I have Acad V14 and I know enough to do just basic drawings. I used to know more during my working years but have forgotten a lot since I retire.

I would like to make some signs with my CNC router as a hobby but don’t know how to draw the body of the sign if I want it to have a mixture of straight border and curves. I have no problem making the text.

So I want to make the outline of the sign which will include straight lines and curves about 1/2" thick and it will stick up from the face of the sign lets say 1/2". Do I use a polyline, Trace, Spline or what? And how about the place where I will write the letters; how do I incorporate that along with the border.

When I will finish a sign, I will export the drawing to a dxf file and then the CNC software will take over

I would appreciate any guidance

Thank you John

Never thought about it but you are right, the CNC software prefers polylines. I used to make my shapes with the Line command and the CNC could not read the dxf and then switched to PL and all went fine. I haven’t tried to cut any text yet so I don’t know the results with text.

Much appreciate your time

I guess release 14 must be an obsolete version for you guys LOL, I know its old but it does the trick for me nicely and it’s free, a gift when I retired from my company.

No I don’t have Express Tools, I just have the menus and mainly I work by typing the commands at the command line.

I have made about 10 samples of a simple sign in an effort to see what I can do. They all turn nicely as a drawing in Acad but I have some issues when I try to open the dxf with the CNC.

The sample sign is a 4”x 8” rectangle. I make 3 layers (Base, Border, Letters).

The base is just a simple rectangle made with the Line command and converted to PL afterwards. This base has no thickness (don’t know if this is ok or not)

The border is made with the Line command too. Then I fillet the corners, add a donut at the top, trim the donut to suite and then convert all to PL. Then I use a 1/2" Offset to make a thick like border and then convert all to PL.

I discovered that if I use the Region & Extrude commands to make the border a solid, the CNC only sees a single line. If I just give a height to each border line (Modify Command, Thickness) then the CNC sees the border properly and that is fine.

I also try to explode the text with the Explode command but the Command says “I was not able to be exploded” So I have an issue with the letters on how to give them a “Height”

Sorry for the lengthy reply John, just try to let you know what I have done so you can see my steps and see if I do it right or not.

Thank you
