Mesh Align Plus, News/Announcements

(egtwobits) #36

Meta-Androcto, I have some work-related things going on in the next few days, but I’ll catch you on IRC sometime soon.

BTW, if anyone has difficult alignment problems to discuss, please see this thread about sample cases.


(egtwobits) #37

New feature, multi-object editing (use this link, same as above, to test it out):

This applies the operator to each selected object. The active object is used when ‘Auto Grab Source’ is checked (so it will yell at you if you try to auto grab source verts and there’s no active object). As always, please share any thoughts/feedback.

Finally! Looks like Blender is getting some alignment or snapping tools that Wings3D had over 10 years ago!

(Now if only somebody can figure out how to make the MMB sticky for rotating the view, and allow to pause a mesh manipulation operation right in the middle in order to change the view to a better vantage point before continuing and completing it…)

But yeah, this looks very useful. Particularly when you’re trying to do stuff with fits that don’t lie along the usual global axes. I think I’ll have to mess around with it to see how well it works.

How do two objects of different sizes overlap?


(obsurveyor) #40

One thing I’d like to suggest is some way to click to sample the plane normal you’d like to use instead of having to enter edit mode and picking a face or 3 vertices. The “Carver MT” addon now included in 2.78 samples the face the mouse hovering over when you’re using the Profile Brush so that may be somewhere to start looking if you don’t know how to do this.

Also, shouldn’t this thread be in the Released Scripts forum, not Latest News??


(egtwobits) #41

New release! Grab it here (v0.3.0) now. Also, I took your suggestions and made a new thread in the Released Scripts subforum. The goal will be to have in-depth discussions there, and keep this thread focused on News related announcements (like new releases).

obsurveyor, I’ll look into adding some version of a feature that will let you easily grab the face normal.

jack1940, I’m not sure exactly what you’re asking, head over to the other thread if you want to discuss more or message me.

Wondering is it possible to add a relative Rotation?

which would require to first save a rot angle value as reference
but also be able to come back to that rot angle if needed

then do some rot of specific angle value
PM me if you need more details

Happy bl

Check the GIF below, it is literally the exact operation I last posted about on the other thread :slight_smile: It’s an in-development feature right now, so you’ll have to grab the latest testing version of the addon (I’m planning a release soonish).

Testing version here (Save as or paste page contents into blender text editor and hit run script…disable any previous versions first also!)

New release, v0.4.0!

Download v0.4.0 here:

The new (GIF loaded) wiki:

Youtube Video:

Huge upgrades were made to advanced editing and measurement features. These improvements mean faster, more flexible and more lightweight workflows for complex operations. The Wiki has also been completely rewritten for this release (now on Github).

Very cool, I am sharing this asap to get the word out


(jachtarfranko) #46

I very like your addon, this is much more better align than in my CAD application.


(unkerjay) #47

This seems far more granular than what I tend to want to do. For my purposes, Align by Faces (also an addon), is mostly what I need.

When that doesn’t work, or I need more, more control, (and it looks like, with more control, comes more complexity), Mesh Align Plus would be my goto tool.

Seems confusing because “mesh” can be a vertex (vertices), a face (faces), or an edge (edges). And as such, maybe it’s me, your tool seems a little unclear in that regard.

Looking at how vertices align based on the examples I’ve seen here, wasn’t what I was expecting.

Align by Faces was what I was thinking would happen.

Seems, like some extra mental effort is involved if “Align by Faces” is what’s preferred.

Again, maybe I missed it. I didn’t quite see a clear, straightforward example of that.

Other than that, looks quite powerful and versatile as long as you understand how it works and why.


Looks like there’s more info (and gifs) on this at your GitHub.

Helps to spell it out a little more clearly.


To be clear (since there is more than one location), here’s where I found my answer:


(Sackadoo) #48

I’m just discovering this because the update post brought it to the ‘front’ again. Which made me wonder: Couldn’t there be a place on BA where a person could go to see a list of announcement threads like this about addons, important insights into Blender or what-have-you? Someone new to Blender—or someone returning after a long hiatus, like me—could easily overlook such a powerful addon because it’s buried.

Food for thought for the BA admins? Or perhaps the thread system doesn’t support this kind of thing?


(egtwobits) #49

It’s good to hear when people find your tool useful, thanks for posting Craig Jones, jachtarfranko, rontarrant.

Unkerjay, I updated the reference manual on the wiki to explain more about how Quick Align Planes (face to face alignment) works (Answer is that selection order of verts determines the final orientation of the planes, where the first 3 selected define points A, B and C. B is a pivot, and A determines how the target is rotated after coplanar alignment. So, if you want two similar things oriented the same way, grab in the same order/handedness):

About the name, the word Mesh is supposed to refer to Mesh Objects as well as actual Mesh Data. It’s difficult to fit everything into a name that is descriptive, accurate and catchy!

If there are other things that I can help explain about how things works or why, please ask questions because I’d be happy to answer them. I spent a long time on the rewrite and GIF’ening the wiki/manual on github, so if you haven’t read that yet then hopefully you will find the information there helpful (the wiki home page especially):

Reviving the existing news thread to make an announcement:

New v0.5.0 release is out! Install notes are here. Check out the in-depth discussion thread for more info in the released scripts subforum here.

Blender 2.80 compatibility, a new face-alignment option (and default behavior!) for “Align Planes” and a NEW INSTALL PROCESS are the big headlines with this version of Mesh Align Plus (free and open source as always!). The addon has now moved to the 3D View > N panel as well.


(eobet) #51

What a life saver this add-on is!

And it’s even more flexible than the last one I used for 2.79 (it was called “precise align” and it was years and years out of date but I kept holding on to it).

Super happy surprise to search and suddenly find this now that I’ve switched to 2.8. This should be included with Blender by default. Fantastic design! Wonderful job.


(egtwobits) #52

Thanks! If you’d like to share thoughts about features for future releases, they’re always welcome…

I do actually:


(I’m second guessing myself now, but I think I want to keep the mesh in place and only move the origin and the object’s local axes. Maybe this is already possible, and if so, I apologize, but it’s not immediately clear how to me. This would at least be an UI improvement from my point of view.)

Maybe a quick option to put a face of the object “on the floor” (XYZ=0, face normal pointing to -z). this way it’d be easier to rearrange misaligne objects on a scene.
It’d also be very useful when dealing with models for 3d printing or scanned objects


(Nomo) #56

I wonder if the align function could be possible without going into edit mode like maya’s Snap together tool. It would make the tool much more intuitive and accessible.
