How do I change a component in an existing design?

[DrPR]

I have an existing design created in V11.0 Multisim/Ultiboard. I want to change a single component to replace a transistor in a D2PAK to a part in a DPAK.

I edited the component in my users library to use the DPAK footprint.

I transferred (Transfer to Ultiboard 11.0) the revised design to Ultiboard. All components and traces were ripped off the board and the board outline was deleted. All that is left is a board outline rectangle with lots of components scattered around it.

This happens if I transfer from Multisim to Ultiboard, or if I open the ewnet file from Ultiboard.

The documentation/help says nothing about modifying existing designs.

How do I make changes to existing boards without having to start over from scratch?

Don't transfer to Ultiboard - this basically creates a new design - what you want to do is forward annotate only (which will only update the design).

Optionally you can transfer the UB Netlist only and reimport from Ultiboard.

Thanks.

Forward annotation seems to have done the trick.
