My pretty Computer-Aided Design🌺

Hey there!✨ So, I'm about to dive into modeling a 3D box that will be printed using PET filament in CATIA. It's my first time doing this, and I'm super excited! I'll be using CATIA to design and visualize every detail of the front and back of my sketched showsack, ensuring it's perfect for printing. Let's get started!

By following this approach, we'll have a sleek and functional mechanism where the acrylic wall and 3D printed component work together to create a secure housing for the battery and servos. Let's get creative! 🚀

How to get started bae

Hollow Box Design: We'll design a hollow box structure with two main parts:
- Part 1: A wall made of acrylic, which will be in contact with the back.
- Part 2: Printed in 3D, this part will contain the battery and the four servos.
Acrylic Wall (Part 1): This part will serve as the back wall of our box. It will provide stability and support to the entire structure.
3D Printed Component (Part 2): This part will be custom-designed to fit the battery and four servos snugly. It will ensure that everything stays in place securely.

Sandwich Assembly: We'll assemble the components in a sandwich-like manner:

Place Part 1 (acrylic wall) against the back.
Insert Part 2 (3D printed component) into the hollow space created by Part 1.

This assembly will create a sturdy structure where the battery and servos are safely housed.

My process in a 🩰nutshell🩰

File -> New -> Part: Open a new part document in CATIA.
Xy horizontal: Start your sketch on the XY plane for printing from bottom to top.

Sketch: Time to sketch! Create a new sketch on the XY plane.

Centered rectangle: Use the centered rectangle tool to draw the base of your box.

Constraint (Smart Dimension): Apply a smart dimension of 150 mm for length and 160 mm for width, so the acrylic sticks out a bit.

Trim: Clean up your sketch by trimming away any extra lines.

Mirror: Mirror your sketch to complete the base of the box.
Exit Workbench: Get out of sketch mode.
Pad: Time to pad! Extrude your sketch to create the base of the box with a thickness of 3 mm.

Edge Fillet: Round off the edges with a 9 mm fillet for a sleek finish.

Material (Acrylic): Apply the acrylic material to your box for that authentic look.

Shading: Adjust the shading settings to make your box look super realistic.
Clip (Hole): Create a hole for the screw, making it 1.5 times the diameter of the screw for a perfect fit. And follow the previous steps to make the front part.

My weekly cheat sheet

So i´m gonna describe you the tools that I used for this practice in Catia girl, don´t freak out, you got this!

Part Design Workbench: This workbench allows you to create and modify 3D solid models. You'll use features like Pad (for extrusions) and Hole (for creating holes) to design the box.
Sketcher: Sketcher is where you'll create 2D profiles that will later be extruded to form the box and holes. You can define dimensions and constraints using intelligent constraints and dimensions.
Extrude: The Extrude feature allows you to extend 2D sketches into the third dimension to create solid objects. You can specify the depth or distance of the extrusion using measurements or references.
Hole: The Hole feature enables you to create holes of various shapes and sizes on surfaces or solid bodies. You can define the position, diameter, and other parameters of the holes.
Smart Dimension: Smart Dimension is a tool that allows you to add dimensions to sketches and features. With Smart Dimension, you can easily specify precise measurements for the size and position of the box and holes.
