IIACAD is a switch made easy for any CAD user

Much more than a cost-effective alternative, IIACAD is making no compromises in features and innovations.

IIACAD 2024 Features

Much more than a cost-effective alternative, IIACAD is making no compromises in features and innovations.

Experience the agility of IIACAD 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. IIACAD brings your productivity to the next level with smart productivity tools, beyond what you have experienced so far.

Smart Dimension

The SmartDimension command allows to create Dimensions by specifying entities. You can apply the command to Lines, PolyLine segments, Arcs, Circles, and Rings.

Drawing Compare

Compare two versions of a drawing to display the differences with colors. The new Drawing Compare palette allows you to compare the current drawing with another one. Eg. Understand modifications made by a colleague, compare two options for the same project, show before and after etc.

Data Extraction Wizard

Extract information from entities or blocks to a table or a CSV file. The Data Extraction Wizard enables you to quickly create a bill of materials or 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.

Grip Editing – Hatch | Gradient

Manipulate the contour of your hatch or gradient hatch like if it was a Polyline. Select any hatch entity and you will see grips to help manipulate directly the shape. Hovering over a grip point displays also a contextual menu with editing options.

Associative Patterns

Array copies of the same entity along multiple lines and columns and modify the pattern as you wish. Patterns allow you to replicate an entity following a linear or circular organization or along a path. These patterns are now associative. You can now edit them using grips or by a double-click on the associative pattern.

PCX Print Configuration Files

Equivalent to the PC3 format in other CAD software. Import PC3 files or create and save new printer configuration files in PCX format. It makes it easy to reuse and share with colleagues the same configuration for successive printings. Available for Windows only.

Work Faster in 3D

New OFFSETEDGES and CONVERTEDGES commands. These new 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.

Customize Your Workspaces

New CAD General workspace. The CAD General workspace offers an alternative ribbon to the default “Drafting & Annotation” workspace of IIACAD. Icons are reorganized to facilitate the switch from AutoCAD® or other similar CAD software. Easily create and save your workspaces Reorganize the user interface of IIACAD as you wish and save your configuration as a new workspace. Available for Windows only.

PDF Import

The ImportPDF command lets you insert content from Adobe® PDF files as Blocks into your drawings. You can insert all or selected pages from multiple page PDF documents. If the PDF file contains vectors, they are converted to drawing entities such as lines, circles, ellipses, and splines. Raster graphics in a PDF file are stored as image files on the hard disk which are then referenced as images in the drawing where you import the PDF file. Available for Windows only.

Lasso Selection

New selection method to save time. Use the lasso selection method to specify entities within an irregularly formed contour specified by dragging the cursor.

Power Trim

Trim or extend entities faster than with any other CAD Software. Trim multiple entities in once by moving your mouse around. Just describe a path with your mouse and IIACAD will trim while you move. If you use the shift key you do the same but with the Extend command.

Mouse Gesture

You can use a mouse gesture as a shortcut to execute a command, similar to a keyboard shortcut. Once you learn command mappings, you can use mouse gestures to invoke mapped commands quickly. The GESTURE command lets you customize up to eight gesture commands.

Save in DWG 2018 format

IIACAD is using the DWG format as its native format which makes it easy to share files with other CAD software such as AutoCAD® or MicroStation®. You also keep the ability to save in previous versions of the DWG format. Other drawings formats supported include DXF, DWF, DWT, DWS or DGN (import).

Heads up Display

The Heads-up Display toolbar that appears when you select entities in the graphics area. Using Heads-up Display, you can quickly zoom to the specified entities, change the entities Layer, Line Style, and Line Weight, Dimension entities, or create Blocks from the selected Entities.


The VoiceNote command lets you record audio notes and embed them in drawings. To record your voice as a VoiceNote, either add or retrieve an existing VoiceNote icon after issuing the VoiceNote command. This will open the dialog box. In the VoiceNote dialog box are four audio controls: record, play, pause and stop.

BIM Features

(Available for Windows only)

BIM Navigator

Import IFC and RVT files and filter out only the BIM information you need The BIM Navigator palette enables you to import and view one or multiple BIM files in IIACAD. 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 Properties

Select objects and read their BIM properties 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.

BIM Data Extraction

Export the properties of selected BIM objects into tables in the drawing or CSV files for spreadsheets Select BIM entities manually, or from the filters in the BIM Navigator, and extract their BIM data. The wizard helps you isolate only the properties you need. The data can be inserted as a table in the drawing or exported to a CSV file for use in Excel or other programs.
