Change view to Top/Plan

[tbexon]

HI All

 

I'm sure I'm missing something obvious, but I've been searching through the Function reference aswell as preference selectors, and I'm struggling to find what I'm looking for.

 

Basically within a PIO I need to set the view to a specific view, then for a better User Experience I want to return the user to their previous view (Code Below). This works fine if the user is in a 3d view, however if they are in Top/Plan it will always swap to 3d, which whilst not a massive disaster also isn't ideal. 

 

What i'm looking for is some kind of command where I can check whether the user is in a 3d view or 2d, and then, if in 2D, set the view BACK to 2d once the operation has been completed.

 

xAngleR, yAngelR, zAngleR, offset = vs.GetView()  # Saves current view for Later
vs.SetView("0d", "0d", "0d", "0", "0", "0")  # Sets view to top down

vs.SetView(xAngleR, yAngelR, zAngleR,offset[0], offset[1],offset[2])  # Resets View back to previous user view

 

 

Thanks in Advance!

here's what I use to find out if I'm in top plan.

 

topplan = vs.GetProjection(vs.ActLayer())

if topplan != 6:
	vs.SetView(xAngleR, yAngleR, zAngleR, offsetPt[0], offsetPt[1], offsetPt[2])
    
#0 = Orthogonal
#1 = Perspective
#2 = Cavalier Oblique 45
#3 = Cavalier Oblique 30
#4 = Cabinet Oblique 45
#5 = Cabinet Oblique 30
#6 = Plan
#7 = Section
#8 = Section Plus

And if you need to return from a 3D view to top/plan, you can also set the projection:

https://developer.vectorworks.net/index.php?title=VS:Projection

 

Alternatively, you can use vs.VSave/VRestore/VDelete() to save the current view and restore it at the end of the script.

 

You can also use SetPref(9873,TRUE) to prevent a screen redraw when the view is changed but then you MUST call SetPref(9873,FALSE) after you set the view back. You will see the largest speed increase in a 3D view from this.

 

You may also be able to avoid changing the view by setting the planar ref ID to a plan in the orientation you want. (Assuming you're changing the view to perform an extrude)

Amazing thanks!

 

Working code if it's of help for anyone:

 

projectionMode = vs.GetProjection(vs.ActLayer())
    if projectionMode != 6:
        # If the user is NOT in 2D Top/Plan View
        xAngleR, yAngelR, zAngleR, offset = vs.GetView()  # Saves current view for Later
        vs.SetView("0d", "0d", "0d", "0", "0", "0")  # Sets view to top down
        vs.SetPref(tb.PreferenceSelectors.DisableScreenRedraw, True)  # Disables screen redraws temporarily
        
# ------------- Other Code here ----------------------#

if projectionMode != 6:
  # If user is NOT in Top/Plan, then reset 3d view
  vs.SetView(xAngleR, yAngelR, zAngleR,offset[0], offset[1],offset[2])
  vs.SetPref(tb.PreferenceSelectors.DisableScreenRedraw, False)  # Enables screen redraws
