Is there a way to use Dynamo to Set The Scale of a Viewport in Paperspace and also set the Centerpoint of that viewport in relation to model space?
I see in the Civil 3D Toolkit package that there are nodes to view a multitude of information about viewports (Scaled, Locked, Viewport.PointFromPaperToModelSpace). However I don’t see nodes in that package or others for setting this criteria. It would be nice to be able to set your viewport scale and center it over the point in model space that you want, then lock the viewport.
Hi
Looking at this it may help you
Looks like arkance has some cool nodes for getting viewport data and I think there is one for at least setting locked. But I think you may need to dive into API to edit the properties.

There is no node to create a viewport yet, it is on the wishlist.

Can something like this be done with python, or is it best to wait until some nodes are released? I don’t know C, so that won’t be an option for me, and I am just intermediate level using python with dynamo. Set the viewport centerpoint in modelspace, and set the scale of that viewport.
Thanks
You can do it with Python and in this case the AutoCAD API
Sounds pretty cool. Are you able to get me started with something on this? I am familiar with the C3D Developer’s guide. Not sure about the AutoCAD API Reference Manual?
The way that I would prefer this type of program work for my application would be:
- Create a viewport in paperspace Layout1 tab. This could be done by user inputting the boundary for the viewport, or it could be done by user inputting a length, width, and center point for the viewport. I don’t have a strong preference either way.
- Get a point in model space that represents the center of what you want to zoom to in paperspace.
- Set Viewport View Center to the point in model space
- Set the Viewport scale based on user input.
- Lock the Viewport
The piece of this that I am not sure where to input is the case where your view frame is rotated slightly. You would need to set either the viewport twist angle or possibly the viewport view direction (by feeding a vector). Any thoughts on how best to handle a scenario like that?
I am not strong enough at coding to try and put something like this together, but would be happy to help or provide input however I can. I have attached a sample DWG with a couple of “Views&CenterPoints” in model space and a viewport in Paperspace. It is set up to be 40 scale.

This is pretty awesome stuff! I only have a couple of additional comments/questions.
- I have not been able to get the angle of the Viewport (if it is twisted) to adjust using the code you provided. I have tried three different locations for placing the vport.TwistAngle command and removed the # so it runs for each try (See image below) but haven’t been able to get that to twist the view.
- What would change in the code if you just wanted to update only the parameters of the Viewport in Layout 1. What you have set up to copy Layout1 as many times as needed is good. I am just wondering that the code would look like if you wanted to change the View Center, View Height, View Width, View Twist for the viewport already present in Layout1.
This is a great little program! Thank you for all of your time and effort!
I do not know how to use all features
But you must try it after this line
vport.Locked = False
try like this
vport.Locked = False
vport.ViewHeight =10
vport.Width = 10
vport.TwistAngle = 2.301
You should ask what you want for this topic
here
https://forums.autodesk.com/t5/net/bd-p/152
find the answer
Like this
Moving it to the location that you mentioned still does not return a viewport that is twisted. I still get 0° for the viewport twist.
Try
vport.UpgradeOpen()
vport.TwistAngle = 2.301
Using vport.UpgradeOpen() did not rotate the viewport either.
I am really sorry
I don’t know why it’s not working
Can someone help you with it? to thank
