Re: Plasticity 2025.1
The Y-fillet thing is built into Parasolid, so that seems like something that Onshape could add without too much heavy lifting.

Re: Straight loft
@uldema ..almost certain the issue lies in your sketches…. From the pic posted it's apperant the bottom sketch has an extra line segment to it. Make sure your sketches have the SAME number of points (bottom sketch has the same number of points as the top sketch), then Loft will behave properly.
Re: Petition to open the Parasolid kernel source code
Why should it be open source? So people can mess with it in their spare time? Rather than professional software developers to make a good product? Should software people get paid for their work? CAD used to cost 10's of thousands of dollars for one engineer to have a workstation and the software, in the 1990's. Now it's $1500 per year and can run on a $500 computer, It's dirt cheap. The people that want it for free, are they going to give away their time for free when they design stuff on it? Are they going to give away their products for free that they designed on it?
Money makes the world go around. Don't let anyone tell you differently. Without money as the motivation, open source projects will be limited to a few hobbyists twidding their thumbs on the keyboard.
Export multiple parts in a part studio to STEP files and retain part numbering?
Every time I export multiple parts in a single part studio, the export rules create a file name for each part that is [Part Studio Name] - [Part Name]. I want that to be [Part Number] - [Part Name] which is how I've set up the export rules for parts - when I export an individual part, that happens no problem. How can I do this if I'm exporting many parts at the same time?
Re: Can someone help me fix this model? It is simple - yet very broken.
Hi Dave. My version was an approximation to achieve the look. I left out some dimensions purposely for you to finish since they were not hard dimensioned in your sketch. Instead I was going for method. Note only 3 features in the list and all can be fixed as you see fit.
Re: Petition to open the Parasolid kernel source code
Siemens did give Plasticity a lower Parasolid licensing fee than they charge for MCAD stuff like Onshape and Solidworks. Plasticity is aiming more to compete with Blender, Rhino and Alias for modeling. It will likely get some light history so it can at least live update a loft or Square surface if the curves change, but it’s not going to have a complex feature tree or 2D mechanical drawing package with GD&T.

Re: Render Battle #6 - Coffee time ☕(Winner gets a real Prize!)
Since I don't drink coffee, I'm going to have to abstain…LOL
I love the realism of #4 but have to disqualify it for trying to game the system with distracting supporting objects. LOL
So since the render is really about the cup, I'm going to vote for #6 and its implied motion as being worthy of my vote. quite creative and quite impressive.
Just messing around Micheal btw… I really like yours too. 😉
#3 is just well really real. I love it. impressive
#2 I love inverted concept.
Combine #2 & #6 and that'd get my vote for sure.

Re: Petition to open the Parasolid kernel source code
@nick_papageorge_dayjob seriously? And you really think this is true?
Linux is widely used by professionals and many companies have built their products on it. Some examples:
Android, ChromeOS, Tizen,Snap Store are all professional software used globally and I dare say by yourself also.
Router firmware and embedded systems are found everywhere and are commonly based on linux. Devices like top set boxes and IoT switches are based on Linux.
IBM mainframes, Supercomputers, Smart devices and Network components often run linux because of their stability.
Klipper, a 3d printer management software, is totally based on Linux and it is opensource itself. Klipper is being looked at by quite a few 3d printing machine companies as their firmware of choice. Soon enough 3d printing will be mainstream for businesses and Klipper will become the goto firmware of all of them. Basically the whole 3d printing movement started out as opensource with RepRap, a bunch amateurs giving away their spare time for free, like Kevin O'Connor. He created Klipper in 2014 as a way to enhance the performance of his 3D printer by leveraging the computational power of a general-purpose computer, such as a Raspberry Pi, alongside the printer's microcontrollers
And last but not least, Ubuntu core is a minimal secure Linux OS used in Iot and edge devices for rubust management and deployment. Container-Optimised OS, or COS, is developed by Google for running Docker containers and this is based on ChromiumOS which uses Linux at its core. Google, you know that bunch of hobbyists twiddling their thumbs on their keyboards?
Yes money is the prime motivator, but it is also the prime suspect when you look at development stagnation, global inequality due to technology not being freely accessible.
And finally, when source code is open, you are safer! That is a fact! Closed software is almost always containing backdoors and bugs. Most bugs are first found by the open source community. And backdoors puts you at risk from greedy people and spying governments! All in all I do not think your arguments hold a lot of water.
