Add Budget Proposal Digital Signature with airSlate SignNow

Digital signature multi sectional resume

civil3d allows us to add digital signatures to drawings to eliminate unauthorized changes to files all I have to do is type digital sign and in the dialogue box I can attach the signature after saving the drawing I can select the digital signature from my computer I can also assign a timestamp and add a comment in this case I'm saying do not use the file unless it has an intact digital signature once I click OK I will come up and save the drawing the signature is now attached to verify that we can close the drawing and then I'm going to come up and click the open command first of all we can see that it's a signed drawing by the change in the icon let me open the drawing when I do we get the digital signature contents dialog box this shows us that the file has a digital signature and it's intact we can also see information about who signed the document and we can see the comment and timestamp another way you know that files are signed is through this little stamp icon in the lower right corner of the interface you can also use this to validate the signature if you click that it'll bring up the validation dialog box if you attempt to make a change to the file for instance I'll move the scale bar and I'll try and save the drawing it will tell me this drawing has a digital signature and if I save it it will invalidate the signature essentially it removes it you can see the icon is now gone in the status bar let me close the drawing I'm not going to save changes I've saved it once already let's try and reopen it and you can see the icon has changed meaning this drawing no longer has a digital signature
