Constraining Spline Length?

[Hickoz_bro]

Hey all,

just wondering wether there's anyway of constraining the LENGTH of a spline in sketches? for example, if your modeling a hose of a specific length, is there any way of ensuring that it's length doesn't change?

Are you using Routed Systems?

[Hickoz_bro]

Inventor 11 sp3...


nothing more then that... is routed systems an add on? or an integrated feature?


will look into it now.

Cheers

Inventor Professional allows you to set a specific spline length for a hose. (Routed Systems is part of Inventor Professional)

okay, yes i am aware of that, but unfortunatly i don't have access to it... so i have to do it the hard way...

so back to the original question. is there anyway to constrain the length of a spline....

[JD Mather]

Not that I am aware of.

Have you looked at rightmouse clicking the spline then selecting bowtie, place as many as you can then constrain the spline to gain control.

thanks lazer, but i know well enough how to make the spline fully constrained, i was purely wondering whether there was a way to constrain the length of a spline curve so that i could ensure that it's length doesn't exceed certain values.

i realise that it's length will depend on it's start finish point, but i don't see why you can't constrain it's length and allow its "tension" to be the variable
