sweep a 2d profile according to two trajectories

[RitaCarmen]

Hello guys I've started using autocad recently so I have little experience. I have a problem: I can't use the sweep command using as trajectories more than a polyline yet I'm sure you can do it because if I don't remember bad I saw it do by someone.
Can you help me? Maybe I'm lost in a glass of water or I remember badly!
Thank you.

from the menu "edit" :
> polyline
you are asked to select the existing polyline that in this case you want to convert to spline
appear in the command line various options, type s corresponding to spline
and the game is made

What's the matter with you? asked how to use more than one sweeping beads and you turn a polyline into a spline?? What's up? ?

I can't use the sweep command using trajectories more than a polyline

do not use sweep, use loft with guide option

no you did not understand I want to sweep a profile 2d second not only one trajectory but two. This does not succeed me because as soon as I go to select the first polylinea that should act as a first trajectory, autocad already sweeps me without giving me the possibility to select together with the first polylinea that in my intentions should act as a second trajectory.

all I need to create a type step with custom profile of a stone helical scale.

But to make the loft I should still have two 2d profiles right?

Maybe by attaching a screenshot you can understand me better

I tried to create the other 2d profile to make the loft but I can't even this time :s. tells me that the type of cross section selected is invalid yet I created two regions. I just can't figure out what's wrong! I hope you can help me.

p.s. Sorry to bother you!

try to post the profiles in question with the sections. that we take a look at him; if I don't remember badly the sweeppare sections must be perpendicular to the guides.

always as images?

but excuse which lines you use as profile guides?

If this was the hoped result, do it with the loft command, as tristan suggested some post back!

Since you created the second profile, did you try to make a simple loft only from cross-sections? I think I understand that trajectories are straight lines, so what do you need? ?
