"Upload a new font style to AutoCAD"?
1st of all, two terms are needed to clarify.
Do you mean "text style" when you wrote "font style"?
There is no "upload" function for a text style or font style in AutoCAD.
So with my understanding, you probably ask
If the former, you have to find a font somewhere and install it in your pc.
If it is a "TTF" windows font, install it to windows font folder.
If it is a "shx" font, you have to paste it to this folder
C:\Program Files\Autodesk\AutoCAD 20XX\Fonts
If the latter, type style in command line then the "text Style" dialog pops up.
Click "Help" button then follow the instruction you will be fine.
Or if you saw a text style which you want to use on other drawing, simply copy a text with the text style from that drawing then paste it to your current drawing.
HTH
Minor clarification: SHX fonts may be located in any folder, including ones on a network. The folder does have to be in the support file search path, however.
You are right. ![]()
Actually I have some SHX fonts in my document folder under SFSP.
But I think @Anonymous is new to AutoCAD. I give him/her a simple guide to start.
