How to purchase FlexTools?

How is sketchup flextool subscription?

Do you mean FlexTools for SketchUp? If so, what do you mean by “How is…”? If you want information about it, look at the Extension Warehouse page I linked to. Also look at the link at the bottom of the Extenstion Warehouse page.

Fine i wants to know if it has anything like annual subscription and the likes?

Do what I told you and go to the FlexTools site. It’s explained there.

Ok thanks
