problem loft

[apo]

Bye to all,
I'm trying to do some tests with the loft, but I can't use the profiles as guidelines.
I mean, if I make circles on different planes and make lofts between them, then I can't add a line that gives the shape of the profile, to the solid.
would you tell me a good tutorial to understand the most basic operations?

thanks and soon
apo

already that there are also a couple of doubts, really basic, to ask you!
The first thing I want to ask you is if there is a way to draw closed figures with the line.
i.e. if I design a line with multiple points these are detached between them by default. Otherwise, for example, from the rectangle, where if I go to move a point on a corner, I also move the two sides.
I hope I explained. .

and then if there is the possibility to remove all the constraints with only one button. . .


Thank you so much!

1) When performing the loft, the guidelines must intersect other geometries, in your case the circumferences
2) you can go on the official guide http://wikihelp.autodesk.com/inventor/ita/2014/help/1283-inventor12833) to close the lines you must use the constraints, in your case the "co incident"

hi bradipo, thank you very much for the answers
1) Unfortunately I failed with the loft, I think I do not use it properly:
to try your suggestion I created 2 circles on two different planes, parallel between them and translated on the y axis
after that I created a line on a vertical plane that touches the two circumferences, and should be driving for the loft
At this point I make the loft and choose the two circumferences as sections, and the solid appears, then select the line as guide and the solid disappears leaving only the 2 full circumferences. .
I also tried to move the line into the circumferences, but it doesn't work... and even if the line joins the two circus centers (I found that the loft works from a circumference to a point! )

2) I understood the coincidence bond, and it seems to me that the best way to connect two lines between them, like two sides designed with the rectangle instrument, is to draw the two lines far away and then make the points coincide.
is there a method to give the bond of coincidence to two lines that are already coincident? (in the sense that they were designed coincident with the line tool.
would be much faster and more precise than drawing lines, moving them to make the bond more easy on the two points and re-setting the coinciding point in the right place... I hope to be clear)

3) then I try to request if by chance there was a function to remove all constraints to a drawing with only one button


Thank you so much!!

When you create the sketch of the guideline, do you project the geometry of the circumferences?? I think that's the problem. the line does not intersect circumferences. .
ps: sorry but point 2 I did not understand

ciao or,

x deactivate the constraints in the sketch mode I attach you an image... However, this does not serve to eliminate already created constraints but to disable constraints before drawing your profile. . .
If you want you can create your geometry with automatic constraints, and if you need to create a line that you don't want "self-containing", just hold down ctrl and create the line...

I think there is no x way to eliminate all created constraints.. In any case, wait for the answer from the most experienced

hi and good day:biggrin::biggrin:
