New to "Forms" in F360

[crullier]

Hi guys I have to quick questions.

1 - Once a form in created (see loft). How can I go back in time to tweak the geometry I used to define it - or rather make different selections.

2- When using rails for a loft, does he line or curve need to be "single" curve? What if I have a profile composed of several line sections?

3- I take it that forms are used for sculpting and once the form is developed, you can turn it into a solid for further design and constructability?

Thanks in advance.

okay guys, I just figured out the answer to the multiple "chain" of lines. 

but I still do not know how to re-define a form.

1.  No change because it is a sculpt body, edit feature or sketches with history turned on that occurred before the sculpt body, then edit the Sculpt body with the new tweaks.

2. No.  But until you select all the rail sections the command will spit errors at you, blaze on regardless,

    For profiles in Patch - select each segment to build the profile, Click the + button when profile is complete, and start the next profile.

3. When finished in Sculpt, you will receive a solid or surface body, unless the conversion fails.

Might help...

2. It does not have to be a single ccurc]ve, but if you do use more than one segment the have to be either tangent(G1) or curvature continuous(G2).

I noticed that while I can change the sketches etc, I always need to delete the sculpted body and re-created it again. In other words I was expending that it would keep a relationship to the curves and or that there would be an edit function unless I am not seeing it.

Nope. In Fusion 360 T-Slines are not parametric and there is no remaining like between the sketches and the T-Spline.
