I annotate PDF floor plans which were created using CAD software. Using the Acrobat edit tools I can make lots of very useful changes to those individual CAD objects. However, there does not seem to be any way to change the color of those objects.
I have been able to change some colored lines to appear black, by converting those objects from RGB to Black and White using not the standard Edit tools, but the ones found in pre-flight or something like that. I'm sure that is not really the intended use of that function, but it is the only way I've found that works at all.
At the last company I worked for they decided to save money by forcing all us employees to use PDF X-Change instead of the Acrobat Professional that so many of us were accustomed to using. I resented the change, but having no control over the situation I did my best to adapt. There were some features that Adobe offers that were not able to be performed using PDF X-Change and remarkably the opposite was also true.
One of those features was they allowed you to easily change the color of objects while In Edit mode. So, I know it is possible to perform within the standards that PFD's use, but if the capability is available in Adobe Acrobat DC I have not been able to figure out how to use it.
I would appreciate it if someone could confirm whether or not it is possible to somehow change the color from say black to red of an object like a line produced by a CAD program.
I should mention, I do see where there is an option to edit an object using an external program from within DC. I've tried pointing that to my Autocad LT program, but that doesn't seem to work. What type of program is DC looking for when it gives you the option to edit an object using an external program?
