If you have a 3dsketch centerline of the tube, why not just use "Measure Loop" and let Inventor do all the hard work? Bob S.

That gives you the bent length.

Back when I used to do bend tooling full time, the engineer never really cared to account for the bend allowances since for our CNC pipe benders, we had to provide excess length for clamping and then trim the ends afterwards, so the bent length was used and additional length (4-6") was added for clamping, etc. Of course if you are working with simpler manual bending machines and want to do a few bends without having to trim the ends afterwards, I can see your point in needing to figure bend allowances too.

Nice machine. The length isn't that hard to "go figure" I guess but maybe they should change the "Measure Loop" command to the "Measure Closed Loop" command. I make a closed loop sometimes, measure it and subtract the connecting line length, but you still have to "go figure". ~Larry "Sean Dotson" wrote in message news:3ff17d36_6@statler... > see page 8 of this document > > http://www.swagelok.com/downloads/webcatalogs/MS-13-138.pdf > > -- > Sean Dotson, PE > Autodesk Inventor Certified Expert > http://www.sdotson.com > Check the Inventor FAQ for most common questions > www.sdotson.com/faq.html > ----------------------------------------------------------------------- > "Larry Caldwell" wrote in message > news:3ff17c4a$1_5@statler... > > Go figure! > > ~Larry > > > > > >

Measure Loop works for me on Open Loops (in a 3d Sketch anyway). "Larry Caldwell" wrote in message news:3ff18961$1_1@statler... > Nice machine.

We bend tube from 1/2 to 10 diameter. To get a closer estimate of the length of the straight tube we figure the length of the bends along the nuetral axis (similar to figuring the length of sheet metal bends). Take the center line radius of the bend minus 1/6 of the tube outside diameter. Figure the length of the bend(s) using this radius and add in all the straight lengths. It will never be perfect but will be close even for different material.

I think the easiest method is to close the loop on the sketch, measure the loop, then subtract the length of the connecting line, but the whine was about Measure Loop not measuring the open loop directly. ~Larry "KMOZDEN" wrote in message news:29523937.1073438495349.JavaMail.jive@jiveforum2.autodesk.com... > We bend tube from 1/2 to 10 diameter.

I have had no problems using Measure Loop on an open loop, at least in the case of 3dsketches consisting of lines and bend radii only. I have not tested it in other situations like perhaps a 2d sketch though. Bob S.

Right ... it will on 3D sketches but not 2D sketches ... hmmm. I use 3D sketches for 3D stuff and 2D sketches for the much greater volume of 2D stuff ... maybe it will at least get on the "Soon" list. ~Larry "Bob Schader" wrote in message news:3ffbfb91$1_6@statler... > I have had no problems using Measure Loop on an open loop, at least in > the case of 3dsketches consisting of lines and bend radii only.
