First angle vs third angle projection
First angle vs third angle projection
(OP)
Our company is beginning to work with a customer who's drawings use first angle projection. For our shop and suppliers we will supply drawings with third angle projection. I'd like to make it easy for myself and others here to create and verify their drawings using first angle projected views, then switch to third angle for release to our shop and suppliers. I expect after verification and switching to third angle there will be some drawing realignment needed.
This first thing I noticed is that when switching projection types named views do not update, only projected views. This makes sense so I can set this up and instruct the others to only use projected views.
I am wondering if any of you know of a property I can add to the sheet that will update the first angle and third angle symbol display (I still need to create the symbol files.) Or if any of you have a macro that would update the symbol?
I have cross posted this on SolidWorks forums. I appreciate your help. Thanks, Diego

Just make a template for 1st angle drawings and a 3rd angle drawing. I am assuming you know how to set a drawing as 1st angle and 3rd angle under properties.

RE: First angle vs third angle projection
It occurs to me now that the simpler approach is to just set up 1st and 3rd angle templates, then switch them back and forth when needed to verify the layouts. But when I try this it doesn't seem to update to projection type, even after reloading.

RE: First angle vs third angle projection
A lot of SW seemed to work perfectly, IF you did things in a linear manner, as if you knew where you were going and what route you were going to take, when you started, but SW fought back in strange ways if you wanted to back up partway and take a different path.
It was often easier, and faster, to just restart from scratch.
I think you have a valid complaint, in that real world design is not always a nice linear process, and these days (and 20+ years ago too), it would have been beneficial to select the drawing projection well after starting the model, and indeed to be able to generate two complete sets of drawings with different projections from the same model, for different markets.
Since SW is Euro-centric, or even Franco-centric, requests like that may be met with blank stares by the time they filter back to France, because chances are that the programmers working for Dassault have little or no experience with the 'Merican way of doing things, and chances also are that they look down on such practices as stupid and backwards and just too ancient and wrong to care about.
