Modify the position of the dimension

[Anonymous]

hello,

I am looking for a way to move the dimensions of Figure a as shown in Figure b.

(Using revit API)

a)     

b)

You can probably achieve what you need using the dynamic model update framework DMU:

http://thebuildingcoder.typepad.com/blog/about-the-author.html#5.31

The DynamicModelUpdate SDK sample demonstrates its use:

Dynamic Model Update used to maintain relative position between elements: Move a section marker to maintain relative position with a window; When execute the AssociativeSectionUpdater Command:

• Register the SectionUpdater
• Select a view section element and a window, it will associate the two element.
• Add a trigger so that the SectionUpdater class will be invoked for any geometry change to the window
• When the geometry of a window changes
• Move the section to a new location based the window’s location point and rotate the section and make it vertical to the window’s FacingOrientation.
• The calculation is on the RejustSectionView function.

Cheers,

Jeremy

Hi!

The easiest way to achieve it may looks like this (Iron python shell code):

dimension = selection[0] # selected dimension

tx = Transaction(doc, "move dimension")
tx.Start()

ElementTransformUtils.MoveElement(doc, dimension.Id, 0.5*XYZ.BasisY)

tx.Commit()

Of course you need to determine shift direction and distance, I don't know these rules
