Hello,
UE has a nifty distance measure tool (middle mouse drag in viewport ). I want to add the functionality of converting it’s units from CM to meters.
Which part of the engine source do I look into to try and modify this behavior.

Cheers,

I picked up a nugget from an old thread reporting a bug.
Thanks to @vellocet for mentioning the term FDragTool_Measure .

time to hack on the engine code and see what comes off it.

Cheers,

Building the engine from source and then changing the FDragTool cpp worked for me.
I now have a different standalone editor than the one that ships with the Epic launcher.

I wish there was a way to change the FDragTool cpp inside an ordinary c++ project opened by the packaged launcher editor. That way i wouldn’t have to maintain a separate editor.

Cheers
