I am new to CNC, Mach3 and LCAM. With lots of help from this forum I have things going. I am cutting signs to learn how everthing works. I laid out a sign in Coreldraw X4. exported it in a DFX file ( autocad 14 format, Corel skips autocad 12 for some reason). Loaded it into Lcam. The wording in the sign is " Robert Cowert" but in L-Cam both "e" are missing the "-" so it looks closer to " Robcrt Cowcrt". They are not "C" the tails are almost touching so they are "e" without the horizontal bars. What am I doing wrong? If you open the DFX file with Corel, everthing is fine. Is this a bug in L-Cam or am i doing somthing wrong. I am attching both the DFX and Lcam files. Maybe one of you old hands can enlighten me.
Thanks in advance.

Hi, Mike
Your corel dxf export is dropping some lines, When I loaded it in BobCad it missed some more lines.
Replaced the text with BobCad ver. 22 text below.
Hope this Helps, Chip

Chip:
Thanks again for your help. At least I know it's not Lazy cam. What I don't understand ( not that I know much) is how it can drop that part of the "e" when I export the file but when I open the file with corel its there. Is there some other program I can view DFX files with ? Have you ever seen a program drop lines like this ?
Thanks

Hi, Mike
I loaded it into 3 different Cad's, All had issues.
Try to export in different dxf file types from your corel program.
Check the wed for free dxf viewer's or cad programs
Thanks, Chip

Chip:
I downloaded a viewer, and I clearly see the dang compleate "e" with it. If i reopen the dfx file with corel it's there also.
If I place just one really big e in the dfx file,the only program that I have that wont see the complete "e" is Lazy Cam ! I dont understand how that can be. It's crazy. I wonder if the font has some type of code that cam programs dont like.
Thanks for the input

Try exploding the DXF file 4 or 5 times. Then load into Lazy Cam.

Mr.MIKE
what corel does to a drawing in the way it handles it i have no idea. but you are not the first one to run into this with corel. they are saving the file to a version of dxf that is not = to autocad ver 12.
I downloaded you dxf and opened it in l-cam 3.00.2 to see what you were talking about-. did nothing to it,and closed it back up. then i opened it up in cambam the free beta ver, and all the eeeeeee's
were there. somehow it can read the corel dxf. then i used the export function and saved as a differant file using cambam as a filter. opened it back up in l-cam and now everything is there. attached is
the filtered file.

by the way mike i forgot to mention look at the file size differance between your original and the one i sent you.and all i did was open and export.
corel is doing something extra .

I see what you mean. Big difference in size. And the"e"'s are there. I will find cambam and try it. Would anyone know what limitations Lcam has? I have 3.00.2 and I have a license for mach3. The one thing I noticed different in the one that Chip fixed for me to try, is that the Lcam one i did never had an entity # over 49
Ben:
I transformed it 500% and it made no diffrence. I guess transforming is the same as exploding the drawing.
thanks for your time and help.

Hi, Mike
You need a LC lic. for Offsetting, Pocketing and Turn Features, Don't remember any other limitations.
