mesuring distance on a composite curve

[stone2008]

hi everyone,

could anyone solve my case:

I need to divide and mesure distance on composite curves, for example, a line followed by an arc followed by another line.
I use solidworks 2008.

please, help, I really can't find how to do it.

Please expand upon what you need ... with an image if possible.

Are all the lines and arcs to be the same length?

Hi,

thx for taking time.
Here are two sample of what I need to do. One of them is the middle curve of a stair.

One way would be to use the Split Entities tool to break the composite curve into seven pieces, and then use an Equal constraint on them.

Pull the roll bar up so that only the feature is suppressed.
Highlight the composite curve in the tree and hit the measure tool ....

You may be able to achieve what you desire with a composite curve and a curve driven pattern. You may have to create some geometry specifically for the pattern.

If the equality does not need to be precise, a simpler version of CorBlimeyLimey’s suggestion would be to use line segments constrained to be on the curves and have equal length, (think approximating a circle with a polygon). The make path sketch tool may help by allowing the line end points to cross between the arcs.
