Start point of dimention with ActiveX

Does anyone know of a way to get start point of dimension
with ActiveX method?
How would that be done?

Thanks for help

Hi Fatty.look at from Jeff answer

 

Unfortunately only for aligned dimensions. For other
dimensions, the best choice is to use DXF methods.
If you are using VBA and have no alternative, then
you might use the entities within the dimension block.
But there is no direct ActiveX link between the
dimension block and the dimension so you need to
use copyobjects method to get access.

 

Thanks Adesu and Doug
I think I know what to do now

 

Hi Doug,

Maybe I don't understand the question and/or your reply. One or the other is likely.

I just wonder if you meant to say CopyFrom method, rather than CopyObjects?

Hi Joe,

No, I meant copyobjects.

Unfortunately, activeX access to critical dimension objects has been
limited by AutoDesk. Since Adesk doesn't seem to be arbitrary in
its practices, the implication is that they don't want third parties too
much control on their dimension objects. There may be some justification
for this approach, since dimensions have varying levels of reactor
behavior built-in.

The OP wanted access to the first extension origin of a dimenion object.
DXF access to that is relatively simple and that is what I would use if I didn't
need ObjectDBX or reactive access to the dimensions.

The dimension block is accessible from the dimension object via ActiveX 2 ways.
Copyobjects method can be used to copy the dimension to another drawing or to a
dbxdocument. By using the IDPairs argument and converting the id's back to objects, the
dimension block can be found. This has been demonstrated very effectively by Tony T.

Handle arithmetic can also be used to find the next block definition following
the dimension object. Although others have expressed contempt for this method, dismissing
it as a kludge, it seems another satisfactory alternative to me when not using ObjectDBX.

Once the dimension block object is found, I usually store its handle with
the dimension object to re-access it during reactive callbacks.

Copyfrom method only applies to dimension styles. The source of a dimension
styles variable settings can be a dimension object.

Does that help? Too much?

Doug

 

Thanks, Doug. That was an unexpected education.
