Generate button broken in Safari on OSX

At least one recent version of Safari works fine until attempting to generate STL or any other format. Clicking the button results in no action, and nothing in the browser console.

cannot set variables inside a loop

Great to see I can set a variable inside a module - now need to be able to set a variable inside a loop

XML has incorrect namespace

Exported XML files have the namespace declared as

xmlns="http://www.w3.org/1999/xhtml"

but this is not XHTML and the document is thus not rendered by a browser as XML

Suggest removing the xmlns attribute altogether or giving it a URI appropriate to BlockSCAD eg
http://blockscad.einsteinsworkshop.com

Strings not handled corrected as parameters

creates this openSCAD

module makeText(label) {
linear_extrude( height=10, twist=0, center=false){
text("label", font = "Liberation Serif", size = 10);
}

}

makeText(hello);

but it should be

module makeText(label) {
linear_extrude( height=10, twist=0, center=false){
text(label, font = "Liberation Serif", size = 10);
}

}

makeText("hello");

Can't Save From Samsung Note 10.1 2014

Samsung Note 10.1 2014
Chrome Browser

Was able to log into my account. Created an object. When I tried to input a project name the keyboard got stuck in the text window. Refreshed the page which worked: kept the blocks, kept the name, got rid of the keyboard. But I could not save my project nor interact with any of the top bar menus.

Match OpenSCAD features

There's a number of features that we're missing, and if we want to be fully OpenSCAD-compatible, we need to add them.

Working from the OpenSCAD cheatsheet, just looking at shape generation:

• Projection
• Minkowski Sum
• Children
• Resize
• Offset
• Polygon
• Polyhedron
• Surface

blockly/msg/json/en.json parse error when building blockly components

Heyas,

On my system I'm seeing a python error when running build.py in the blockly directory on the development branch (commit 58a2fdb):

Error reading ./msg/json/en.json
Traceback (most recent call last):
  File "i18n/create_messages.py", line 149, in <module>
    main()
  File "i18n/create_messages.py", line 65, in main
    source_defs = read_json_file(os.path.join(os.curdir, args.source_lang_file))
  File "/home/anomaly/devel.hosting/BlocksCAD/blockly/i18n/common.py", line 64, in read_json_file

The python json parser doesn't seem to like the stray commas after the final properties in a list. Changing this

                "locale": "en",
                "messagedocumentation" : "qqq",
        },
}

to this

{
        "@metadata": {
                "author": "Ellen Spertus <[email protected]>",
                "lastupdated": "2015-09-15 10:09:56.877000",
                "locale": "en",
                "messagedocumentation" : "qqq"
        }
}

resolves the issue. My system is using python 2.7.3 (Debian Wheezy)

Rendering fails when defining a variable inside another block

How to reproduce

1. Create a new project
2. Add a block that can contain other blocks, e.g. a "sides" block
3. Add a variable-defining block with a variable and a numeric value inside the "sides" block
4. Click render. The rendering will fail because of Syntax Error due to a missing semicolon

Example Blocks-xml-file

<xml xmlns="http://www.w3.org/1999/xhtml"><block type="$fn" id="1279" x="-83" y="67"><value name="SIDES"><block type="math_number" id="1280"><field name="NUM">8</field></block></value><statement name="A"><block type="variables_set" id="1327"><field name="VAR">some_var</field><value name="VALUE"><block type="math_number" id="1348"><field name="NUM">42</field></block></value><next><block type="sphere" id="1359"><value name="RAD"><block type="math_number" id="1360"><field name="NUM">10</field></block></value></block></next></block></statement></block></xml>

sides block - assign is being deprecated in openscad

using blockscad code in openscad reveals that the assign function is being deprecated (due to their new variable handling). We use that for our sides block and need a move forward plan.

Naming Objects

I would like to be able to assign (programmatically) names to objects and have those names be used when exporting to X3D, STL, ... where the export formats support names, so that I can more easily reference the objects in X3D.
Support for the animation capabilities of X3D would be great as well.

Support the projection() function, or enable transforms and Booleans of 2D objects

Yes, one can export a DXF, but I don't see how one can make something worth exporting with only 4 objects and text --- if I'm missing something, please let me know.

Change default scale / unit

Hi devs!

I'm trying to play with the tool to design a shipping container house. I've found some 20ft and 40ft container models and imported them in my new project (.stl files). Unfortunately, it seems the default unit is millimeter, while the container are respectively 6 and 12 meters long. Thus the rendering is way too much zoomed and unzooming it leads to losing the image as it's probably out of bounds.

Is there any way to change settings either globally or for the imported blocks?

Generally speaking, is there any help to learn about the different blocks and functions?

