Hi Alex,

While someone who uses BobCad may come along and help out here, I would think you'd get a more informative answer at the BobCad forums?

In most Cad programs there's "usually" a way to set your origin so maybe check the help files that come with BobCad on that subject and you may find your answer.

Good luck  :)
Dave

Hi Alex,

Possibly ask this question on their forum? I would think someone there knows how to help?

Hmm....,
 If the drawing is done such that X and Y are at 0 for the origin, then if you have " As Drawn" checked
it will bring the drawing in at that origin. ( see 6.2.3 in manual ). What i do not know is how BoBCAD exports the
drawing and if you need to do something before you export it.

Rich, this why I'm advising him to go straight to the BobCad forums as they would surely venture a better guess than I ever could  :D

Well that's just sad  :'(

Do a search on the Yahoo forums for the BobCad group and there's also a BobCad forum on the CNC Zone you can try posting your question to as well.

Good luck-
Dave

If it helps, when i ask a similar question to BobCad, this is the answer I received:
The translate w/ a scale doesn't work on bobART surfaces, but if you go back to the BobART tree and edit the stock first and set that to the new size, then edit the emboss item in the tree to the same size, you can right click on Emboss Model and choose "Regenerate", which should rebuild it to the new size.

Hi, Alex

Been a little tied up hear, I haven't used the posting code much in bobcad 23, I think it's just leaving off the return for X in the Post.

Look at this G code and post an example of your G code & dxf.
