SolidView

SolidView is a Python package that provides seamless 3D visualization of objects created with SolidPython2 in Jupyter notebooks. It leverages OpenSCAD for rendering and JupyterSCAD for interactive visualization.

Features

• 🎯 Easy Integration: Simple API for viewing SolidPython2 objects
• 🖥️ Cross-Platform: Automatic OpenSCAD detection on Windows, macOS, and Linux
• 📱 Interactive Viewing: Powered by JupyterSCAD for smooth 3D interaction
• 💾 STL Export: Built-in functionality to save objects as STL files
• 🧹 Smart Cleanup: Automatic temporary file management
• 🎨 Customizable: Configurable viewer dimensions and rendering options

Installation

Prerequisites

1. OpenSCAD: Download and install from https://openscad.org/
2. Python 3.8+: Make sure you have Python 3.8 or higher installed

Install SolidView

pip install solidview

Or install from source:

git clone https://github.com/mr-kam/solidview.git
cd solidview
pip install -e .

Development Installation

For development, install with additional dependencies:

pip install -e ".[dev]"

Quick Start

Basic Usage

from solid2 import *
from solidview import view3d

# Create a simple object
cube_obj = cube([10, 10, 10])
sphere_obj = sphere(8)
combined = cube_obj + translate([15, 0, 0])(sphere_obj)

# View it in Jupyter
view3d(combined)

Using the SolidViewer Class

For more control and better performance with multiple objects:

from solidview import SolidViewer
from solid2 import *

# Create a viewer instance
viewer = SolidViewer()

# Create and view multiple objects
for i in range(3):
    obj = translate([i * 20, 0, 0])(cube([10, 10, 10]))
    viewer.view(obj, width=800, height=600)

# Save an object as STL
viewer.save_stl(combined, "my_object.stl")

Custom OpenSCAD Path

If OpenSCAD is installed in a custom location:

from solidview import SolidViewer

viewer = SolidViewer(openscad_exec="/path/to/your/openscad")
viewer.view(your_object)

API Reference

view3d(obj, width=600, height=600, openscad_exec=None)

Convenience function for quick 3D visualization.

Parameters:

• obj: SolidPython2 object to render
• width (int): Viewer width in pixels (default: 600)
• height (int): Viewer height in pixels (default: 600)
• openscad_exec (str, optional): Path to OpenSCAD executable

Returns: JupyterSCAD viewer widget

SolidViewer Class

__init__(openscad_exec=None)

Initialize a SolidViewer instance.

Parameters:

• openscad_exec (str, optional): Path to OpenSCAD executable

view(obj, width=600, height=600, cleanup=True)

Render and display a 3D object.

Parameters:

• obj: SolidPython2 object to render
• width (int): Viewer width in pixels
• height (int): Viewer height in pixels
• cleanup (bool): Whether to clean up temporary files

Returns: JupyterSCAD viewer widget

save_stl(obj, output_path, overwrite=False)

Render an object and save as STL file.

Parameters:

• obj: SolidPython2 object to render
• output_path (str): Path for output STL file
• overwrite (bool): Whether to overwrite existing files

Returns: Path to saved STL file

Examples

Complex Object with Multiple Operations

from solid2 import *
from solidview import view3d

# Create a complex object
base = cube([30, 30, 5])
post = translate([15, 15, 5])(cylinder(r=3, h=20))
hole = translate([15, 15, -1])(cylinder(r=1, h=27))

final_object = base + post - hole

# View with custom dimensions
view3d(final_object, width=800, height=600)

Batch Processing

from solidview import SolidViewer
from solid2 import *

viewer = SolidViewer()

objects = []
for i in range(5):
    obj = translate([i * 15, 0, 0])(
        rotate([0, 0, i * 45])(
            cube([10, 5, 8])
        )
    )
    objects.append(obj)
  
# View each object
for i, obj in enumerate(objects):
    print(f"Object {i+1}:")
    viewer.view(obj)
  
    # Optionally save each one
    viewer.save_stl(obj, f"object_{i+1}.stl")

Troubleshooting

OpenSCAD Not Found

If you get an error about OpenSCAD not being found:

1. Check Installation: Make sure OpenSCAD is properly installed
2. Path Issues: On Windows, ensure OpenSCAD is in one of these locations:
   • C:\\Program Files\\OpenSCAD\\openscad.exe
   • C:\\Program Files (x86)\\OpenSCAD\\openscad.exe
3. Manual Path: Specify the path manually:

   viewer = SolidViewer(openscad_exec="C:\\path\\to\\openscad.exe")

Import Errors

If you encounter import errors:

pip install solidpython2 jupyterscad

Rendering Issues

• Memory: Large objects may require more memory
• Complexity: Highly complex objects may take longer to render
• Temporary Files: If cleanup fails, manually delete temp files in your system's temp directory
