Loop Length

[RobJV]

How much longer do we have to work out equations to simply get the loop length of  a sweep into our parameters?

Does 2012 have this yet?  I just want to pass the sweep length parameter to my partslist without buying addins, wrtiting code, or calculating volumes and areas etc.

Just wondering if its possible to dimension arc length of a bend in 3D sketch, hence trying to creating a parameter that can give total length of a 3D sketch route?

Hi! Arc length dimension is available in 2D Sketch but not in 3D Sketch. In 3D Sketch, if you create a bend, the linear segments on both sides are still dimensioned to their untrimmed length (before the bend).

I don't think there is a way to constrain total length of lines and arcs in 3D Sketch.

Many thanks!

Hi John!

Thanks for your response, I am actually looking to retrieve total length (derieved length) of the loop in 3D sketch by creating a parameter. So that can be exported to drawing part list.

Not trying to constrain the sketch using loop length as a function.

Possible to do this in an another way?

[johnsonshiue]

Hi! This can be done via iLogic rule or VBA code. There is an API call to measure the loop length of a given curve. Another way is to take volume of the part (assuming it is a single solid body part) and divide it by the area of the sketch (assuming all loops participate in the sweep). You will get the length.

Here is a sample iLogic rule. "AREA", "VOLUME", and "LENGTH" are all user parameters with proper unit respectively.

AREA = Measure.Area("Sketch1")
VOLUME = iProperties.Volume
LENGTH = VOLUME/AREA

Many thanks!

Bob,

Would this work for a 3D sketch? I am looking at having a curve length from a 3D sketch fall out in the parameters.

Thanks,

Hi @bryan

This solutions is for 3D sketchs. As its not possible to dimensions arc length in them. So the way around is to create volume and use the formula to calculate length. It was to automate acquiring length parameter in a 3dsketch.

Otherwise measure>loop to get the length manually in any sketch form.