Thanks in advance fro any clue!

Viewing controls missing

Rotation works fine but I can't see how to zoom or translate

Exemples not working, not displayed when offline use

Hi,
I've downloaded BlocksCAD (version 1.7.3) here in order to use it without Internet connection.
When, I want to see or use the exemples provided, nothing happens : nothing is displayed.
No problem when I use the site https://www.blockscad3d.com/editor/?lang=fr#.
Thanks for your help, regards,

Non-manifold STL

The simplest union of objects creates STL which RepetierHost judges to be non manifold. Generally slic3r can handle these but not always, and cleanup via say netfabb would be tedious. The equivalent code in OpenSCAD has no such problem eg.

cube(10);
translate([10,5,0]) cube(10);

Collaboration with OpenJSCAD.org

It seams that this project is making some changes to common libraries which both BlocksCAD and OpenJSCAD.org are using. How about some collaboration on these libraries, which can benefit both projects.

Variables confuse cylinder radius locking

When a variable is placed into either radius slot of a cylinder block, the radius-locking functionality no longer works.

While the lock is active, I'd expect putting a variable into radius1 would make a dimmed version appear in radius2. Failing that, I'd expect inserting a variable to forcibly unlock the cylinder, to make it clear that the value isn't getting carried into the second slot.

README allows localhost but fonts missing and setting offline with undocumented edit

"Error: Failed to Load Font:" when using TEXT on Ubuntu Studio localhost.
next issue is error
blocscad.js needs to be set offline true as revealed by phone call to developer
Blockscad.offline = true; // true unless using a cloud service backend for file management

render error in line40 [uncaught DOMException]

sometimes happened to me in Chinese languege.

Orthogonal View

It would be really nice to have an orthogonal view mode.

Calculating with angles

When I take a Rotation block, it has an Angle sub-block. If then then want to multiply that angle by a certain factor, I take a multiply block, insert it into the Rotation block, instead of the Angle block, and then take the Angle block that fell out into the Multiply block. Then I add a number block as the factor, or some variable block as the second multiplier. But this does not work, a multiplication only wants to operate on numbers, not on angles. 5*10°=50° does not seem to work. The workaround I have found so far is to use a number block instead of the Angle block, and write the degrees as a number in there. Then the multiplication works. The disadvantage is that I cannot graphically select the angle anymore.

Generate Button

Generate Button and the view frame are not showing up in Chrome Version 51.0.2704.106 (64-bit) running ubuntu 14.04

Arrays

We really ought to have support for arrays. It probably makes the most sense to base it on Blockly's List blocks.

Unable to set variables in module

I want to compute local variables based on parameter values but attempts to add set variable blocks to a module are rejected although the obvious OpenSCAD code (with or without assign() ) is fine.

This is rather important when developing good programming practice. Without it you end up with lots of meaningless duplicated numbers and expressions.

Extend BlockSCAD to allow use of the Customizer Interface

I really enjoy BlockSCAD --- it's made me far more productive in OpenSCAD --- Thanks!

But the one feature I use which it doesn't support is the Customizer --- it would be wonderful if one could directly support it in BlockSCAD and that when OpenSCAD code was created it would be compatible with the Customizer (I add comments to help it, but I always have to edit the underlying code).

Internationalization

This is fantastic, the power of OpenSCAD with the ease of Scratch!

I would love to teach 3D modelling to kids with BlocksCAD. Is it translatable already? If not, how could we get it there?

BlocksCAD to OpenScad shifted text

Screen shots of 3D text on modified cube reveals a shift when save as SCAD is used.

STL(binary) appears correct in Mesh Lab.

Notice second line is also shifted from G over N

Import .scad-File!?

I think it would be nice to have the possibility to import .scad-Files - or is there already a possibility to do this?

Unable to delete individual blocks on development branch

After checking out 58a2fdb the dropdown menu for blocks only contains 'disable all blocks' and 'enable all blocks' and no longer shows the option to disable individual blocks nor delete them.

Non-manifold issues with simple geometry

Some simple geometry results in non-manifold STLs - example attached. Looks like some bad triangulation. All earlier versions of BlocksCAD show this issue, as does the current version of OpenJSCAD. OpenSCAD 2014.01 produces perfectly fine STLs.

Model is not on a closed surface

Hi,

I want to point a bug I found using a model I created today : https://www.blockscad3d.com/community/projects/43698

When I tried to export this model in STL format to my 3D printer I got the message : "Model is not on a closed surface"
And when I try to print this model it fails. I also have trouble when i try to import this STL model in tinkercad,etc it bugs.
Perhaps the problem is in STL générator ?

Indedd, I take the code of this model and I copy/paste it in opensCAD software and when I export the model in STL it works fine on my printer.

