How to Put Dimensions in SolidWorks Drawings
Master dimensioning SolidWorks drawings with a step-by-step approach: setup, primary and driven dimensions, tolerances, multi-view consistency, and clean export for print or PDF.
This guide explains how to put dimensions in SolidWorks drawings, covering primary dimension placement, tolerances, driven dimensions, and multi-view consistency. You’ll learn to use Smart Dimension, define units, adjust alignment, and export clean PDFs. Prerequisites include a SolidWorks license with the Drawing module and a standardized template.
Understanding dimensions in SolidWorks drawings
According to What Dimensions, precise dimensioning is the foundation of reliable CAD communication. If you’re wondering how to put dimensions in SolidWorks drawing, this block explains the core concepts and the rationale behind dimension placement. Dimensions describe size, location, and tolerances for features, while keeping drawings readable. A well-dimensioned drawing minimizes ambiguity and reduces rework. Start by identifying critical features that define form and fit, then plan how many dimensions each view should carry. In practice, you’ll combine linear dimensions with diameter, radius, and angular annotations as appropriate, ensuring every measurement maps directly to a model feature. The What Dimensions team emphasizes consistency across the document, so unify units and notation to prevent confusion downstream. This foundation helps you build a robust, scalable drawing workflow that works for engineers, designers, and manufacturing teams.
Tools & Materials
- SolidWorks software (with Drawing module)(Ensure the module is enabled for drawing features)
- Computer with adequate specs(Fast enough for Smooth Dimensioning sessions)
- Mouse or drawing tablet(Precise clicking and tapping for placement)
- Printer or PDF exporter(For final deliverables and reviews)
- Unit setup reference (mm or inches)(Set consistent units before dimensioning)
Steps
Estimated time: 60-90 minutes
- 1
Open drawing and verify template
Launch your SolidWorks drawing, select the standard template, and confirm the units, scale, and font. This baseline ensures consistency as you add dimensions. If the template includes a GD&T block, decide early whether to populate it now or later.
Tip: Use a template with predefined dimension styles to save time. - 2
Configure advanced options
In the Options menu, set standard dimensioning preferences (arrow style, text height, leaders) and ensure view alignment rules are consistent across the document. This reduces rework when adding dimensions in later steps.
Tip: Document-wide consistency saves hours of edits later. - 3
Activate Smart Dimension
Choose Smart Dimension from the Sketch toolbar or right-click and select it. Hover over a feature edge or center, then click to create a dimension. Drag to position the dimension line and release to finalize.
Tip: Use auto-positioning to minimize overlapping leaders. - 4
Place primary dimensions on key features
Place essential dimensions on the primary views (front, top, side) to establish design intent. Prefer one dimension per feature and avoid crowding. Use diameters for holes and radii for fillets where appropriate.
Tip: Prioritize readability over completeness in crowded views. - 5
Add chained vs. individual dimensions
Use chained dimensions only when the geometry implies a single measurement. Otherwise, place each dimension with its own leader to improve clarity and reduce misinterpretation.
Tip: When in doubt, split chained measurements into separate dimensions. - 6
Link dimensions to datums and notes
Attach dimensions to datum references for critical features. If you’re using GD&T, include feature control frames and datum references to communicate manufacturing intent.
Tip: Datum references anchor measurements to real-world features. - 7
Incorporate driven dimensions and relations
Create driven dimensions by linking a drawing dimension to a model parameter or equation. Apply relations (equal, parallel, perpendicular) to maintain logical consistency across features.
Tip: Driven dimensions update automatically when the model changes. - 8
Check cross-view consistency
Ensure dimensions align between views, using projection lines to connect related features. Verify that tolerances, units, and note blocks are consistent across all views.
Tip: Cross-view checks prevent mismatched specifications. - 9
Review and finalize
Run through the drawing to verify accuracy, update any missing tolerances, and confirm that all dimensions reference the correct features. Prepare the drawing for export or print.
Tip: Use a final read-through to catch minor inconsistencies.
Quick Answers
What does the term 'driven dimension' mean in SolidWorks drawings?
A driven dimension is an annotation tied to a model parameter or equation rather than to the geometry itself. It updates automatically when the underlying design changes, helping keep drawings synchronized with the CAD model.
A driven dimension is a parameter-linked measurement that updates automatically as the design changes.
Can I show dimensions across multiple views in SolidWorks?
Yes. Place key dimensions in primary views and reference them in adjacent views using projection lines or shared dimensions. This maintains consistency and avoids duplicating measurements.
Yes, you can, by aligning and projecting dimensions between views to keep things consistent.
How do I change dimension precision or tolerances?
Select the dimension, open its properties, and adjust the decimal precision or tolerance type (bilateral, unilateral, limit). Apply changes and verify consistency across the drawing.
Change precision in the dimension properties and re-check all views for consistency.
Why are my dimensions not aligning between views?
Misalignment often results from inconsistent projection lines, different views using separate dimension styles, or misapplied datums. Reconcile by re-establishing shared references and applying a uniform style.
Misalignment usually comes from inconsistent references or styles; fix by standardizing references and styles.
Is it possible to export drawings with dimensions to PDF?
Yes. Use the Export or Print option to output a PDF with the selected scale and view settings. Verify that all dimensions are legible and not clipped in the PDF.
You can export dimensions to PDF; just ensure scale and view settings preserve readability.
