Using Run Process in a script you can execute PCB commands.

I created a Delphi script which was running properly in both 2D and 3D modes with older versions of DXP (before AD18). After DXP migrated to 64bit the script would only run when the PCB was in the 2D view. I needed to add line of code to my script to switch from the 3D view to 2D.

Recently I learned to use RunProcess to execute PCB Commands in my scripts.

Example: To switch the PCB from 3D view to 2D view.

RunProcess ('PCB:Swithto2D')  / /  Delphi Script Code

RunProcess "PCB:Swithto2D"  ' VbScript Code

There are times when you need to short or join different nets together at a designated common point in a design such as AGND and DGND. 

In Altium this can be accomplished using NetTies if you have control of the schematic.

If you don't have control of the schematic you will not be able to include a NetTie symbol and NetTie footprint in the design.

If you don't own the schematic another option is to create a short circuit in the design and waive the DRC violation.

For example you could join two different nets using overlapping fills or solid regions.

That's it !

Here is an Altium article titled "Best Practice of Flex Circuit Design"

https://www.altium.com/rigid-flex-circuits-resources/best-practice-flex-circuit-design

It's a bit dated, it was published when AD16 was released, however it is still relevant and has some of the best graphics I have seen related to flex designs.

More flex resources:

Flexible Circuit Technologies is a highly regarded Flex resource.

Wurth Elektronik's also has some good stuff to share about designing with Flex-Rigid.

As shown above I prefer to display the Mechanical Layer numbers in my component layer pairs. This involves creating, then editing the pair and selecting N/A for the Layer Type.
