Update all Viewports on a Layer

Recommended Posts

I have found the Update All Viewports command dangerous as it updated everything in the file and can take a very loooooooong time (in one case 17+ hours.) You can certainly select all the viewports and click the Update button, but if you accidentally select anything other than viewports, you don't get the button in the OIP.

This script will select and update each viewport on a sheet layer.


Procedure UpdateSheetLayerVPs;

{Selects, Updates and Deselects each viewport on a sheet layer}

{Revised to handle both sheet layer and section viewports}

UpdateVP requires a handle to a viewport. You are trying to pass it a class.

You need to change the Selct Obj line.

SelectObj(((ST=REGVIEWPORT) or (ST=SECTVIEWPORT) and (c='Elev.VP)));
