HiCAD Viewer 2021 is a specialized viewing tool designed to enable non-HiCAD users to assess complex 2D and 3D drawings without requiring a full software license. It offers a modern, ribbon-based interface and is particularly valued in industries like steel engineering, sheet metal, and plant design. Core Functionality
Multi-Format Support: Beyond native HiCAD files, it can display common image formats including TIFF, JPG, BMP, PNG, and GIF.
Assessment Tools: Users can perform 3D distance measurements and 2D element measurements directly within the viewer.
Visualization: It provides realistic representations of 3D models with various visualization modes, dynamic zoom, and rotation functions.
Inter-App Integration: Features drag-and-drop support, allowing users to pull drawing elements, parts, or assemblies into other applications like Microsoft Word or Paint. Key Improvements in the 2021 Version
The 2021 release introduced several performance-oriented updates from the ISD Group:
New Renderer: A major update shifted all modules to OpenGL version 4.3, significantly accelerating graphics output and providing higher frame rates for smoother zooming and rotating.
Active View Identification: The "active view" is now clearly highlighted with a colored, wider frame, making it easier to track which part of a complex drawing is being edited or inspected.
Enhanced View Management: Users can now create up to 9,998 sheet areas and views, a massive increase for large-scale projects.
Zoom to Detail: New functions allow users to automatically zoom to sectional or detailed views at the largest possible scale, with the sectional view becoming the new "active" view. Critical Considerations
Hardware Requirements: Due to the shift to OpenGL 4.3, HiCAD 2021 (including the viewer) no longer runs effectively on computers without a standalone graphics card. Onboard chips may lack the power for complex designs.
Learning Curve: While the G2 reviewer notes an intuitive interface, the extensive feature set can still be challenging for total beginners.
Platform Lock-in: As a proprietary viewer, its primary strength is handling the unique "all-in-one" 2D/3D data typical of the HiCAD ecosystem, which might be overkill for users only needing standard CAD file viewing.
Since "HICAD" is less common than standard AutoCAD, this post focuses on its niche use case (often related to Japanese CAD standards or older technical drawings). Key Features 1
1. Dual Platform Support (2D and 3D) Unlike many viewers that focus solely on 3D models, HiCAD Viewer retains robust 2D capabilities. It allows users to open 2D technical drawings alongside their 3D counterparts, which is essential for manufacturing teams who rely on dimensioned prints.
2. Cross-Native File Handling
One of the strongest selling points is its ability to handle native HiCAD files (.sat, .sar, etc.) without conversion. Additionally, it supports standard exchange formats like STEP, DXF, DWG, IGES, and VRML, making it useful for viewing data from other CAD systems, albeit with less feature intelligence than native files.
3. Analysis Tools The 2021 version includes decent analysis capabilities:
4. Integration with HELiOS For companies using ISD’s PDM system (HELiOS), the Viewer 2021 acts as a preview tool. This allows users to view documents directly from the PDM vault without checking them out or launching the full CAD software.
HiCAD Viewer 2021 is a free utility developed by ISD Software und Systeme GmbH. It allows users who do not own a full license of HiCAD to view, measure, and analyze 2D drawings and 3D models created in HiCAD.
It is an essential tool for collaboration, allowing engineers, project managers, and clients to review designs without the need for expensive CAD software licenses.
