Problems with Copyright

Problems with Copyright

(OP)
Is there a way to send a drawing in dwg format where the reciever is unable to make changes to the file. I am having problems with copyright and need to be able to send drawings without the reciever having the ability to change the drawing in any way.

RE: Problems with Copyright

MalcolmNiki,

that is a problem. You can not lock *.dwg files with ACAD. You need a 3rd party tool.
Cadlock: http://www.cadlock.com/
DWGlock: http://www.brothersoft.com/dwglock-93011.html

Maybe there are workarounds like lisps in the www.
Some people contaminate the *.dwg with an Educational Stamp. But you can delete it, if you are clever...

Alternative: Think about PDF and DWF files.

Thanks Exxit,I am trying dwglock and cadlock and Our department keep the original DWG and send our clients the copies generated from the dwglock program.

RE: Problems with Copyright

you can XEDIT your drawing if the drawing is Xreferenced by the receiver.  If the reciever still manage to change the drawing, this drawing will no longer be an xreferenced

RE: Problems with Copyright

NB,
pdf's printed from a CAD programme are not secure as they can be "reversed" to a CAD file format.

RE: Problems with Copyright

Off course any thing can be reversed , but a trick is to do a
MINSERT 1 row 1 column , it can not be exploded

  

RE: Problems with Copyright

fixo,

They fixed that problem.  At least in 2007 you can explode minserted blocks.

While there is no way to stop them, you can make it very difficult for a novice cad user.

I like to lock all of the layers and the invert the layer filter to hide all of the layers.  That usually takes them a while to find.

Also sometimes just using paper space/model space will confuse them enough.

The best way though is still to print the file, then scan it slightly twisted on your scanner to pdf.
