Zoom to view in drawing:

Mike.Wohletz — Fri, 26 Mar 2010 01:41:40 GMT

I have a program that either cycles through all the base views of a drawing or works with a selected view and pushes properties that I need in the drawing file back to the part or assembly file, currently I am showing what view is being edited by selecting it so that it shows up with this:

{code}

oDoc.SelectSet.Select(oView)

{code}

This gives the user an idea of what is going on at that time and if they need to include or exclude any information. My question is how can I zoom to that view rather than selecting it since it can be hard to see the little dotted selection line of a view.

Try the following macro. Select a drawing view before running it.

Sanjay-

Sub ZoomToDrawingView()

Dim oDoc As DrawingDocument
Set oDoc = ThisApplication.ActiveDocument

Dim oDrawingView As DrawingView
Set oDrawingView = oDoc.SelectSet.Item(1)

Dim oTG As TransientGeometry
Set oTG = ThisApplication.TransientGeometry

Dim oView As View
Set oView = ThisApplication.ActiveView

Dim oCamera As Camera
Set oCamera = oView.Camera

Dim oEyePt As Point
Set oEyePt = oTG.CreatePoint(oDrawingView.Center.X,
oDrawingView.Center.Y, oCamera.Eye.Z)
oCamera.Eye = oEyePt

Dim oTargetPt As Point
Set oTargetPt = oTG.CreatePoint(oDrawingView.Center.X,
oDrawingView.Center.Y, oCamera.Target.Z)
oCamera.Target = oTargetPt

Call oCamera.SetExtents(oDrawingView.Width * 2, oDrawingView.Height * 2)

oCamera.Apply

End Sub

I just had an interesting thought. What if you could SetExtents based the view and all annotations (or other geometry if applicable) associated to the view. In other words, calculate a tight box around everything associated to that view. Starting with the view as the parent, can I loop through all its child objects (I'm assuming 2d geometry of the model) and then any associated annotations. I would need to somehow be able to calculate a rangebox (may have to be a Collection of Box2d) of where each object exists in sheet space. iterate through all those rangebox to figure a min X, max X min Y & max Y (i.e. a rangebox containing all geometry associated to the view).

Yes, that would be useful. and would be possible to do in the way that you
outlined (most drawing objects now support a RangeBox property). There are
still a few annotations that the API doesn't support (welding symbols,
etc.) - but not too many.

Can you get me started? Looking at the View object, I can't see a Property that leads me to the 2D geometry on the View. Also, how do I obtain object associated to views like balloons, dimensions, etc (i.e. parent child relationship)?

A view in a drawing is represented by a DrawingView object. However,
annotations (such as notes, balloons, etc.) are on the Sheet object. You'd
have to iterate over the annotations on a sheet and filter out the ones that
are associated with a drawing view. The process to get the associated view
is, unfortunately, different for each annotation. For a balloon,
Balloon.ParentView provides that information. But for other annotations,
you'll need to drill down to the geometry they attach to and hence get to
the associated view.

Ok but I need a little more detail. I can't see how to drill down. Can you give me one short example (pseudo code)? I'm looking at the members of the GeneralDimension for instance and I can't tell which member contains the data I need. Even if I did know, whats the data's name that gets me the associated view?

All I need is a nudge in the right direction. I've been poking around the API and can't see the realtionship bewteen and Annotation and its View.

Sorry I haven't been following this thread, but from what you say here, I
would suspect if you stepped up the Parent structure of the annotation you
would eventually get to the view. ie.... oannotation.parent.parent.....etc.

Consider the case of a linear general dimension.This is represented by the
LinearGeneralDimension object (which derives from GeneralDimension). The
following will return the first drawing curve (DrawingCurve object) that the
dimension is attached to: LinearGeneralDimension.IntentOne.Geometry.
Finally, DrawingCurve.Parent returns the drawing view that contains this
curve.

You'll need to similarly special case each annotation.

Thanks Sanjay & Kent.

Thanks Sanjay,

i was stuck at this stage while attempting drawingview.camera.saveasbimap. It was giving "not implemented" error; your solution has given a workaround.

The given solution works for me as well! Thanks!
