Amail Posted March 15, 2013 Share Posted March 15, 2013 I'm trying to make a watermark visible when the "Approved" attribute in the titleblock is blank and invisible when the attribute has a value. I want the logic to be: =(If (isblank (attrib)),"In Process","") I can't seem to make this work. Alternatively, I could have the watermark on a layer whose visibility is controlled by the presence or absence of a value in that attribute. Any ideas?

Tharwat Posted March 15, 2013 Share Posted March 15, 2013 Welcome to CadTutor . From Help Document . Check the DXF 70 of the attribute definition . 70 Attribute flags: 1 = Attribute is invisible (does not appear) 2 = This is a constant attribute 4 = Verification is required on input of this attribute 8 = Attribute is preset (no prompt during insertion) Quote Link to comment Share on other sites More sharing options...
Amail Posted March 15, 2013 Author Share Posted March 15, 2013 Welcome to CadTutor . From Help Document . Check the DXF 70 of the attribute definition . No, that's not it. My problem isn't the visibility of the attribute. I want the visibility of a field in the drawing to be controlled by the contents of the attribute. Basically, I want there to be a big "In Process" watermark permanently across the drawing UNLESS somebody has entered their initials in the "Approved" box. I want this automated, not something that a user has to control via plot stamp or the like. Quote Link to comment Share on other sites More sharing options...
BIGAL Posted March 15, 2013 Share Posted March 15, 2013 We have a "Issued for construction" lisp that updates all layout tabs so this method could change the "in progress " pretty easy, it uses a auto change an attribute value in a block. More than happy to post link if this would be usefull. Quote Link to comment Share on other sites More sharing options...
