Full Version: looking for a script to create multiple offset lines

Show messages:  0-19  20-26

I would likt ot know if there is a script to create a set of offset lines with fixed distance between them... for example 2mm between them.

thanking you in advance

Not that I know of, so I wrote the attached one for you.

Why not use the native Transform Array Dir
Pick the base point and then pick the Offset Point...
You can see or enter any dimension in the "d box"

Hi Pilou, array and offset generate different geometry. They are only equivalent for some special cases like a line.

Here's an example:

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?

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....