Best regards

Christophe

how to generate language files? I want to translate the soft into Chinese

I can use "js_to_json.py“to generate zh.json, and then modify it. At last, use "create_massges.py" to generate zh.js.
But, after that, there is no changes on the webside.
please tell me the right processes to generate language files.

Newest version ?

Hi,

First, thanks for your work an your sharing.

I'm a teacher and I've downloaded the BlocksCAD here for an offline use (no Internet connection in the school room) in order to print parts with Cura and Octoprint on a Raspberry Pi 4 (project here in french : https://lofurol.fr/joomla/impression-3d/142-imprimante-3d-anet-a8-pilotee-sous-primtux6).
It seems that this is an older version in the git repository (1.7.3) than here https://www.blockscad3d.com/editor/?lang=fr# (Version 1.13.0, 2021/03/31). So is it possible to download a newer version and where ?

Thanks for your help, regards,

Thierry Munoz

I want to try to add blocks with the rest of OpenSCAD 2D command, should I?

using variable in sides block gives NaN in generated code

declaring a variable and then using that variable in the sides block produces illegal code like:

item = 10;

assign($fn=NaN){
}

recursion not supported in modules

recursive call in a module generates a syntax error even though the resultant OpenSCAD code executes correctly.

auth.js referenced but missing

It seems there's a file missing from the blockscad/ directory, auth.js. If I try to build the 'core' with the reference to the file removed, the resulting application is a bit broken. I've checked on several branches (standalone, development, master) and the result is the same in each - if I rebuild without this file I am unable to render or create projects

Integration with nicescad

nicescad (demo at http://nicescad.bitplan.com/) tries to integrate different Open solid 3D CAD solutions e.g.

• openscad
• openjscad
• python solidpython
• blockscad

e.g. there is docker support to run convertes and frontends in parallel. See:

https://github.com/WolfgangFahl/nicescad/tree/main/docker

To make the different platforms cooperate we'd e.g. need a RESTFul way to "POST" designs into the blockscad editor and e.g. get back the openscad version of things as a response.

Is this project still alive enough to have any chance to get this done?

Icons for Blocks

Blocks should have icons to serve as visual hints. SVG appears to be Blockly's preferred format.

• Add icons to blocks

Rendering failure with variable assignment in block

I am trying to increment a variable based on a loop counter and hitting a rendering failure. This might be the same as issue #3, but I can't be certain. If that is the case, how should I perform this sort of variable modification for a loop? I was trying to create a stack of increasingly larger spheres on the y-axis.

OpenSCAD code view:

//!OpenSCAD

offset = 0;
for (radius = [1 : abs(2) : 10]) {
  offset = offset + radius;
  translate([0, radius, 0]){
    sphere(r=radius);
  }
}

<xml xmlns="http://www.w3.org/1999/xhtml"><block type="variables_set" id="688" x="28" y="7"><field name="VAR">offset</field><value name="VALUE"><block type="math_number" id="705"><field name="NUM">0</field></block></value><next><block type="controls_for" id="784"><field name="VAR">radius</field><value name="FROM"><block type="math_number" id="785"><field name="NUM">1</field></block></value><value name="TO"><block type="math_number" id="786"><field name="NUM">10</field></block></value><value name="BY"><block type="math_number" id="787"><field name="NUM">2</field></block></value><statement name="DO"><block type="variables_set" id="710"><field name="VAR">offset</field><value name="VALUE"><block type="math_arithmetic" id="727"><field name="OP">ADD</field><value name="A"><block type="variables_get" id="732"><field name="VAR">offset</field></block></value><value name="B"><block type="variables_get" id="794"><field name="VAR">radius</field></block></value></block></value><next><block type="translate" id="755"><value name="XVAL"><block type="math_number" id="756"><field name="NUM">0</field></block></value><value name="YVAL"><block type="variables_get" id="763"><field name="VAR">radius</field></block></value><value name="ZVAL"><block type="math_number" id="758"><field name="NUM">0</field></block></value><statement name="A"><block type="sphere" id="774"><value name="RAD"><block type="variables_get" id="801"><field name="VAR">radius</field></block></value></block></statement></block></next></block></statement></block></next></block></xml>

Support for enumeration of variables for drop-down menus like Customizer

In OpenSCAD, with the Customizer interface it's possible to instantiate drop-down menus using comments for the customizer:

//Part
PARTNO = "0"; // [0:All, 1:Top, 2:Bottom]

Add that as an option for variable assignment?

Unfortunately, adding comments to a variable doesn't quite have the same effect for use in OpenSCAD:

// [0:ball, 1:square, 2:dovetail]
endmillshape = "ball";
