Composite curved: division into equal parts

[graziano-g]

hi, I need to divide in equal parts a set of lines composed of two straights and a semicircumference (in acad polylinea )
in acad there is a great tool: divide. this function divides into n equal parts a segment, an arc, a circumference or an open curve consisting of various entities previously united between them.
we pass to sw
the set of entities (described in the first row ) within the sketch although being among themselves bound (common points, coincidences ) are however individual entities then entering - division entity - and setting equality this acts on the only selected entity. if I apply the instrument -- segment -- this only acts on the straight parts.
I generated a composite -- curve -- getting a single entity obtaining a unique geometry but on this it is not possible to apply any instrument that can divide it into n equal parts....
Does anyone have any ideas?
Hello, thank you.

Have you tried with a spline?

 

[graziano-g]

with that working but my curve must have a precise geometry, how can I do with the spline to build a u? type two parallel vertical lines of equal length connected by a semicircle and to it tangent? with acad is a boys' game, with sw... probably just that I miss the procedure... .

You have to clam it as much as possible.
use the sketch with lines and strings as a reference where you put control points, create another sketch with the spline that ties to the points and then divide

I figured. However, having to be a precise geometry, line/axis of drilling is certainly not a valid alternative. patience.

alternatively divide polyline into autocad and amounts

 

[graziano-g]

already thought about this, I use currently both, where does not arrive one there is the other....
Only problem is that I lose the parametric. . .

 

[graziano-g]

wrong approach, acad in my head still does it as a master... .
the composite curve can or should be used as a path/curve in the repeat function guided by the curve.
the solid is a flange on the middle of which I have to perform a series of equidistant holes.
design the halfway line then on another sketch with convert entities the project then I make the bidirectional offset, convert into construction the central line and close the two tops. Setrudo.
return to the sketch that generated the composite curve then I notice the top of the distance that will have the hole from the top of the flange. I sketch on the flange face a hole with the center coinciding with the top of the composite curve then I perform a repetition along the curve setting the number of repetitions. variants on the subject to study: tables and bookcases.
attached the file.
Hi.

Thanks for sharing the solution

great! Meanwhile I was trying the spline optimized

... but the segment tool is not associative! changing the u spline updates but the points do not...
