Overview
nanoCAD
nanoCAD provides you with a high-performance CAD environment that feels instantly familiar if you have ever used traditional drafting software. You can create complex 2D drawings and 3D models using a native DWG format, ensuring your files remain compatible with partners and clients without data loss. The platform is designed to handle large-scale projects efficiently, offering a professional toolset for engineers, architects, and designers who require precision and reliability.
You can customize your workspace with an open API and specialized modules for mechanical design, construction, and topography. Whether you are drafting simple floor plans or developing intricate mechanical components, the software provides the speed and accuracy you need. It serves as a cost-effective alternative for teams of all sizes, from solo freelancers to large engineering firms, by offering flexible licensing options that fit your specific budget and project requirements.
PrusaSlicer
PrusaSlicer is a powerful, open-source tool designed to bridge the gap between your 3D models and your physical 3D printer. You can import STL, OBJ, or STEP files and transform them into G-code instructions that your machine understands. The software provides a clean, tiered interface that grows with your experience, offering Simple, Advanced, and Expert modes so you never feel overwhelmed by technical settings while maintaining full control over your prints.
You can optimize your print quality using built-in profiles for hundreds of different printers and filaments, saving you hours of manual calibration. Whether you are a hobbyist printing decorative figures or an engineer producing functional parts, the software helps you solve complex geometry challenges with features like automated wood-grain textures and smart cooling logic. It is completely free to use and works across Windows, macOS, and Linux systems.
Overview
nanoCAD Features
- Native DWG Support Open, edit, and save drawings in the industry-standard DWG format to ensure perfect compatibility with your clients and partners.
- Familiar User Interface Switch easily from other CAD systems with a classic ribbon or toolset interface that requires almost no retraining for experienced drafters.
- 3D Modeling Engine Create complex 3D geometries and surfaces using professional modeling tools that help you visualize your designs from every possible angle.
- Dynamic Blocks Save time by creating intelligent objects that you can adjust and manipulate visually without redrawing individual components from scratch.
- Open API Access Build your own custom commands and automate repetitive drafting tasks using C++, C#, or Python to speed up your unique workflow.
- Sheet Set Manager Control hundreds of drawings from a single panel to organize your project documentation and automate the printing of entire drawing sets.
PrusaSlicer Features
- Organic Supports. Generate tree-like structures that use less filament and break away easily without leaving marks on your finished 3D prints.
- Multi-Material Painting. Apply different colors or materials directly onto your 3D model with a virtual brush to create complex, multi-colored objects.
- Variable Layer Height. Smooth out curves by using thinner layers on detailed areas while speeding up vertical walls with thicker layers automatically.
- Measurement Tool. Verify the exact dimensions of your models and check clearances between parts before you commit to a long print job.
- Text Embossing. Add custom text, serial numbers, or logos directly onto your 3D geometry without needing to go back to CAD software.
- G-code Viewer. Inspect every individual layer and toolpath of your print before starting to identify potential issues and save expensive filament.
