Hi Nate -- But that (finding the Length of the Bend) depends on the Neutral Axis Radius rather than the CL of the Bemd. -- Lew
Dimensioning curves by arc length?

Irrelevant to the discussion at hand - but yes - I know that and that depends on the materials. Either way makes no difference in Alibre Design if I can't dimension it.
Yes Lew, your post #16 is exactly what I am talking about and want to see. When I was working, many of my jobs involved tubes, hoses and wires. Always needed total lengths. And if I remember (its been a long time), hoses and wires were usually splines that needed length dimensions.
And Nate & Lamar I agree 100%.

Yes for solid bars, not on hollow tubes.

There is a different equation set to use with "non-rectangular" and "hollow" shapes. The basic equation is set for Rectangular Solids. -- Lew

Hello colleagues,
if you are talking about bend lines, i would imagine that they are coming out of an module like sheetmetal...
(or you can calculate them by yourself...including the length ;-) (looks like a little bit more work...)
An dimension on an arc with a known radius an an known start and end angle looks like the first step to it.
This one should be possible by Alibre programmers with not so much effort (the measuring tool is already capable of this calculation;-).

Stefan

Hi Nate -- What you need is not the centerline length but the formed Neutral Axis length. See attached. -- Lew

Yeah, we talked about it 8 posts and 15 weeks ago.
Looks right to me.

Nothing new yet, but I'm told it will be looked at.
We've been asking for it for at least 2 years!!! But it seems that too often Alibre seems to spend more time & resources on cosmetic changes (such as the look of Icons in V26 vs V25) rather than real improvements. And I still keep getting RED dimensions in drawings when I don't touch anything near that particular area.

You are very impatient. I've had things in the cue for over 6 years. But in the mean time they have been added. Yeh!
Doesn't have to be 'near' to affect the underlying index numbers - any topology change will lead to re-assignment of edge/face/vertex numbers.
V26 does have a 're-attach dimension' function, to reduce work tidying the aftermath.

A requirement for exactly this came up for me today, calculating the major axis of an ellipse that had to be laser cut in a tube to produce a round hole on the ID for a round part crossing the tube, perpendicular to the axis of the tube.
