sure that it has been saved with the same measurement units as your default model (see Application Preferences and Drawing Preferences) or this will generate a scale incompatibility with the line weight configuration.

- Adjust the printing scale factor according to the scale defined when inserting the block.

- Watch the workflow demo

Demo.mp4

- For now, that's it...
