Hi, I am using LibreCAD SCM Revision 2.0.9 and I have been unsuccessful at setting the scale for a drawing. I imported a .png image of a PDF scale drawing with a paper scale of 1 inch = 50 feet with a paper size of 34 inch width by 22 inch height. I see the useful reference for Common Drawing Scales at https://librecad.readthedocs.io/en/latest/appx/scales.html, but I don't see an option to set any of those scales in the LibreCAD version that I am currently using.
How can I set the scale of 1 inch = 50 feet? I have the units set as inch for both the Application and for the current drawing. Thank you. Irucka |
You have to get the scale to number. As i*m born and raised in a country with uses only metric system, can't calculate it for you, but I guess you could find online calculator inches to feet from the net.

1 inch = 50 feet makes 1:600. Just type this into the scale box in Print Preview and confirm with Enter.
Or is your question how to properly import a .png image from a pdf or a scan of a real paper plan? |

I have a PDF of a scale drawing (at 1 inch = 50 feet) that I exported as a PNG using The GIMP. I imported the PNG image into LibreCAD so that I could create a 10 foot buffer around some objects on the scale drawing. I then wanted to calculate the buffer area.
Thus, I was trying to set the engineering scale at 1 inch = 50 feet & also set the dimensions of the page in LibreCAD. Thank you. ________________________________________ From: dellus [via LibreCAD] [[hidden email]] Sent: Tuesday, May 12, 2020 5:05 PM To: Embry, Irucka Subject: Re: Set Engineering Scale of 1 inch = 50 feet Caution!

Not quite clear if the problem is solved now. If not:
You have to know with what dpi value the png is exported from GIMP. 300 is a good choice. When then importing into LibreCAD set that at the Tool Options bar. ![]() Best insert it at the lower left corner of the frame. Then scale it up 600x (from your 1 inch = 50 feet) with Scale. Up to V 2.1.3 there is a bug that it will seem to be disappeared afterwards, AutoZoom brings it back. For further advice ask again if needed. |
