Hi Eddi,

I use for this purpose Orient Command inside MoI. I learned it from forum some time ago, but I cannot find this thread. On picture below you can find two windows. I've modelled frame (solid) and then glass (surface only), then I've copied this model and rotated by 180°. So now the windows surface is "flipped". In MoI both surfaces looks same, but if you select them and use Transform/Orient command you can see difference in axis orientation. When you use this model in some rendering software for example, you can see same difference as well.

This is very useful trick especial for mesh emitters in renderings sw.

Hope this helps.

Ciao
Mik

You can make the same with Press TAB then write Flip (you can also make a shortcut with this hiden function Flip! )

Maybe more tricky when you have several objects with many orientations, forms etc...! ;)

And it's only the surface(s) who is flipped... can be useful in certain cases!

Hi Mik,

Thanks for comment.

I know the thread
The second method described was with command >SHELL<, that's wrong, I meant >OFFSET<



But all too much clicking in a big scene.

Hi Michael,

In MoI4 beta, Feb 2018:
There appears to be a bug when changing the color Style of one or two curves that are to be blended again.

1. Draw two red curves that are to be blended.
2. Select the two curves, and blend them. The blend is red.
3. Delete the blend.
4. Change the color style of the two curves to blue.
5. Select the two curves and blend them. The blend is red.
For these two curves, blend is stuck on style red.
Replace the first curve with another curve, of a 3rd color style, next to the first curve. Blend is "stuck" on style red.

Also, the blend is stuck on the first two ends blended. A second Blend does not work between different selected ends. The first blend keeps reccurring.
(Maybe one of the reasons I commented about selecting "close to ends" of curve, with Blend the other day.)

I came across this while testing clothoid created between two end points of curve(s), versus Blend.

- Brian

(Also I see that Blend does not work between the ends of one open curve, in either MoI3 or MoI4beta.)

Hi Brian, yup that's definitely a bug. It looks like it has to do with a new caching mechanism in v4. I'll see about fixing it, thanks for reporting it!

re:
> (Also I see that Blend does not work between the ends of one open curve, in either MoI3 or MoI4beta.)

Yes, you'll have to split a single curve into 2 pieces to do that particular blend.

- Michael

Hi Brian, also if that bug is getting in your way a temporary fix for the moment is to open task manager and kill the moi_commandprocessor.exe process before doing the blend again. That's where the old version of the curves are being cached.

- Michael

Thankyou Michael.
I'm working on 3D Euler "blending" of curve(s), if my math and programming is up to it☺
-Brian
It will be a clothoid in 2D.

Circle Tan and Arc Tan are not working on my work computer, but do work at home.
I'll check the error message more carefully tomorrow. I must have a missing helper script, maybe.
The error involves "GetPointOsnappedOnCurve.js", which is in the scripts #include statement.
- Brian

Hi Brian, yeah GetPointOsnappedOnCurve.js should be part of the default installation located at C:\Program Files\MoI 4.0 beta Feb-9-2018\commands\GetPointOsnappedOnCurve.js .

Is yours missing from there?

- Michael

I'm sure this has been covered before, but how (if) can I use my v3 .ini file and scripts with the v4 beta?

Thanks in advance.

Hi,

New Mac Wacom drivers won’t resolve the middle clicking issue (6.3.28.2).

I was wondering if there was any way to revert to the old way of two finger scrolling to zoom?
It may sound counter intuitive but I always use the pen's the middle button to pan.
The pinching method doesn't work as well for me.

Also, is there any way that Moi exports to the last used folder (of the last session)?
I always export temp stuff to desktop.

Marc

Hi Michael,
I re-installed Moi4FebBeta, over its previous installation, and all is well.

The file GetPointOsnappedOnCurve.js was present, but I think the problem was that in between the recent customUI upgrades, I had modified CommandBar.htm, which is no longer necessary for "AppData..." storage... Sometimes its better to "let the dust settle." :-)

So at work all of the stock Commands are under ProgramFiles/MoI 4.0 beta Feb-9-2018/commands

_prefix commands are in another commands directory a few directory levels below AppData..., but could be in the old commands folder. (I think)


- Brian

Thanks Brian! That did the trick!

Hi Michael T,

re:

Your moi.ini file should be used automatically unless you have some custom setup for it.

For scripts, any commands you added to v3's commands folder will need to be copied into v4's commands folder. With this latest v4 beta instead of copying them into the commands folder in the install directory, you can instead copy them into the new AppData commands folder which on Windows is at C:\Users\<username>\AppData\Roaming\Moi\commands, on Mac it's /Users/<username>/Library/Application Support/Moi/commands .

If you copy them to the AppData commands folder you won't have to copy them again when new beta releases come out since that's a centralized location that can be shared between multiple installs.

Hi Marc,

> New Mac Wacom drivers won’t resolve the middle clicking issue (6.3.28.2).

That's unfortunate. Hopefully with the next one. When I submitted the bug through their developer portal I got one notification right away that it was set to active status or something but I haven't heard anything else since then.

There isn't currently any way to revert two finger scrolling back to mousewheel zoom but I can add a setting for it.


> Also, is there any way that Moi exports to the last used folder (of the last session)?

There isn't any way to do this currently either but I can add in a setting for this too. Currently the default location will be whatever the operating system has set as the current working directory. On Windows there's a properties setting for shortcuts for setting the current directory for the program, it seems that there isn't an equivalent thing on Mac I guess.

- Michael

Hi Michael,

I've just installed the new Wacom drivers for Mac OS, and the issue where you had to left-click to activate a viewport seems to have been resolved. I can use the right mouse button to navigate in any viewport again by just hovering my pointer over a viewport.

That's great Metin - I wonder why it didn't work for Marc though.

- Michael

Thanks Michael, Brian straightened me out with the same advice.

Looking forward to running v4 through the paces!

Michael T.

Hi Michael,

Thanks, it would be nice to have those settings if it's not too much work.
Concerning the Wacom pen, it does work with right click, not middle click, kind of weird.

Marc

Thanks for all the great updates Michael - especially the curvature analysis script interface methods.

Some feedback:
Moving the the commands folder to %APPDATA%\Moi - is definitely a nice feature, but I wonder if the moi.ini file couldn't also contain one or more locations to search for external scripts? For some time I've been keeping all my scripts in Dropbox\MoI\commands, to enable the same scripts to be used from my (Mac) laptop via a Symbolic Link and (Win) PC via a Directory Junction. I appreciate I could easily make that Link and Junction 'just-one-last-time' now the new directory structure exists, but why not let a user specify one or more external script locations in the ini? It could also enable clearly separating beta scripts from full releases, or personal scripts from public ones, for example. Or is this what the %APPDATA%\Moi\startup folder can be used for?


And a question on script compatibility between v3 and v4:
I can't work out what change is required by the Script error thrown when I try running my NACA airfoil script in MoI v4.
"Required function argument 1 (object) missing."

Does MoI v4 require stricter adherance to Javascript best practices?

Any suggestions appreciated, thanks.
