Missing Make Point Driving bottom on the Option Bar

[Anonymous]

In revit help has been said we can change a reference point to a driving point by clicking on Make Point Driving bottom. But when I select a reference point, there is no Make Point Driving on the Option Bar. What can I do? What's wrong with that??

Did you Host a Ref. Point to a Model Line?

The help documentation is misleading. You cannot add driving points to a line unless that line has first been created as "3D snap-able" and therefore already has some driving points.

Thank you for your help. It had been a big problem for me. Thank you a lot.
