A complete production environment for professional CAD work.
SDBOX is a professional CAD add-on built around real surveying and engineering deliverables. It brings source data, calculations, drawing standards, mapping resources, terrain processing and plotting into organized workflows inside AutoCAD-compatible platforms. Instead of moving between disconnected applications or repeating setup from scratch, users can progress from initial data to checked, print-ready output while every generated element remains a standard, editable CAD object.
Users can adopt only the workflow they need first and expand gradually, without changing the CAD environment, file format or drawing practices they already use.
Key features
The main SDBOX workflows are organized around the deliverables professionals actually produce every day: survey plans, terrain models, set-out drawings, spatial data exchange, building documentation and print-ready CAD output.
Survey drawings, property plans, symbols, boundaries, tables, legends, statements, declarations, title blocks and final output.
Point import, coordinate tables, calculations, operations, editor and draw by codes.
Triangulation, breaklines, contours, longitudinal profiles, cross sections and cut & fill calculations.
Coordinate documentation, axis geometry, labels, check and reference points and field deliverables.
KML, KMZ, SHP, DXF, JSON/GeoJSON and GeoTIFF workflows.
Online map backgrounds, georeferenced images, orthophotos and spatial data integration.
Floor plans, sections, elevations and as-built technical drawings.
Texts, symbols, blocks, dimensions, hatches, layers, annotations and drawing cleanup.
One-click PDF output, plotting tools, pre-set CTB pen tables for all scales and technical deliverables.
Area and length calculations, arithmetic with text and block values, geometry analysis, counting, data extraction and batch drawing operations.
Where SDBOX is used
How SDBOX fits into the drawing process
SDBOX can enter the process at different points. A project may start from survey points, an existing CAD drawing, a map background, a geospatial file, a raster reference or third-party design data.
Start from a CAD drawing, survey point file, map background, geospatial file, image reference or existing project data.
Use the relevant SDBOX workflow: survey drafting, DTM, contours, profiles, sections, maps, set-out, building survey or CAD production support.
Review, check and edit generated objects directly inside the CAD drawing.
Complete the drawing with scale-aware texts, symbols, dimensions, hatches, tables, legends, notes and title blocks.
Plot, export or deliver the final result as a print-ready drawing, PDF or exchange file.
Start with the workflow you need first
SDBOX can be adopted gradually. Users often start with one practical workflow — such as survey plans, map backgrounds, terrain modeling, set-out documentation or print-ready PDF output — and then expand when needed. The final result remains a normal CAD drawing, so teams can continue editing, checking, plotting and exchanging files with their standard CAD tools and habits.
Complete topographic and property plan drafting
SDBOX supports complete topographic and property plan drafting from survey point import to final print-ready output. It includes tools for existing conditions, building identification, terrain and area hatches, cartographic symbols, annotations, elevation levels, reference grids, planning and regulatory lines, boundaries, property documentation, coordinate tables, ready-to-use title blocks, declarations, print layouts, coordinate export and chainage/stationing.
Digital terrain model, contours, profiles, sections and volumes
Terrain models can be created and edited directly inside the CAD drawing. A distinctive SDBOX capability is that elevation information can be read from ordinary 2D survey points, so users do not need to import or maintain a separate set of 3D point objects. The same points can therefore support accurate plan drafting as well as TIN generation, breaklines, triangle editing, contour calculation and preview drafting, contour smoothing, longitudinal profiles, cross sections on one or multiple terrains and cut & fill volume calculations. No separate 3D point import is required.
Online maps, georeferenced images and GIS/CAD exchange
SDBOX provides direct access to background maps, Google Earth workflows, coordinate conversion tools, SHP and JSON spatial data import/export, world-file and GeoTIFF image workflows, KML/KMZ import with folders, colors and labels, Google Street View integration and georeferenced image processing. It is useful both for surveying practice and for spatial checking, visualization and data exchange.
Set-out drawings with coordinates and axis geometry
SDBOX can prepare controlled set-out drawings from third-party CAD designs, existing survey plans and design geometry. The workflow includes existing marks and control points, set-out point preparation, coordinate documentation, checking dimensions, labels and print-ready documentation for site implementation and field verification.
