hi i have made blade profile by entering coordinates in gturbo and i want to ask that after describing required vertex on blade profile .the error is that the blade tip is not connected and how the profile edge continuity is achieved in blade. thanks in advance

Hi, where the command in its turbo file profile edge connectivity can be found out?

Probably the vortex or lines are not connected.

Try this. Geometry: vortex-->connect vortices--> all --> apply.

Check in the command window whether some vortices are connected.

Do the same with lines.
