Plasticity: new software

ok champ, i must be seeing things wrong must be from that eye surgery i had my bad…..

but enough with the attention seeking being neglected im gona go and do some solidworks and complain why its not like paint in windows or something…

:smiley: I already explained to you that I spent the time long enough to figure out:

  • the many bad UI decisions in Plasticity;
  • the poor 3d mouse support in Plasticity;
  • how unnatural is to delete faces in Plasticity;
  • the inevitable leaving of the 3d mouse thousands of times per day to use the forced keyboard commands;
  • all the issues with fillets, especially fillets ending into a point;
  • the issues and crashes of the program that occur while moving faces in Plasticity (at least when trying to apply them on imported geometry made in Rhino).

Deleting faces is totally counter-intuitive. I know the function, but the implementation is bad. Just like being forced to hold the Power button and press Volume up or Volume down to set volume level on your phone.

I’m aware of the Parasolid kernel, especially the fillets in Solidworks. Super inaccurate fillets, leave gaps, create fake geometry, look totally different in Solidworks compared to when I import the model into Rhino. :smiley: I had to deal with plenty of customers’ CAD models made in various programs with the Parasolid kernel that exhibit similar issues, forcing me to fix them inside Rhino.

Hi @Rhino_Bulgaria

The gui is an analog to the “old” blender ui where the gui was mainly all hotkeys.
Because I use many programs this kind of gui has never worked for me. It’s simply too hard to remember after a period of time which hotkeys were which. However for people who use only that one program or who have phenomenal memory its probably faster. But; I can’t work this way I need icons and the one reason I gave blender another go is that they ditched that hotkey ui and made a more icon based ui. Why plasticity hasn’t followed Blenders example is because the ui is probably the hardest and most time consuming thing to code so by shortcutting they save themselves tons of work. Notice blender has an awesome ui that is totally customizable now, a far cry from plasticity.

It’s totally bad ui design to make the commands only accessible through the search function. I can’t believe they couldn’t make a menu of icons for all their commands.

I do have a copy and like it but I have to make my own menu with commands and there are some available for free or paid, It’s funny Plasticity claims “cad for artists” then stick all the commands behind a Chinese wall where no artist can easily find them.

Bah humbug…….

We all know it’s user error come on now :joy:

So if you know that parasolid auto filleting doesn’t fulfill your needs what do you expect? Plasticity will give you exactly the same output as all the others, they are no different in capability than the others.

And I still have the feeling you do not know or understand what the difference is between the two delete modes. Because pressing delete absolutely deletes things, just not in the same way as in Rhino - because this app is not Rhino.

I thought it was Tinker cad

You rely too much on your feelings about people you don’t know, instead of reading what I wrote above at least twice. Your statement is completely wrong. You are making random suggestions based on your expectation that the Parasolid behaves in the same way across all the CAD programs that use it. I have seen examples where the Siemens NX produces more stable results than Solidworks. On top of that, Siemens NX has custom solutions for complex corners where 3 or more edges are mixed together. An area where Solidworks fails most of the time - just like Plasticity, despite that all 3 of those programs use the same Parasolic kernel. What matters is the implementation of the latter in each of the CAD software where it’s included.

I gave another chance to Plasticity due to their bragging about the capabilities of the program. Turned out to be far less capable than advertised. Rhino’s own filleting tools are more capable in the complex situations. The Parasolid kernel has an advantage where it automatically chains all the edges that are tangent to the picked one. But that’s a minor advantage (Rhino also allows to chain select tangent edges) compared to the amount of failures that I experienced while trying to add fillets to some of my 3d models made in Rhino.

can’t because mac intel got skipped - sorry.

Well it does seem like you seem baffled by certain behavior that wouldn’t baffle you if you knew what direct modeling was. But sure.

But let me tell you this, that “deleting” a selection rips a hole into your solid body and converts it into an open poly surface is not expected behavior for most people modeling with solids.

Personally I think the biggest weakness of Rhino’s filleting is simply that you have to guess the values and that there is no live preview. That’s the thing that actually makes it feel like a 90s software.

you 100% can preview fillets in Rhino and change the values as they update the preview.

I recommend you to learn Rhino before you claim false statements about it.

As for the “conversion” of solid models into an open polysurface… Well, guess what? My models were already open polysurfaces, so deleting a surface does not matter at all. Not to mention that Plasticity is widely used as a surfacing program with ton of models that are open polysurfaces. This is not an excuse for the counter-intuitive implementation of the UI.

Friends? Bummer.…well I guess I’ll cancel this order from Amazon for now

I don’t count this as a live preview because I still need to manually type different values under set all - which is the opposite of what I expect from a fillet live preview and defeats it’s purpose: defining the fillet visually.

Have you considered that direct modeling also works on surfaces?

you can run preview = yes, set all to start values and then drag the fillet handles… it is in fact interactive and live.

But only one handle at a time. I basically never need variable fillets, I want to interactively define the global radius of all fillets at the same time.

You can set a single global radius from the command line. Alternatively, use the new interactive filleting tool in Rhino 8.

Variable fillet is an extremely useful feature in Rhino.

This is what I teach you in my previous post.

You can set a single global radius from the command line. Alternatively, use the new interactive filleting tool in Rhino 8.

As I said… I do not want to type numbers in a command line, I want to dynamically define my fillet and make a decision visually. This is something Rhino cannot do. And not out of technical limitation but out of UX nonsense where someone made the decision that interactive fillets are only available for variable fillets and not for “normal” fillets. Fillets just need an overhaul from scratch in Rhino and be pulled into the 21st century where they don’t blow up the mesh in the most trivial cases and a UX that doesn’t have a 3-layer deep command line interface.

Completely besides the point, lol.
