A new v2 beta (version Dec-19-2009) is now available for download here:
http://moi3d.com/beta.htm

You will need to enter your v1 license key to download the v2 beta.

The v2 beta installs into its own folder, it is not a problem to have v1 and any v2 beta installed on the same machine, in fact I recommend that so that you can fall back to v1 if you run into some temporary bad bug in v2.

This is very close to the end of the v2 beta period, but there will still be one more beta to fix up some bugs in some of the new features in this Dec-19 release.

Please let me know if you run into any bugs in the new features so that they can get fixed before the v2 final! The only area that is still actively in progress and known to still be buggy in this release is the new corner mitering for 1-rail sweeps especially on curved rail segments.


New stuff:

New set of object orientation and matching tools to make it much easier to position objects relative to one another.

There are 6 new related commands that make up this toolset: Orient, OrientLineToLine, OrientViewToView, CopyClipboardWithOrigin, PastePart, and ImportPart. The first 3 are available under the new Orient button under the Transform palette, and the others are available by a right-click on existing Edit > Copy, Edit > Paste, or File > Import buttons.

Some demos:

Here the Transform > Orient command is being used to reposition a cylinder along the side of a pyramid shape:


Here Transform > Orient is being used with the "Make copies" option enabled to position some text onto a box:


Here PastePart (Right-click on Paste or Ctrl+Shift+V) is being used to paste in the contents of the clipboard to an orientation aligned to an existing object, note that you can align not just to planes but also to the normal of a curved surface as well:


With the Clipboard and File import variants, you only pick the target orientation because the base orientation was specified at the time the object was copied or saved to the file.

Another example of PastePart:



Another example of PastePart with the target rotation being manipulated with several axes:


If you click on an axis instead of drag on it, it sets that one as the "primary axis" that the others will rotate about when you drag on them, the primary axis is marked with a little dot at its end.


These tools greatly simplify what would have previously required many separate applications of the Move and Rotate commands.


Some details on the individual commands:

Transform > Orient: Select the objects you want to reposition and then run this command, it will then prompt you to pick a base orientation and then a target orientation. The orientation picker is the same UI that is used to specify an orientation for the View > CPlane command as well.

Each orientation pick involves 2 steps - first you pick the origin point which automatically aligns itself to surface normals unless you disable the "Align to objects" option. Then you can adjust the rotation by dragging on the axis lines. If the default initial rotation is fine, then just right-click or push the "Done" button to accept the default rotation.

So for simple placements where you don't need to adjust the rotation you will do 4 clicks total: 1 click to pick the base origin point, 1 right-click to accept the default rotation, 1 click to pick the target origin point, and 1 more right-click to accept the default target rotation.

You can click the "Make copies" option or hold down the Ctrl key when clicking the target origin point to drop copies of the selected objects and keep the original in place.


Transform > Orient > Orient Line to Line : This command is more focused on 2D orientation, you pick a 2 points to define a base line, and then 2 points to define a target line, and the objects are moved, rotated and also scaled to match the first line to the second. For example here it is used to transform a curve so that its endpoints match up with the endpoints of a different curve:


There are options to disable scaling, switch to a "stretch" type scaling in one direction only, and to make copies.


Transform > Orient > Orient View to View : This allows you to remap objects from one view to another. You do one click inside the source viewport (anywhere in it, it doesn't matter on which specific point), and then one click in the target viewport.

So for example if you have imported some 2D curves that are flat in the Top view, you can use this command to quickly shift them to be flat in the Front view instead (same as rotation by 90 degrees but without needing to go to some other side view). Also when you click in the 3D view as either a source or target view it will be the current camera's view direction that is used for the orientation.


CopyClipboardWithOrigin - this is available by using Ctrl+Shift+C (additional Shift key held down instead of just regular Ctrl+C) or by right-click on the Edit/Copy button. It copies the selected objects to the clipboard like the regular Ctrl+C but also prompts you to pick an origin point so you can set the base origin position of the copied objects, which will then be used by PastePart later.

PastePart - this is available by Ctrl+Shift+V or by right-click on the Edit > Paste button. It pastes in the contents of the clipboard but also allows you to pick a target orientation to position them instead of just placing them into their original locations like the regular Paste command. The base orientation can be set by using the companion CopyClipboardWithOrigin command, or if you had done a regular Ctrl+C without the extra origin pick, it will use the CPlane that was set at the time of copying (default is the world origin and world axes) as the base position and orientation.


ImportPart - this is available by right-click on the File > Import button. It is similar to PastePart except the objects get sucked in from the file you pick rather than from the clipboard. The base origin is defined by the cplane that was set in the saved file, or the world origin if no custom cplane had been set.

If you have some objects that you want to frequently bring in and reorient, you can set them up into their own separate files and use ImportPart to bring them in as needed. You can also set up a keyboard shortcut with the filename given to ImportPart. To do that set up the Command part of the keyboard shortcut like this:
ImportPart c:\some folder\myfile.3dm
that will then let you bring in that particular part by using that shortcut key, bypassing the file dialog. So for instance if you use 3 parts really frequently you may want to set those up into separate files and set up

Aha this is amazing :D
Transform orient is just great and look so simple to use, I cant wait to try it :)
Now I want a "components" library like in sketchup and been able to take them from the library and Transform orient them into place !

Nah im kidding its already a great new release.
Thanks for all the work Michael, and merry christmas !

runs off to test the new beta

Hi DesuDeus,

> Transform orient is just great and look so simple to use,

Yeah, I'm really glad to have that area covered now, it was previously a pretty big missing thing.

It's kind of the culmination of some UI concepts that were prototyped for the View > CPlane command much earlier on in v2.

Someday I'd like to have that, but not for v2! :)

But you should actually be able to set up some libraries just by making your "component" to be in its own 3DM file positioned around the origin, aligned to the world z axis.

