Hi , I am new to Pointwise

I encounter a problem while using it for generating unstructured mesh.

When I want to use the Create->Draw Curves->Curve on Database
The button is in shade, and I just can not use it.
However I do have an existing entity, even if I click on the entity on which I want to draw curves, it still doesn't work

Anybody knows how to do it ?

What type of db entity do you want to draw on? The line/curve on db can't be used on shell entities. If you want to draw a curve on a shell entity simply use the regular line/curve tool and create a multi-segment curve by picking points on the shell. See the attached image for an example:
