Scale

Hi,

I want to choose a scale for my drawing in order to print it. There isn't viewport like in autocad?
How to do? I chose A4 and when I chose print preview, my drawing take the place of the whole page. Not with a scale.

Thanks

In Print Preview you set the scale and move the sheet beneath the drawing.

Maybe worth studying the manual https://librecad.readthedocs.io/en/latest/index.html

hello together i want to scale my drawing with factor 20 but sz command does not work anymore how can I reload text commands an can I write my own maybe also alias commands ? please answer and also mail me

This does not address the original question.  Construction prints include a title block and border, and then the drawing is printed inside it, usually at a scale of 1/4" on paper = 1 foot in real size.
In Autocad, there are two views available:  model space and paper space.
you draw your building in full scale in the Model space, and in Paper space you draw your title block and border.
Within the Paperspace, you open a viewport inside the drawn border, and link that to your Model space.  This is where you set the scale  of 1/4" = 1".  Now your building in Model space is "Viewed" in the paper space and when you select print, the Paper space gets printed, with the 24x36 title block/border and the Viewed model space embedded inside it.

As I understand it, this does not exist in Librecad.  So how do you scale part of your drawing to fit into the title block?  If I draw a 20' x 20' garage, with Dimension labels, do I then scale that down, and add the title block after that?  Or do I need to draw everything while doing the conversion/scaling on the model space?

Draw the building in real size. You have to upscale your title block, insert it into the drawing, then in Print Preview scale the whole thing down again.
