Browser-local CAD helpers for units, tolerances, fits, hole callouts, sheet metal, STL preparation, drawings, BOMs, and manufacturing readiness.
Use ScholarTool CAD tools to check model scale, estimate tolerance stack-ups, review fit clearances, draft hole and thread callouts, calculate sheet-metal bend allowance, prepare STL handoff checklists, generate drawing title blocks, build BOM templates, review engineering drawings, and organize manufacturing readiness notes without uploading CAD files or running CAD software.
This launch includes 10 CAD helpers across scale checks, tolerances, fits, callouts, sheet metal, STL preparation, drawing documentation, BOMs, and manufacturing release checks.
Use these helpers before exchanging geometry, quoting, printing, or handing CAD data to another workflow.
Use these helpers to structure preliminary tolerance, clearance, and hole-note decisions before formal drawing release.
Use the bend helper to estimate bend allowance, setback, deduction, and flat length before checking shop-specific bend tables.
Use these generators and checklists to organize title blocks, BOMs, drawing reviews, and release-readiness reviews.
CAD dimensions, tolerance values, checklist choices, and generated template text stay in the active browser page state. ScholarTool does not upload CAD files, store CAD model data, add analytics, or call third-party CAD APIs for these helpers.
These tools do not run CAD software, mesh engines, geometry kernels, STL parsers, STEP translators, OpenCascade, CAD viewers, CAM post-processors, solvers, or AI services. They are deterministic engineering helpers for review and documentation.
Compare source, target, expected, and detected dimensions to flag CAD unit-scale mismatch risk.
Generate a practical STL preparation checklist for 3D printing, simulation handoff, and quotation review.
Generate a drawing review checklist for dimensions, tolerances, notes, revisions, and manufacturing readiness.
Generate a manufacturing-readiness checklist for CAD models, drawings, BOMs, tolerances, and supplier handoff.
Calculate worst-case and RSS tolerance stack-up with target pass/fail guidance.
Calculate minimum and maximum clearance or interference between a hole and shaft.
Calculate bend allowance, bend deduction, setback, and flat length guidance.
Generate structured hole, thread, counterbore, and countersink callout text for review.
Generate a clean engineering drawing title-block text and table template.
Generate a bill of materials template for assemblies, drawings, prototypes, and manufacturing handoff.
ScholarTool category pages prioritize calculation context, unit discipline, assumptions, and interpretation so users can understand when a result is appropriate and when validated software or standards are required.
