Load/Save to Cloud/ftp-server

DavidLyon66 — Fri, 28 Jun 2024 03:49:29 GMT

I'd like to have the ability to load and save files to Cloud storage, (or a local ftp server).

The reason is that if I'm working on a design and go away, I can't shut the computer down. It has to go onto standby.

After working on Microsoft Teams and 365, they force you to get used to using a Cloud. So unfortunately, the openjscad.xyz system feels a bit clunky in comparison.

Please consider at some point adding Cloud Load/Save if there is enough user interest.

Here's a discussion about a Javascript code snippet where something similar is implemented.

@Zachary-Keim good to hear. Guess it was a temporary issue 🙂

Unfolder V2, stress test on FF and Chrome

hrgdavor — Wed, 02 Feb 2022 13:49:43 GMT

@gilboonet that is excellent, it may be possible later on to integrate that one with jscad or at least take your experience for ideas how to improve 2D use-cases in jscad.

Unfolder script for V2

gilboonet — Wed, 05 Jan 2022 15:04:20 GMT

I rewrote my unfolder for JSCAD 2 and I'm very happy with the result. It looks almost like an application as user can enter the model file name and choose between options to see the model, scale it and see resulting dimensions, and finally choose several options for the unfolded pattern (paper size, flaps or not, exclude links, change flap attachment). I cleaned the code as possible and now it doesn't use global variables. It was the first time I used align() and it's a very handy function that allowed me to group small pieces. Due to the complexity of the script, it freezes after some time, I suspect memory leak but did not see where it could be. What would be nice with such script that has lots of parameters would be to be able to save/load parameters sets.

The project can be found here, unzip the archive into a directory, then run jscad and open it as a project. I added some 3d files, but you can test others by putting them into the project directory and open it with jscad. It can also directly run on a script, but to do so you must edit the code and change main() (this way it can run as a standalone script file).

Here's a link to a demo video

script using parameters doesn't render after some time

@z3dev Yes, add Memory would be great, I felt the difference when I changed from 4 Gb to 8. For the moment I'm simply starting to use my laptop as main computer.

Video of an integrated tool (from 2016) using OpenJSCAD v0.4

gilboonet — Fri, 10 Sep 2021 07:55:31 GMT

@jess-yan Hello, the point selection is made with an external tool, Openscad Simple Polygon Editor. I modified it so that I could use it along with OpenJSCAD. But it was with a very old version and with v2 I don't see how to do the same.

Compatible browser?

Update: This was fixed after I upgrade the chrome to version 90.
Thanks.

little script using external .obj

Finally I made it fit into one file using obj2jscad.js. It can be seen here.

Porting V1 code to V2 or rewrite it ?

gilboonet — Sun, 21 Feb 2021 10:46:21 GMT

@z3dev Thank you for your suggestions. What I did was only translating the code so it run on V2 regardless of placement. I'll try to implement helper function for cube and cuboid, then it should work.

I built a OpenJSCAD Gallery

We have been posting to this thread.

boolean operation produces non manifold

z3dev — Thu, 21 Jan 2021 10:21:46 GMT

Yup. The old fixTJunctions() function is not present in V2. There's a pull request to add this functionality back, which is under review now.

Can a html5 app running jscad retrieve rendered (processed) data ?

gilboonet — Wed, 22 Jan 2020 18:05:30 GMT

@z3dev Hello, I didn't open an issue because it's V1, but I will do it so we could keep track of the solution I used. Yesterday I tried my little html5 app on my android tablet with Firefox and it works perfectly

Design with random values

gilboonet — Wed, 28 Aug 2019 07:40:37 GMT

Thank you. I will try something similar, it just needs to add a parameter to choose a design number, if the table of random values doesn't have values for this number they are randomly feeded, else they are used for the rendering. Such "mechanism" could be handy for designs using both random values and more than one viewing mode.

Slicing again... simplifying code

z3dev — Tue, 13 Aug 2019 09:22:39 GMT

The simple solutions are always the best. Taking a super thin slice is a great idea, and maybe even the best.

The core library will be for core functions, as we expect others (like you) to contribute some really nice high level functionality, such as slicing. If we get the core library rock solid then anything is possible.

Projections on to arbitrary planes is on the wish list, but not there yet.

Thanks for the awesome posts!

slicing with OpenJSCAD

Hello,
With the same script and 3d model, I made a 60 cm tall statue with 200 sheets.

slicing with OpenJSCAD

gilboonet — Thu, 04 Jul 2019 08:08:18 GMT

@kaosat-dev At first I tried to use a 10K triangles model but as it didn't render I downscaled to 5K, 3K, 2K then 1K. And after, I made another model with 2x more slices that this script was unable to render even with a 1K model, so I changed the script to make it render chunks of slices, and it was ok. I suppose it could work with higher resolutions models.

Having trouble with variables in the Block design option

z3dev — Wed, 03 Jul 2019 14:11:32 GMT

It seems to me that the ‘Code’ tab in the upper right exposes the code in BlocksCAD. I was able to select and copy the code.

This new star primitive looks promising. Thank you for the code sample, I will try to use .fromAngleRadians().

Multicolor (by faces) model

gilboonet — Tue, 07 May 2019 19:41:54 GMT

My code (obj2jscad) only reads a very simple OBJ file (only triangular without normals or textures) and take use of its facets materials groups. Materials are described into another file that I don't use but it could be done to read colors as materials simplest expression can be colors. True OBJ format is much more complex than that.

Any ideas on measuring a section of an existing STL file?

z3dev — Wed, 20 Mar 2019 20:41:52 GMT

Of course, you can use the STL design to subtract from another design. Is that not accurate enough for your needs?

Measuring from point to point, or across a design isn’t possible. But you can always take a small slice of a design, and measure that using bounds.
