Help net surface.

[Uzzmak]

Doing an online course i have completed the geometry but cannot chain said geometry properly in order to net the surface, if possible i could send educational blueprint also my drawing. the errors read as follows

"across curves are out of sequence" 

"partial chain: path between first and last entity not found"

Assuming the drawing is correct, you'll usually get this error if you're selecting too many/too few/the wrong entities. My guess is you're told to change the selection method to window and then drag it around the wireframe? If so, make sure the window is just large enough to select all of the entities you're required to but small enough that you're not including entities that you're not supposed to.
