Free Professional 2D/3D CAD Software - MEDUSA4 Personal
MEDUSA4 Personal: The powerful, FREE 2D/3D CAD package for Windows and Linux
The free MEDUSA4 Personal CAD software is part of the MEDUSA4 family of CAD solutions. Its extensive design functionality, similar to the most advanced commercial package, includes basic 3D, parametrics, colour image integration and sheet metal design. The free download is available in English, German, French, Italian and Japanese. Sheets carry a "not for commercal use" watermark (which can be removed via the eSERVICES pay-per-result portal for commercial users).
CSG eSERVICES Portal: Unlock drawings for Commercial Use
Private, non-commercial use, and the deployment of the software for educational and research purposes is completely free of charge. Businesses do not have to pay for the software, only for commercially viable results. Companies wishing to use the software commercially can do so on a pay-per-result basis. The CSG eSERVICES portal unlocks MEDUSA4 Personal drawings for unlimited commercial use.
Private use of MEDUSA4 Personal is completely free. Use the powerful CAD package for product design, model engineering or DIY projects.
Use MEDUSA4 Personal free in businesses. Convert finished designs into DXF/PDF for a small fee for commercial use.
Students, schools, universities and public research institutions can use MEDUSA4 Personal free of charge. We can also arrange for free DXF/PDF conversion credits.
Below is a short descriptiption of some of the modules contained in MEDUSA4 Personal. For a quick overview comparing the software to our commercial packages, have a look at the MEDUSA4 Packages and Modules Overview (PDF).
Unlike other free or cheap CAD systems, MEDUSA4 Personal is a fully functional MCAD suite with extensive, intelligent 2D tools and drafting functionality, including dynamic line and geometry creation tools, construction lines, grids, text tools, hyperlinks, a structure tree for logically grouping geometry, layer management, flexible dimensioning, and the ability to change sheet units from metric to imperial.
MEDUSA4 Personal contains the free basic 3D add-on, which allows users to quickly create 3D models based on 2D drawings - also known as "sheet-based modelling". This simple method was developed for designers who want to take their existing knowledge into a 3D world, making it accessible even to people without 3D modelling knowledge. The software also provides an integrated 3D model viewer.
The PARAMETRICS (variational geometry) module included with MEDUSA4 Personal provides the functionality required to parameterise 2D drawings to quickly create design variants, and to automate many manual design, simulation and testing processes.
Sheet Metal Design
The Sheet Metal Design (SMD) module included with the free CAD package draws on MEDUSA4’s 2D drafting and 3D modelling capabilities. Starting in 2D or 3D, users can modify a flat pattern using the powerful tools provided, and then refold the model to ensure that the final solution is exactly what is required. Sheet metal features, such as flanges, tabs, corner tears and punching, can all be added in 2D, either explicitly, or as defaults. A powerful bend allowance tool allows you to correct your geometry or specify your own algorithm for bend allowance.
The DXF/DWG interface provided with MEDUSA4 Personal allows you to import and edit existing 2D drawings. If you need to create DXF files from your MEDUSA4 Personal .SHE sheets for commercial use, you can convert the sheets at the CSG eSERVICES portal for a small fee. Universities or other educational institutions entitled to use the software for free can request free conversion credits for their eSERVICES account.
SMART Drafting Tool
The free MEDUSA4 Personal CAD software includes a Smart Drafting Tool for quickly and easily creating geometry. It allows construction lines to be automatically inferred between points created, and displays them dynamically as the cursor moves inside the drawing area. Users can automatically snap to existing segment points, determine grid step length and angles for subsequent points, determine incremental angles relative to the last line and easily extend existing geometry. Context sensitive information fields dynamically display segment length, angle or radii information as users draw their geometry.
MEDUSA4 Personal includes a SMART Edit tool for dynamically editing designs, also known as "parametrics on demand." The tool allows you to edit any drawing directly by selecting and dragging lines, or entering precise values for sizes and positions of geometric elements to effect change dynamically. Alternatively, drag or edit existing dimensions to create the correct geometric changes. SMART Edit deduces your intent from the geometry as a whole, taking into consideration dependent relationships between elements, and giving users a visual pointer as to how a change will affect their geometry.
Customisable Tool Trays
MEDUSA4 Personal allows users to customise their tool trays for simple or more complex requirements, by selecting a basic or complete set of tools from the View>Set of tooltrays option. The complete set contains all the available tools in MEDUSA4 Personal, while the basic contains all the basic tools for creating geometry and text, and provides an ideal starting point for new users.
Text Translation Tool
The text translation tool provided with MEDUSA4 Personal (available via the book icon on the complete "Text + Dimension" tool tray) can translate on-sheet texts word by word or phrase by phrase from and to English, French, German and Italian, by consulting a database of standard MCAD terminology provided. Users can edit or create their own translation databases.
Parts Numbers and Parts Lists
The free MEDUSA4 Personal 2D/3D CAD program allows users to add attributes to elements on a sheet, including parts numbers, item number balloons and user defined attributes. These can then be included in automatically generated parts lists, which can be positioned on the drawing or exported.
Save Money and Gain Flexibility with Professional CAD Software
MEDUSA4 Personal is a free professional CAD system for Linux and Windows, equal to all design engineering challenges. The commercial version is used by well-known companies throughout the world because of its flexibility when it comes to design automation, standards compliance, systems integration and customisability. Private users and small businesses can reap most of these benefits free of charge. Those wishing to use designs commercially have no upfront software costs, only paying a small fee to convert finished designs used for economic gain.
