tutorial

[pmark]

Good evening, everyone!
I am trying to follow a tutorial ( https://www.youtube.com/watch?v=sdh_wjpwxoq ) to create a bulb.
use sw 2012.
Could you explain to me how to get the first 2 lines - a curve and a straight - that support the filament?
the first is using the spline since it is curved?
Thank you in advance!

do so with the propeller/spiral commandhttp://help.solidworks.com/2012/italian/solidworks/sldworks/c_helix_and_spiral.htm

I managed to make the two supports for the filament,
I created the 2 holes for the filament but can't make the spiral start from the inside of the holes? ! ?
Unfortunately this part nn is explained in the tutorial...I download an image and I ask for help I start drawing a circle inside the first hole and from there I start to build the spiral... .
But then to make a sweep on the spiral I should draw another circle but I can't create it on the origin of the spiral or at least coincident to the inner circle because it shows me no point from which to start? ! !Where am I wrong? Thank you!

I would practically need the explanation of the last part of the tutorial when creating the 2 parts of "mode" of the filament....

you have to create a plan on the origin of the spline: select the final point of the spline at the same time and the spline then click the cpmando piano and it is created automatically.
on that floor later you can draw the circle that will serve as a section for the sweep along the spiral.

As an alternative to the building of the plan you should have created your symmetric model placed on the main planes and make the spiral by setting "earth beginning" so that the spiral starts right on one of the three main planes that you will use to draw the circle coincident with the origin of the spiral.
