Remind me to stay away from that piece of junk - I'll stick with my MoI.

I'm trying to chamfer 2 edges on a cube in Plasticity and I can't figure out what I'm doing wrong.

I'm holding down shift when selecting the 2nd edge. With the 2 edges selected Fillet works ok but I get an error when trying to chamfer.

Geometry is just a boolean between 2 cubes created in Plasticity. ... ?

Work sfor me
but i have not taken same edges! :) So i must verify!

Same as you so I take 3 edges make the chamfer
then Delete vertical face
Not sure that will be the result wished! :)

Thanks Pilou, I'm just trying to understand why it isn't working on those 2 edges.

Like have I made a mistake in constructing the object, is it at some improper scale, is there some option for how the chamfers come together that should be set, or whether it's not supported or a bug.

Why does the fillet work ok on it but not chamfer?

It's just one cube booleaned from another cube:


Have I poked the wrong button in boolean or messed it up somehow?

Can someone build it from scratch does it do the same thing?

Some other real head scratchers

How do you make a cube freehand ? I mean just by drawing with the mouse instead of typing in sizes. I can get the bottom to be square but how do you get the height to be the same?

When picking the height of a box I can't seem to do any view navigation, what's up with that?

Are these things real or am I totally missing something?

I see there's a full-on diss battle going on here. Honestly, I don't get why you've personally jumped into this criticism. Plasticity might appeal to some people and not to others, just like Moi3D. I own both programs, along with Blender and a bunch of other 2D and 3D CAD software. Every app has its strengths and weaknesses, but there's no denying that Plasticity is an extremely powerful tool, and for someone like me who's used to Blender, the switch is pretty straightforward, they're just different philosophies and approaches.
Plasticity has made huge strides in a short time, and even the early versions could produce great models. It's only been around for 3 years, which makes it really young, even though it uses one of the most established geometric kernels out there. Plasticity already has a ton of features that people have been begging for in Moi3D for ages, especially when it comes to NURBS surface continuity, plus a proper advanced viewport.
I use both programs together in a complementary way: I do certain things in one and other things in the other, same as with Blender.
This field is growing fast and there are plenty of competitors out there.

Cheers

Hi pafurijaz,

re:
> Honestly, I don't get why you've personally jumped into this criticism.

I've just had enough of exaggerations and propaganda that Plasticity invented the concept of "CAD for artists".

That's just absolute nonsense.

I receive a lot of emails from people who have tried Plasticity and are confused why they found it difficult to use after seeing a lot of hype in YouTube comments that "it's pioneered a new category of CAD for artists" or they saw on the web site that "It's the easiest to use and has the best UX", etc etc etc but nobody seems to care about actual UX, the focus is all on having the coolest looking "modern UI" and trendy icons.

It's not just Plasticity that has this focus, Apple has pushed far in that direction recently as well.

I find it distasteful when I see poorly designed UX being praised.

For an already established Blender user, Plasticity is indeed a great UX fit and I have no issue with that.

What it is not is "easiest to use" and "best UX", and it is definitely not the originator of the "CAD for Artists" concept.

For whatever reason, probably due to my own extreme intolerance of marketing, there is little information out there for me to send to someone who contacts me and asks me for my recommendation and opinions so this thread will serve for that.

If I write something that is factually incorrect (for example if there is a way to enter the x,y coordinates of a circle's origin point) please feel free to post a correction.

The whole "CAD for artists" thing could just be marketing hype or a branding strategy, everyone makes their own business choices. That doesn't automatically make it untrue, though. The idea behind a "CAD for artists" is that, unlike traditional CAD software, it uses a direct modeling approach. I don't think the Plasticity developer ever claimed to have invented the concept of CAD for artists; he just said that's the direction he's aiming for according to his roadmap.

If the issue is that people keep emailing you to complain about another program, maybe you should just redirect their complaints to the right place and avoid taking on the stress of replying to folks dumping their grievances on you. After all, FreeCAD and Blender are complicated too, and don't get me started on gCAD3D, it has a terrible UI as well.

The fact that you're especially annoyed by Plasticity, but not by the hundreds of other apps out there, makes me think you might see it as a potential competitor. Otherwise, you'd be making long threads about tons of other programs too.

I'm not saying your points about certain flaws are wrong, but focusing on a few minor issues while ignoring everything else that's good about it feels like a gratuitous attack.

There are plenty of programs that people around here don't like, Blender and FreeCAD especially, but that doesn't mean they're bad applications.

I hope in the future the competition focuses on the features offered, rather than pointing out the flaws in everyone else's software.

Greetings.

There was a "cube" snap anchor long time ago (2y ?), a bit like in MoI, that feature vanished at one point and never went back (I haven't checked recent build). I wouldn't be surprised if there an alternative hidden key combo to create cubes, not sure tho.

I dont see any posts from hundreds of others software's being done in this forum here which belongs to Michael and MoI.... So Maybe you dont know how to read and interpret facts...

Lots of people singing the hype song though......

Maybe the guy who is proud of his accomplishments with regard to UX and maybe has a bad taste from others who RUINED his previous work, is pointing a few things out!

you were allowed to make your point. Starting to look a little like a dick now....

Yes if you poke me enough times eventually I will get annoyed! :)

@ Burr,

re:

For the record, I don't consider Rhino to be ruined, it's following a trajectory that I put it on myself.

It was designed with a focus on being friendly to AutoCAD users, a very different target than MOI.

That was a good fit for RMA since their work up until then was focused on being an AutoCAD reseller.

When the time came for them to exit the AutoCAD business they were able to switch fully to Rhino and didn't have to totally reset to a completely foreign environment.

Definitely different than what my understanding was….

So, noted.

Plasticity is the only one that started out by blatantly plagiarizing my work.

From 2006:
https://web.archive.org/web/20060810145302/http://moi3d.com/

"MoI (Moment of Inspiration) is a new 3D modeling/CAD program for designers and artists."


Or check out https://github.com/nkallen/elephant/releases/tag/v0.1-alpha where the entirety of MoI's UI and script commands were copied and forked as if it was an open source project.

They are not minor issues!!!!!

That drawing a circle is gross is not a minor issue!

These are the things that make the UX, not having stylish looking icons.

Yet there are so many people who are like "Ooooo sweet looking icons, I like how they all look like the same indecipherable blobs of monochrome lumps. A+++++!! Oh geez look at those icons, not monochrome, lame."

There are plenty of places that cover the good stuff (which is primarily that it is cheap).

There is not much covering the bad stuff, people are somehow scared to write their opinions publicly if it differs from the "influencer" horde.
