Dividing Lines and splines into equal parts

[Anonymous]

Hello, I need to divide lines and spines into equal parts, like you can see in this AutoCad Video:

How can I do this in Fusion 360?

Thank you

I believe per our discussion this is what your after....

Nice video... thanks.  What if my line isn't an exact "8 inches"?  Can I set the distance based on the second point?

For straight lines and splines, measure it first, then enter that number as the Extent.

For arcs, measure the angle first.

For ellipses, you need to define what you mean first

Hi Mr. Mendonca,

If you have some F360 API proficiency look at: 

<CurveEvaluator3D Object getStrokes>

It is not difficult to write the appropriate function. For TF360 members with the access to F360 core guts, it would be a breeze!

You can use a dimension as a reference in the pattern. Before starting the pattern feature hover the mouse pointer over the dimension you want to use and note it's parameter, in the screencast below it's d1. The screencast is for an arc but the same procedure works for a line. Note, you don't need to add a point to the start of the line\arc you can use it's endpoint.

Thanks Mark,

I think this would meet my needs if I could reference driven dimension as discussed here:

https://forums.autodesk.com/t5/fusion-360-ideastation/ability-to-reference-driven-dimensions/idi-p/5...

(I can't tell if this is still in development or not.)

What I have is an edge whose length is driven by other constraints.  Then I want to subdivide that.  Each time I change the other constraints, I need to edit my timeline and do a measure/copy/paste.  It would be great to add the driven dimension, give it a variable name, and then set that variable name as you suggest.

Referencing driven dimension is still not implemented I'm afraid. Your only workaround is if you can calculate the length from the dimensions you have, see this thread\post for an example. You might need to use a different workflow, do you have an example design you can share? Export as an f3d and attach if you have an example.

Gotcha, thanks.  I think I can rework my design to allow me to compute the dimensions myself.  For now, I don't change things around that much, so if I have to manually update the pattern length, I can live with that.  (If I get stuck, I'll post the specific problem for guidance!)

Hm. This looks easy in your video but I cannot select the dimension to split my line like that.

[etfrench]

You don't select the dimension. You hover over it to get its ID (name).  Once you have the ID, use that in a formula.

You can also get the ID in the Change Parameters dialogue.

[tcurdt]

I just had the eye opening moment about the id part somewhere else - but that still doesn't quite get me all the way.
Here I have d25 being 30mm:

but when I enter it it goes well beyond that:


Also not sure what the "Suppress" does.

You'll need to attach your file to the thread: File|Export|Archive file *.f3d

Thank you, Phil. For the spline, I replaced the point with a sphere (Outside of the sketch) then used the "Pattern on a path" for body. After the pattern, I created a new sketch and projected both the spline and the spheres.

Thank you so much!
