Re: Petition to open the Parasolid kernel source code

https://forum.onshape.com/discussion/comment/114678#Comment_114678

As far as I know, PTC has never licensed their Granite kernel. When Onshape started (long before being acquired by PTC), there were only a few realistic options, and Parasolid was also what the team had used when they started Solidworks.

Re: Petition to open the Parasolid kernel source code

Not exactly. Unix was develloped by ATT and at some point distributed to universities so students could work with it. This started innovation because the students improved and made new things with it and for it, It was never made opensource as such. Linus Torvalds created Linux totally from scratch from the ground up. There is of course similarities because Torvalds was inspired by Unix and the fact it was distributed to universities. This might have been his largest inspiration to create something that was truly open and accesible for all.

Since its releases of subsequent versions, many companies took Linux as their core computing kernel. These companies are all for profit and operate in our economic climate, and some very well you could say. So to state that money turns the earth around is true of course, but it does not mean that if some source code is open, the economic dependencies break and people do not want to work with it. In fact it is the opposite, linux has developped a whole new business based on opensource computing.

Examples are:

Red Hat which developped RHEL, Red Hat Enterprise Linux. Now a standard in enterprise environments

IBM who made their own distro called LinuxONE

Intel focussed on chip compatibility and open source drivers. They also contributed to the kernel development

Canonical, this is the company behind Ubuntu, which is now one of the most popular desktop distro and has some server distros also

Funny enough even Microsoft contributed with their Hyper-V virtualization tech.

All in all the history of Linux shows that opensource promotes development, innovation and helps new businesses. Personally I do not accept that computer code is a product for sales. I see computer codes as tools that enable bright people to come up with good things that help everybody from business to government and individuals. Take free code and make a new product with it and sell that product. Make a service package that includes many innovations which are closed off and protected by patents but use free source code. Nobody in their right mind will argue that it will be "stolen" as such. It truly helps innovation like nothing else while it does not hamper businesses.

Think of another aspect of this, peripheral devices!Is it not annoying that you can still buy computer mice, like the 3dconnexion space and cad mouse, that simply do not work in certain environments? If the source code was all open this would never happen at all.

Yes I am a great fan of opensource, not because one can have free stuff but because I am convinced that it will be part of a new revolution in computer tech. All this protectionist business is old hat (for code). Economies do not do better because of it, it hampers them.

Re: STL Import can not select edge geometry

if the stl is watertight, you can cut/split it and use the contour lines in a sketch.
if the stl is open, you get errors, but can still cut/split it. and use the lines in a sketch (and get more errors). using these allows for use of the fill feature.

Re: STL Import can not select edge geometry

Same problem here. I can only highlight the entire surface and the edge. The problem is not in the file.

STL Import can not select edge geometry

Hello!

I am trying to import an STL file to be used as a solid body. When I import, onshape recognizes and imports the STL as a single surface with one large open face; however, I can not select the edges of that face for any of the "fill" surface modeling tool. Despite this, I can still select the edge when I am not in a tool menu, but as soon as I try activate the tool and try to select the edge, the edge is unable to be selected.

Is this an issue with the STL file? Is this an issue with the import?

Thank you for any insight!

Re: can I add extra truetype fonts to Onshape?

i suppose you could write all the letters in solidworks or whatever. Extrude it and import into Onshape.

Then make a new sketch for each letter. Make a featurescript that accepts a partstudio with all of your letters. Then a text box and a height.

Have the feature replace/scale each sketch with each letter in your textbox.

similar to how beams can read sketches from other partstudios/documents...
