How It Works

LuminiCAD converts your text descriptions into precise CAD models. Simply describe what you want to create, and we’ll help you build it.
Start with basic shapes and add details gradually. This helps ensure your description is interpreted accurately.

​
Basic Descriptions

Here are some examples of how to describe common shapes: 
"Create a cylinder 50mm in diameter and 100mm tall"
"Make a rectangular box 100mm wide, 50mm deep, and 75mm high"
"Draw a sphere with 30mm radius"

​
Adding Features

You can modify shapes by describing additional features: 
"Add a 10mm diameter hole through the center"
"Create 4 equally spaced holes of 6mm diameter"
"Make a rectangular cutout 20mm by 30mm"

​
Practical Examples

​
Example 1: A Simple Bracket

"Create an L-shaped bracket 100mm tall and 75mm wide, 
with a thickness of 8mm. Add 10mm mounting holes 
in each end, positioned 15mm from the edges"

​
Example 2: A Custom Container

"Make a cylindrical container 80mm in diameter and 120mm tall. 
Add a screw-top lid with 2mm thread pitch. Include 4 reinforcement 
ribs equally spaced around the outside"

​
Tips for Better Results

  1. Be Specific
    • Include measurements when possible
    • Specify orientations (vertical, horizontal)
    • Mention important relationships (“centered”, “aligned with”)
  2. Build Gradually
    • Start with the main shape
    • Add features one at a time
    • Review and adjust as needed
  3. Common Terms
    • “Centered” or “in the middle”
    • “Equally spaced” or “evenly distributed”
    • “Through all” for holes
    • “Symmetric” or “mirrored”

​
Advanced Features

​
Combining Shapes

"Combine a cylinder and a box, with the box centered 
on top of the cylinder. The cylinder should be 50mm 
diameter and 30mm tall, and the box should be 
40mm square and 20mm tall"

​
Complex Patterns

"Create a hexagonal pattern of 5mm holes, with 
15mm spacing between centers, covering an area 
of 100mm by 100mm"
If the result isn’t exactly what you wanted, try describing it in a different way or break it down into simpler steps.

​
Common Challenges

​
Ambiguous Descriptions

"Make it bigger"
"Add some holes"
"Put it on top"

​
Complex Geometry

For complex models, consider:
  1. Breaking down into simpler components
  2. Using the scripting interface for precise control
  3. Combining text commands with manual adjustments
Remember that you can always switch to the scripting interface for more precise control over your design.
Like any AI tool, LuminiCAD may sometimes misinterpret complex descriptions. For best results:
  • Break down complex shapes into smaller, simpler parts
  • Build your model step by step
  • Be specific with measurements and relationships
  • Review each step before moving to the next
The key to success is in how you describe your model. Think of it as a conversation: the clearer and more structured your description, the better the outcome.