Then you can use the new "ImportPart" command (right-click on File > Import) to bring it in and place its orientation pretty much like a component.

The main part that is missing from that is that it won't be an actual "instance" that would get updated when you alter its definition. But as far as assembling things together from library building blocks, it should work pretty well for that type of thing.

Let me know if you want more details on how to set it up. But it's pretty straight forward...

- Michael

Thanks Danny!

So some chunks of that new orientation stuff come from that previous discussion where you had asked about using separate instances of MoI and cplanes as a way to do a kind of separate "part modeling" + assembly type approach. (back here: http://moi3d.com/forum/index.php?webtag=MOI&msg=2599.17)

So hopefully this new feature set should enable that kind of workflow that you were asking about there, it would be great to hear how it works for that when you get a chance to try it!

But the other good part is that the toolset seems to be complete enough to enable other things as well, like making library "part" files to import and place onto objects, and just transforming objects within a single model.

It also should be integrated with cplanes in several aspects, like if you have a cplane set then it will become the base reference frame of the part when copied to the clipboard with a regular Ctrl+C, or if you copy with Ctrl+Shift+C to set the base origin point, the axis directions will still come from the current cplane. Let me know if there is any type of cplane integration that is missing.

I think as a set it should allow solving a variety of similar problems in a cohesive way, but I'm interested to hear how it feels to others in practice though...

Here's the script copier utility for this new Dec-19-2009 beta release.

You can download and run this utility which will copy over any custom plug-in commands that you may have added in MoI v1 over to the new v2 beta's install folder.

It's just a shortcut for copying files from the v1 \commands sub-folder to the new \commands sub-folder.

Excellent work Michael,

>> ImportPart

You could implement this feature in the Objects tab(or Groups)in the browser,
making the part easier to find.

Mary christmas,

Hello:

Definitively, I can´t understand how works the Flat parameters in the Sweep command.

Any tips, expamples, explanation...?

Another cuestion:
How can I use the ArrayGem command?

Anoher one:
I´m sure that it´s a mistake from me, because I´m used to draw in AutoCAD and his layer managements, but.....how can I change a Style for define it like a default Style?

At the end (off topic):
I can´t see the images in Firefox.
Before, I couldn´t see directly them, but I could pick over the name and then load and see them, but now even I can´t see the name of the graphics files. There are only a small square. There are no problem with IETab (IExplore 8)

Thanks in advance!

Hi David,

Well, first of all there is a bug where the "Set flat direction" can show up with 2-rail sweep when it is not supposed to, it only applies to 1-rail sweeping. So ignore it for now if you see it when doing 2-rail sweeping.

With 1-rail sweeping there has always been (since v1) the option to set the Twist parameter, which controls how the profiles rotate as they travel along the rail path.

That's actually covered in the regular help file entry for sweep here:
http://moi3d.com/1.0/docs/moi_command_reference7.htm#sweep

When you set "Twist: Flat", the profiles will only rotate around the world z axis direction and not "bank" left or right around the rail tangent unlike "Twist: Freeform".

The new "Set flat direction" button allows you to pick 2 points to define the rotation axis direction, previously this was fixed to the world z axis but now you can adjust it to suit something like a helix that is not aligned to world z but is pointing in some other direction.


> How can I use the ArrayGem command?

You have to set up a keyboard shortcut with ArrayGem as the command part of the shortcut in order to launch it, there is not any toolbar button for it yet.

Do you mean that you want to set something like the "Current layer" in AutoCAD? I mean set which layer is applied to newly drawn objects?

For that you set the "Active Style" in MoI - go to the Styles section in the Scene Browser, and Right-click on the color swatch for the style you want to make active. It will get marked with a ring around the outside of its color swatch. After that newly drawn objects will use that style.


> I can´t see the images in Firefox.

You mean here in the forum?

Hmm, you might try clearing cookies - in FireFox this is under Tools > Clear Private Data.

Also try using the following link which will clear out cookies specific to the forum and may help to reset your login session:

Hello Michael:

1.- I think that I had an accidental non-desire situation.
If I draw any closed curve, and a path touching the curve, and after that I apply a 1 rail sweep-->Flat-->Set flat direction and I choose a diagonal direction I get a weird result. How this was the first example I was searching, I was coming back again over the same, and I was forgotten the original sense of "Flat" parameter.
I put a image for explanation. Don´t pay attention to the other lines, I only was testing things.

2.- About ArrayGem: Thanks, I saw your notes after. I always ask the questions and after read about that :-(

3.- About Active Style, very thank you! I´m sure that there are any note from you before, but.....(see 2 paragraph) :-)

4.- About images. I don´t know how and why, but I had blocked the images from this site. I had this problem 2 months ago...anyway..fixed.

Bye!

David

Hello again:

Following the Sweep command-->1 rail-->Flat....¿looks that the final solid is more wide than the original profile.?

Hi David,

> ¿looks that the final solid is more wide than the original profile.?

Yes that will happen if you set the Twist option to 'Flat' on a profile and rail combination you've drawn there, and if you've set a Flat direction at some random angle you will get unpredictable results for that combination. If you leave the Twist option to 'Freeform' you will get the consistent shape of the profile along the rail.

Why do you want to use the 'Flat' option for this, what is it you are trying to achieve? the Twist 'Flat' option also means force direction, so when you choose a direction the twisting of that profile will be forced in that direction.

Here is a short video showing what Michael has explained above about what "Set flat direction" is used for.
Say I want to model a simple spring at a certain angle, you'll see a simple helix and a square profile, the helix is at 45° to the 'Z' axis, in the previous versions of MoI you had to have the axis of the helix the same direction as the 'Z' axis, apply the sweep with Twist=Flat then rotate the model 45°.
