Hey all, another what could be just a simple question. I have to insert 45 degree angled lines quite often and the only way I know how to do it is inserting a line close to 45 degrees, adding a dimension, then clicking and dragging the one end of the line to as close to 45 as I can get. 45 degrees doesn't need to be exact in this application but is there any way to do it easier other than adding a symbol or the way I'm doing it currently?
Unfortunately I don't believe that's an option for me. I wonder if there is something in my config that needs to be changed? I tried selecting one line and then both as well to try this option.
Try using the RMB before or during drawing the line:
(note: often a quick right-click does not work to bring up the RMB menu, try holding the mouse button longer)
What version of Creo are you using? I can't find the menu that you are showing in your screenshot.
Also, have you considered doing this kind of "drafting" in part mode? It is so much easier to use the sketcher instead of
the archaic drafting tools available in the detailed drawing mode.
Also, sketches are fully parametric.
And also there is an option to automatically create 45 degree lines:
If you use cosmetic sketches, then your sketch can contain variety of linetypes.
I was answering Paul's question on how to get the menu you show in your picture. Based on the picture he shows it appears he is using Creo 3 or 4. I'm also not sure that moving to Creo 3 or 4 would solve the issue you are asking about. I think all he's showing is the menu you would get by selecting RMB after you enter the line command the line you create is still going to be measured from the horizontal and not from the line you want to reference, unless something has changed. The menu similar to the one Paul shows looks like the following in Creo 2. The angle specified using this menu is also an on-demand setting meaning it's applied once and not remembered by the system.
I found that and set it, that will work well when the line I'm mating to is horizontal, but do you know if there's any way to make that snapping reference default the line it's attached to? Basically if the line I'm working with isn't horizontal can I get that 45 degrees to snap from the mating line? Upon playing with it more, it looks like it'll snap a free standing line at 45 degrees but not a line that's using another line as a reference starting point. 
Sounds like an Idea that should be submitted 
Life is way too short for sketching on drawings in Creo IMHO.
I am on Creo 3.0 now but I believe it was the same back in Creo 2.0 that when you go into the Sketch Tab in a drawing, there should be a "sketcher preferences" choice under the "Settings" section. And after you choose that, a dialog pops up and one of the options is angle with a degree option. If you turn that on and set it to 45 as you start sketching lines, it will then be able to snap to 45 degrees in all 4 quadrant directions. And I also believe you can change that degree for other lines if you want to start sketching them at a different angle later on. Hope this all makes sense and I will attach a pic of the selections.
Hi Shane, thanks for the reply. That does make sense and someone brought it up earlier. The problem is that the lines in these drawings are usually not just horizontal or vertical. Even when selecting the angled line for a snapping reference the 45 degrees still only applies as if it was a horizontal or vertical line. I know if I adjusted the angle degrees to be 45 degrees from the angle of the line it would work great, but that would probably end up being the same number of clicks as I'm already doing with the original method. If I could just upgrade to Creo 3 or 4 that would solve this!! Thanks for the reply though.
