Hi Tudor,

re:
> Michael can u make last message as first one ? so It should be ~ pinned

Sorry I'm not sure how to do that. I can put a link to the first one in the wiki resources page though, would that help?

Thanks, - Michael

I'll make a new topic just for scripts, here will be questions !

ohayo
wanna ask about rotation - wanna do a to bounding box option on pressing hotkey
first testing on curves -> there's an option in v4 -> crv.planarFrame
tested - but it's shifts from bounding box -> gives planar frame but in another location
my questions ->
1. knowing 2 coordonates is it possible to make a frame ? accordigly to http://moi.maxsm.net/ it needs 3 (as it is from bbox to frame)
2. if upper is true wich will be (z) knowing x & y, next hotkey for flipping axis ()
3. if they are other scrips for rotation ?

shortly what I desire (unify rotation with some extra)
r - rotate
rr - rotate + bbox (planar frame 2d)
rrw(rrs) - rotate bbox + increase/decrease by amount (2d)
rrf - rotate from bbox + flip axis (x/y/z)
rrfw(rrfs) - rotate increase/decrease by amount (3d)
rc - rotate copy
rrc - rotate + bbox + copy
ra - array
rra - array from bbox

Hi Tudor,

Well 2 points does not identify a unique frame, the 2 points can form a z axis direction for the frame but there is nothing that locks down the x/y axis directions to a single answer. Depending on what you need it can be possible to do something like the AutoCAD arbitrary axis algorithm (link) where you take a fixed direction like the world z axis and use cross product of that and the z axis to produce an x axis.

If you want the 2 points to be an axis to rotate around, you could try the RotateAxis command or factory, that takes 2 points instead of a frame and then a rotation angle and the rotation will be around the direction vector between those 2 points.

Sorry I don't understand this one.

any plans for opensubd ?
an example https://youtu.be/gzyO8S5FLUU?t=181

Hi Tudor, yes I do plan on supporting OpenSubdiv style edge weighting imported through FBX format.

Ohayo !
wanna ask about techincal aspects hiding behind cad modeling
what's the reason to have always a solid shape ? why can't be done a bool operation of a plane and a surface knowing the plane normals ?

---

I believe it's essentially for Print 3D : you must have a thickness different than "0"
so a solid and not a simple plane surface who can't exist in the reality! ;)

And some practical for know how cost some volumes of materials for building or what is the density of something! ;)

But in Moi you can make Boolean operations with plane, surface with thickness = "0" !

---

HI Tudor,

re:
> why can't be done a bool operation of a plane and a surface knowing the plane normals ?

That's because MoI is designed to try and not behave differently depending on which direction an open surface happens to have as the "positive" normal direction.

The booleans are based on working with solids. If you are working on all surfaces you should use the Trim command instead of booleans usually.

dragging points from a curve doesn't snaps to points of the same curve

---

Hi Tudor,

> dragging points from a curve doesn't snaps to points of the same curve

Yes, that's intentional to avoid having consecutive points get stacked up on top of each other too easily, such stacking degrades some of the mathematical properties of the curve and can cause problems.

ohayo !
have a rectangle, wanna draw a small chamfer - at a good zoomout.
Q: It impossible draw without disabling snapping ? i'm asking about an option for snap distance !

---

Trim
t - trim add point
s - trim single segment ( can crash if not selected from object that was separated, idk how to fix)
added
c - join curves after deleting unwanted segments

fixed UnionJoin script
earlier opened surfaces where duplicating

Have you somewhere a repository of all your cool things ?

In general it's difficult to work on something where you're zoomed out so that it is too small on screen. It's good to zoom in in such situations so you have some room on screen to work with.

There is a setting though for how far your mouse cursor needs to be from a snap point for the snap to engage, that's under Options > Snaps > Object snap options > "Snap radius".

i might forgot, but this should work after copy/paste with coordinate frame
moi.ui.alert(moi.ui.getLastOrientationPickerFrame().origin.x)

1. construction lines + align on surface + rect center
drag construction lines & place the first point, second point I think should be autoaligned to surface

2. pointpicker.addSnapPoint( startpt, moi.ui.getText('Closed') ) I dont see text toolbox- is any trick behind

Hi Tudor, re: #2:

> 2. pointpicker.addSnapPoint( startpt, moi.ui.getText('Closed') ) I dont see text toolbox- is any trick behind

When you call moi.ui.getText( 'textid' ); that looks up text in the current language's string table for the text of the given id value.

There is no id value for "Closed" so your call there is going to return an empty string.

To fix it you could just pass some text directly instead of calling moi.ui.getText(), or use a valid textid like 'Closed snap'.
