Scale to Size - 2026 Pricing, Features, Reviews & Alternatives

Scale to Size is an add-in for Autodesk Fusion Three Hundred Sixty that enables CAD professionals to resize parametric and imported geometry to precise target dimensions without disrupting design intent. Developed by Nalagareng, the tool complements the native scale feature by allowing specific dimensional targets instead of unitless scaling factors. The solution caters to engineers, product designers, and digital manufacturers working in secure environments requiring local computation and privacy assurances. All operations occur within the Fusion environment, preserving design data on the local machine.

Scale to Size offers four core capabilities centered on dimensional accuracy and operational flexibility. The exact target dimension feature allows selection of an axis and entry of a final size in millimeters or inches while automatically calculating the scaling factor based on the bounding-box span. Proportional scaling maintains aspect ratio across all axes while single-axis scaling adjusts only the chosen dimension. Pivot behavior adapts to selection context by scaling each preselected body about its bounding-box center or by scaling the entire design around the world origin with optional auto grounding and horizontal recentering.

The dialog interface follows eight sequential steps that guide through body selection, unit toggle for millimeters or inches, proportional scaling toggle, grounding toggle, horizontal centering toggle, read-only dimension panel, axis selector, and target dimension input. Body selection supports multi-selection by shift-clicking and defaults to all bodies when no preselection is made. Parametric mode integration records scaling and relocation features in the timeline for subsequent editing while direct mode applies changes immediately with support for undo operations. For tasks involving extensive geometry, a progress dialog appears after a brief delay to provide feedback on computational processing.

Scale to Size operates exclusively through the Fusion Python application programming interface within the host process and does not open network connections, generate external log files, or collect telemetry. Installation is managed via bundled platform-specific installers for macOS and Windows and the add-in becomes accessible in the solid modeling workspace under the Modify menu once activated through the Add-Ins panel. Licensing and distribution occur through the Autodesk App Store under existing terms of service and privacy policies.
