Problem Gluing Shape with Connection Points

[RhesusMinus]

Hello again.

See attached drawing. NB1-63H has connection point on each side. As has XF9.
The XF9 glues perfectly to NB1-63H, both sides. The NB1-63H however doesn't glue to anything!?
And I really don't understand why.. again.

Any logic in this?

Hmmmm.  Don't see any attachment.

Sorry... A little too stressed. Here it is...

I just did a quick test myself (Now that I've got some sleep), and deleted all subshapes named "CenikaLayoutPartNumberX". Now, it glued the connection points.

Seriously.. is the Visio graphics engine so bad that it cant handle this? Some of these symbols, with this "complexity" was used in Autodesk Actrix (that died a silent death back in 2000) with no hick-ups what so ever...

Connection points are known to be, uh, tempermental.   

Glad you got some rest and found a work-around.

The original attachment glued just fine for me (in Visio 2010). When connection points are close together, you need to click+drag near the point that you want to glue. Since the card is long and thin, Visio might be unsure about which side you want to glue.

You are right to reduce the complexity of your groups, though. In the article When 2D Glue Breaks, there is a quote from the Visio development team regarding 2D glue, connection points, and shape complexity:

There is a threshold of 25 shapes (including sub-shapes) for showing a bitmap image of your selection while dragging. Above this threshold Visio only shows a rectangular outline. Using 2D glue is dependent on the bitmap drag image being available, so there is in effect a limit on the complexity of shapes that want to support 2D glue.

There is a registry key to remove the 25 shape threshold. Set: "HKCUSoftwareMicrosoftOffice12.0VisioApplicationDragBitmap" to "REG_SZ". The side effect is that you will encounter degraded performance as you drag more complex shapes around.
