Setting attributes of current viewport

294 Views, 2 Replies

I'm trying to simply edit the default viewport in a layout that I've created. I can't seem to find any threads that were successful or answered about this. I need to set the scale, size and linetype of the viewport. When I've tried, the viewport has simply not changed. I'm afraid im not getting the current viewport. Im using ed.activeviewportid hoping that its associated with the current layout as specified by layoutmanager???

Help appreciated as always!

Dim myLM As LayoutManagermyLM = LayoutManager.Current

Dim sheet1 As Layout = myLM.CreateLayout("Sheet1").GetObject(OpenMode.ForWrite)

Dim vport As Viewport = trans.GetObject(sheet1.GetViewports(1), OpenMode.ForWrite)
This works for getting the viewport where sheet1 is the name of my layout. I was then able to access the viewport methods.
I am confused about a problem with my viewport scale. When I set the scale to half inch:

vport.StandardScale = StandardScaleType.Scale1To2inchAnd1ft

it removes the annotation found within my viewport. If I then manually click the scale after the drawing is loaded, the annotation appears. Seems buggy but perhaps I need to refresh something to get the annotation to automatically reappear.

thanks for sharing that, it did help a lot.

 

using the transaction to get the viewport(1) has made all the difference, probably because there's two showing up from the parent layout's .getviewports.count method, which complicates matters when trying to retrieve the one viewport via the layout's blocktablerecord.
