Adaptive cable with FIXED length?

[Anonymous]

I am attempting to model an accessory for a Mitutoyo Indicator. It is a "Spindle Lifting Cable", part number 540774. First off, I do not have the Pro version of IV and will not be getting it either. Second, I have looked at the tutorials regarding adaptive 3d sketches and hoses, but the one shortcoming seems to be finding a way to contrain the total length of the cable to a fixed value, while still maintaining the ability to adjust the cable run. These cables only come in one fixed length and I would like to be able to position our cable holders to make sure they are not too far from the indicators. TIA, Bob S.

Use driven dimensions on your radii to recalculate the length of you straight runs. Just a theory. I've never actually done it. Matt

Dimension Curve Length was on my wish list. We run into this alot where flat stock must follow a curved path but hold its length due to available lengths. -- Dave Hoder Product Design Engineer idX Seattle www.idxcorporation.com

.....and having the ability to dim curve length in an IDW and NOT in a IPT sketch just makes me crazy. I'm sure this lack of continuity between the drawing/modelling modules is just a sick twisted joke of some disallusioned developer.

Here's a thought, for the path of the cable, create a construction line with a fixed center point and a set linear dimension. Have the ends of the line constrained to the ends of your path, so as one end of your path moves down, the construction line acts like a lever and causes the other end to move up. Of course this requires the path of the cable to be on a 2d sketch, and for the radius that runs over the pulley to be fixed, along with the center of that radius to be dimensioned. I'll try to get around to doing something that illustrates this later today.

I don't think having the cable constrainted to a 2d sketch would be acceptable, it needs to flow in 3 dimensions. I might just end up having to tweak the end positions and keep checking the length until it falls within a certain tolerance zone. Bob S.

Bob I've made an avi using almost the method i described. The difference is the Construction line does not have a set length.
