We cooperate with local developers to provide industrial solutions for customers.

SDBOX is an additional software (Add-on) for GstarCAD and provides a great number of tools that help the processing and management of the design and drafting workflows of projects. SDBOX supports GstarCAD from version 2021.

SDBOX is an application running on GstarCAD offering a range of easy-to-use tools for Survey mapping and AEC. It includes all the tools needed for complete studies such as drawing templates, documentation tools, area and volume reports, setting-out, measurements and quotations, etc. This software is suitable for all kind of engineering development projects and includes detailed guides, step-by-step videos and instructions.
