The n°1 CAD alternative in DWG, trusted by industry leaders and millions of users

Available for Windows, macOS and Linux
Native DWG application
Create & Modify drawings in 2D and 3D

A Professional Cross-Platform CAD based on DWG

Designed to take your drawings Anywhere

Experience the agility of ARES Commander to create and modify DWG drawings in 2D and 3D on your computers. Leverage the drafting and design features that you’ve come to expect for your DWG files, at a significant cost savings.
ARES Commander brings your productivity to the next level with smart productivity tools and a unique concept: The Trinity of CAD™

Some of the main features:

Compare DWG documents

The new Drawing Compare palette allows you to compare the current drawing with another one. E.g., Understand modifications made by a colleague, compare two options for the same project, show before and after, etc.
Edit Hatches and Gradients Faster and Very Intuitively
Select any hatch entity and you will see grips that will help you to manipulate directly the shape. Hovering over a grip point displays also a contextual menu with editing options.

Push and Pull 2D and Faces into 3D Solids

With Push and Pull you can select the face of a 3D solid or 2D entities and extrude or subtract them in 3D. You can edit 3D solids by pushing or pulling faces. Push and Pull will also extrude closed areas like a rectangle, closed polyline or circle into a 3D solid and subtract any enclosed area. Alternatively, you can Push and Pull only selected entities. Arcs or Splines are converted into meshed surfaces.

Custom Blocks

The Custom Block Editor is launched with the command _EDITCUSTOMBLOCK or after a double-click on a block. You can use it to modify any block reference and also make them parametric in size and shape.
The contextual ribbon includes features to combine special grips and actions such as Move, Scale, Stretch, Rotate, Pattern, or Mirror. You may, for example, create a custom block whose size can be dynamically adjusted with a grip you can stretch.

Export BIM data to tables and Excel

The Data Extraction wizard enables you to quickly create a bill of materials or to extract other types of information from your drawings.


Select entities and filter only the data you want to extract. You can further insert it as a table in the drawing or generate a file that can be imported in a spreadsheet.

Import & filter IFC and Revit files in your DWG file

The BIM Navigator palette enables you to import and view one or multiple BIM files in ARES Commander. Supported formats include IFC (versions 2X3, 4 and 4×2), as well as RVT (Revit versions 2011 through 2020).
You can further use the filters to show/hide only the objects you need, combining criteria such as the discipline, category, floor, class, or other BIM properties.

Read BIM objects properties

Select objects and read their BIM properties with ARES Commander. While viewing and rotating the BIM project you can select objects. The BIM Navigator will highlight them in the Elements tree and the Properties Palette will display their BIM properties. Alternatively, you may select the objects from the elements tree and they will be highlighted in the project.

Speed up 3D Solid Modeling

The new Offset Edges and Convert Edges commands help you to extract 2D entities from the edges of 3D solids or surfaces. This is in particular useful to extract construction entities you will use as a reference to create other 3D shapes combining with boolean operations or Push/pull actions

Insert Satellite Images or Street Maps in Your DWG Drawings

Get free maps service for ARES Commander subscribers. Search for any address and get street maps and satellite images to insert in the background of your drawings. This professional map service is developed in collaboration with Esri, the world leader for GIS solutions. Maps are geo-referenced and offer different levels of details depending on the zoom factor. You can draw on top of these base maps or use the enquiry tools to collect the coordinates of a specific point, the area of a specific selection or the distance between two points. This plugin requires Internet service and is free with a valid ARES subscription.

3D real-time Rendering

The ARES Render Plugin is a WYSIWYG (What You See Is What You Get) real-time rendering technology. Its GPU-based raytracing render engine utilizes NVIDIA’s CUDA Technology to quickly visualize presentation-ready images of your 3D projects. It simulates realistic material behavior and reflections in real-time, under different lighting situations.


+ Physical Real-Time Rendering
+ Scientifically Accurate Materials
+ Simplified and very interactive
+ Easy Lighting
+ High-Quality Image Input
