Hi,

The Edit SOP will lost when you select a component(don't move actually) and switch from move tool to select.
I know it is because the edit sop has no effect for result. I'm making a tool working with the Edit SOP. But it often lost by some click. How to avoid this lost?

Thanks for any tips!

Hello @jerry,

Your Edit SOP are lost probably because it has never edited.
Once you have do just one operation (translate / rotate / scale) you can switch from move tool to select and is still here.
That's normal.
