Ah yes... :)

So maybe CMorph is a little more appropriated ?

here start and target are not same size, but we can take same size...

Hi Pilou,

re:

It could be somewhat closer in some cases but still different from what offset does.

Here's another example of offset:

Ok Offset makes deformations!

---

How do you set the number of offsets and their distance apart, etc?

Martin.

For the moment i believe you must edit the file! and change values 2 & 4 ;)
2 var num_offsets = 4;
3 var offset_distance = 2;

Or use the Elephant Node Editor! But it's an another story! :)

But I have refound this! Maybe Michael don't remember of that! ;) 2012 ;)

New French Version done! ;)

Seems curves can be 3D but some fail to calculate!
Here a simple Helix

Oops, I did forget that one, thanks Pilou!

Hi Michael,
There is a limitation written into this command. Can you see if it can be removed?

OffSetMultiStep

https://moi3d.com/forum/index.php?webtag=MOI&msg=4898.19

(Inches) With a distance of 1 anything over 12 steps starts to do a skip, space miscalc

If the distance is .25, then the steps have to be 48 or more

Anyway, let me know if this doesn't happen for you....

Hi Burr,

re:

Hmm, I'm not seeing it over here:



Can you please post an example file?

Hi Michael,
Saw your post and created a new file and curve and it seemed to produce a proper result.

Changed the perameters like distance and a large count and then it stopped updating the count. If i put 50 it only created 11

closed and logged off and reopened moi and did it again and got the space...

Can you try a few different params with a larger count and verify it is only me?

Thank you..

here is running it twice with 24 count




The first time it created the 1 block with only 7 objects. the last one spaced. Selected the spaced last object and got 3 sets of 7, spaced

I am starting to think it is my test curves particular shape and not being able to offset that many times due to its back and forth wiggle...

Did some testing with a trimmed circle and offset to the outside and it would do 50 count fine

did a retest with a dramatically wavy curve and the count went down to only 2 objects created no matter how many was chosen.

I think it may be a "You cant offset that curve that many times without folding back on itself" issue...

---

Hi Burr, does it generate the missing ones if you turn off the "Trim" checkbox?



It looks like offset is having difficulty detecting the self-intersecting spot on this particular shape. If this happens you can turn off Trim and then get some pieces to work with.

That was it! And I didn't manage to use my dedouchary skills to equate the "trim" to getting the "compute anyway" result...

Just what I needed. Thanks for the help. Sorry to bother....

Speaking off offset command variations, one thing I would be very interested in: interactive Offset Through Point with the option to put in a fixed increment/step size. For example an input value of 10 would snap the offset distance to 10, 20, 30 and so on. It's something I need very frequently, but right now I still need to put in the fixed distance myself for each one. I guess it would be nice if there was a Repeat option with that as well, so you could do multiple offsets interactively (with or without the step size provided).

There is a repeat option which is active for Offset:

Hi Fabien, here is an attempt at an offset with snap increment option.

Does it normal that is always 2 offsets in the same time ?
