# How to measure distance along curve

Hello all!

I need a to measure a distance along a curve in the assembly environment. In example:I have  a chain link on a chain path. If i want to know the distance how long the chain link moves along the chain path you cannot measure this along a the path - only the direct respectively the minimum distance.

Finally i need a measure variable of the distance along the curve... so i it would be good to have this function inside the new 3D measure command.

Is there a workaround for this?

If the chain link curve is created in sections of the length of the chain you can do this.
However I think you have created a complete arc, then it is not possible without a work-around.

Create a new sketch on a same plane, project the curve and the chain shafts to the sketch. Cut the curve according what you want to measure. Now it is possible to measure the curve length.

Good Idea. But if i split the curve into sections i still cannot measure the curve lenght with the 3d measure command.

The only thing that works is to display the curve length with the inquire element command, or am i wrong?

Not even with PMI?

Yes, of cause! You are right!

With the PMI Smart Dimension it is possible to get the arc lenght and a variable :-)

Only the sectioning is still a problem - currently it is only possible in the part environment...

## Re: How to measure distance along curve

It should also work in the Assembly environment.

Inside a assembly sketch you  can include a chain path. And of cause you can trim this curve. But you can not include lines and arcs (the chain path) to ONE curve. This is needed to trim this one curve to one chain section....

or am i wrong again? ;-)

## Re: How to measure distance along curve

Could you upload the assembly and parts of the chain?
I don't want to draw the entire chain assembly just to test it.

It is possible. Or I don't understand your question.
