Subtitles of the Movie

I will now open the A2 drawing file and perform a substitution of the existing XREF and complete the solution to my simulated problem. Remember that I had externally referenced the floor plan to the A2 sheet, I am going to switch to model space with dynamic input back on, I can go ahead and type XR and you can see what I am doing on the screen instead of having to look down at the command line. I will now enter, this opens the external references tool palette and you can see the file name is A2 and I am referencing the X-plan in model space and X-border in paper space. I am going to focus on X-plan and I am going to substitute, this is how I am going to do it. First I am going to change the reference name, now I am going to click down where it reads found at, I am going to click in the path and then I am going to click in this small icon with the three dots and instead of looking for X-plan I will now click on X-reflect, I am going to open that and you can see the immediate change. I can also look at the file references pane and notice that I have successfully substituted X-reflect and you will notice that X-plan is a nested XREF of X-reflect. I know I am using several X's which may make this sound confusing but again I am using that designation to make a note of all the drawing files that are being referenced through out the project. Now I am going to close this tool palette and I will once again begin to turn layers off that I do not see at this time. So I am going to click on that icon and I believe I have selected all the layers that need to be turned off. So now I tap the escape and I am going to switch back to layout 1. This is how I want the drawing to look for now and I will make changes later. Before I complete this portion of the tutorial, I'd like to mention the vis retain system variable. I am going to close this drawing file, save the changes and I going to open that same drawing file again. Notice how it is remembering the layers that need to be off, that is because the vis retain system variable is currently turned on. Let me show you what this means, I am going to type vis retain and I am going to enter and it indicates that it is currently set to one which means that vis retain is on. It is visually retaining the layer properties the way I left them based on the previous session. I am now going to set this to zero and I am going to enter, once again I will close the file, save the changes and open the file and now I come back to the file and because vis retain is off it did not remember the changes that I had made to the XREF layers. So I will have to type vis retain one more time, turn it back on, go back to model space and turn off the layers. This is how I want the drawing to look, I will now zoom extents, switch back to layout 1 and close the drawing file. I will open it one more time and because vis retain is turned on the layer states are remembered. So keep that in mind when you are working with XREF's, that is a very important system variable to be aware of.