Building survey floor plans, sections and elevations
SDBOX includes a complete workflow for drafting building survey and as-built floor plans quickly and consistently. Drawing elements such as texts, symbols, tags, dimensions, hatches, titles and notes are inserted with scale-aware sizing. Tools cover layer creation, single-level or multi-level plans, filters and LMAN setup, section/projection lines, stairs, arrows, architectural symbols, doors, windows, opening tags, levels, dimensions, legends and one-click PDF output.
Sections and elevations can be drafted directly from floor plans, with Xref-based workflows, split-screen drafting, level markers, height references, generated doors/windows, hatches, symbols, notes and dimensions.
Scale-aware CAD productivity tools
Although SDBOX is mainly presented as a surveying, terrain modeling and mapping add-on, it also includes a wide range of general CAD productivity tools for everyday drawing production. These tools are useful both inside SDBOX workflows and in technical drawings that are not strictly related to surveying.
Annotation types, usage indicators, notes, headings, editor, alignment and bulk text management.
Scale-aware dimensions, offsets, angles, azimuths, radii, centers, path lengths and editing tools.
Hatch patterns automatically scaled to plot scale, including terrain, textures, walls, floors and sections.
Drawing, editing, conversion, length handling, line legends and predefined line types.
Scale-aware symbols, numbering, attributes, counting, tabulation, xrefs and symbol legends.
A4–A0 layouts, project base info, short descriptions, declarations, notes and legends.
Layer isolation, visibility, object transfer, filters, colors, lineweights and layer legends.
Bulk modifications, filters, replacements, scale adjustments, cleanup and object editing.
Path updates, optimized insertion, true-dimension scaling, image labels and batch management.
High-quality plotting, CTB pen tables for all scales, PDF generation and DXF export.

Installation, disk space and uninstallation
SDBOX Trial is installed by running the SDBOX installer for the selected CAD platform. The main SDBOX program folder is selected by the user during installation and requires approximately 100 MB. SDBOX also creates and uses the required components folder C:\sdbox_Tools, which is always created on drive C: and requires approximately 3 GB of disk space.
At the end of the installation, Windows opens the SDBOX first-load DWG, which contains the first-loading instructions. If more than one CAD application or a DWG viewer is installed, Windows may open this drawing in the program currently associated with DWG files rather than in the CAD application for which SDBOX was installed. In that case, simply close that program, open the correct CAD application, type APPLOAD, and load C:\sdbox_Tools\_CADsdbox.lsp. After the first successful loading, SDBOX is available from the CAD ribbon and menus. In each drawing session, the user presses Load SDBOX and all SDBOX commands and functions become available. See the first-start FAQ for detailed instructions.
To uninstall SDBOX, first run the SDBOX uninstall command from inside the CAD application. Then uninstall SDBOX from Windows Apps / Installed Apps. If manual cleanup is required, the user can remove the main SDBOX program folder and C:\sdbox_Tools.
Installer package. SDBOX uses a custom digitally signed installer. During installation, it downloads the required SDBOX components from SDBOX servers, including ZIP packages and required executable components.
Internet access. Internet access is required during installation and updates. It is also required for online documentation, map-related workflows and external web resources requested by the user.
If the embedded player is unavailable, watch the video directly on YouTube.
Evaluate the complete product and keep full control of your drawings
The same SDBOX installation is used for trial and licensed operation. Users install the trial first; after purchase, the license is activated without requiring a different program installation or a second setup package.
The trial is not a reduced-feature demo. It provides the same SDBOX commands and workflow capabilities as the purchased software, so the evaluation reflects real production use.
If the trial expires and no purchase is made, everything already created remains in the drawing as normal CAD content. The drawing can still be opened, edited, continued, plotted and exchanged; only the SDBOX commands are no longer available.
SDBOX is currently sold as a one-time purchase. There is no annual subscription at present.
The purchased version is protected by a USB Token. SDBOX may be installed on as many computers as needed — at the office, at home or on a laptop — but one license operates on one computer at a time: the computer where the token is connected. The token can be inserted or removed while CAD remains open.
Includes the Basic CAD productivity tools plus complete survey plan drafting, digital terrain modeling, Google Earth and maps, georeferenced data and GIS/CAD exchange.
Includes everything in the Survey edition and adds building survey floor plans, sections and elevations, together with set-out preparation and field documentation tools.
For the best experience and full functionality, BricsCAD, GstarCAD and ZWCAD work best in recent full versions, while progeCAD is supported from version 2026 onward. A full CAD edition is required; Light or Standard editions are not intended for full SDBOX functionality.
