I have been working on making a model plane before i build it and want to use tape as the hinge for the control surfaces but when it comes to modelling it i cant seem to find a way to make the tape flexible in a way that would allow it to act as a hinge as it would in real life. Is there a way without simulations to make a thin flat rectangualr part be flexible on say a center line of the sketch?
Flexible as it is used in SW is just the ability for you to have subassemblies that are under defined and can be moved according to sub assembly mating.
For example you could have a linear slide sub-assembly, if you brought this in as a rigid assembly the slide portion would not move. If on the other hand you made this a "flexible" sub-assembly, you could then move the slide in your top level, provided it's mates are appropriate.
For your uses, consider mating the moving parts with an edge mate and then allowing those parts to move like a hinge.
SOLIDWORKS is largely a rigid body modeler. That means the geometry you produce is assumed to be infinitely stiff and only undergoing rigid body motion if there are degrees of freedom for that. Typically, you might leave something like tape out of the design and instead mate the two pieces that the tape connects in a way where they would hinge against each other. If you do want to add tape in for cosmetics/animations you can do it through a method like you see in this video of a flexible spring (GoEngineer - SOLIDWORKS: Animating a Spring).
I would just create a coincidence mate on an edge of wing, and control surface and let it pivot on that.
You could also set mate limits so it only goes up and down a certain number of degrees.
I had a suspicion that that might be the case. i greatly appreciate the informative replies. And i think ill try to just use the cosmetic/animation approach in order to visualize the tape hinge. Thanks Again for the assistance.
