Example: I'm using the HMC3587 amplifier.
1. I created a new schematic with a S2P block to read the s-params.
2. I created a new symbol based on the schematic.
3. I created a new layout and drew the footprint + pins.
If I create a new schematic and drop the symbol down, then try to generate a layout from the schematic, the auto-generated layout changes my footprint (see attached).
How do I stop this?
