Hi, I am rekindling old CAD skills and LibreCAD has been awesome. I do architectural applications and I recently ran into a problem I can't find during a search on this forum. I do my drawings in separate .dxf files and draw 1 to 1. I insert those files on a ARCH D page that is 24"x36" landscape. Back in AutoCAD I would use an XREF (external reference) to plot the drawings on the page at usually 1/4 scale (1/4"= 1') I am in the US. I have not found a way to apply an XREF in LibreCAD. I can insert the drawing as a block and then scale it to 1/48 (the ratio to get 1/4 scale). This works fine except the dimensions change from a room being say 10 feet by 20 feet to the dimension changing to the real life on the page dimension of say 1 inch by 2 inches. For Architectural applications what has everyone been doing to work around this problem?
There is no XREF equivalent in LibreCAD. You have to make a frame 48 times the size of ARCH D (24"x36"). You may save this as a library file. Into this you draw or copy the architectural drawing, drawn 1 to 1. Or copy/import the frame into the drawing... how ever you see it.
Then at the printing process, in Print Preview mode, you set the scale 1/48. And print staying in that mode. Same applies to export to pdf.
I know, it's an old thread, but I'm new to LibreCAd and having fun. Here goes...
I draw everything at actual size, i.e. 1:1.
Afterwards I determine what scale is needed for the Title Block of the drawing. Usually, one has an idea of what the scale of the block will need to be, if not I draw a rectangle of approximate size to determine it.
Then I insert my ANSI spec title block and scale it as required. Now I know what my scale factor is so I can adjust dimension settings and text sizes to conform with ANSI standards for the title block size, and the I plot the drawing per my final scale i.e. 1:4, typically, on an HP roll size pen plotter.
Unfortunately, with LibreCAD, inserting and scaling is a two-step process, or I have yet to discover it along with many other nuances. Please, someone correct me if I'm wrong. As I said, "I'm new".
Insert and scaling works well for me as I have old AutoCAD libraries of hardware such as nuts and bolts drawn with a dimension of one inch on a primary dimension. So if I need a 1/4 inch hex nut, I insert the block and scale to .25. My block is "nested" and contains a side view also so when initially exploded, I get a separate block of the top view and the side view which can then be moved separately and exploded further if needed to trim views or adjust views.
