Mastering SOLIDWORKS Exploded Views: A Step-by-Step Technical Guide

Creating an exploded view in SOLIDWORKS requires defining sequential spatial translation steps using the Exploded View PropertyManager to isolate assembly components along precise coordinate axes. By leveraging the 3D triad manipulator, radial explode algorithms, auto-spacing tools, and Smart Explode Lines, designers can generate parametric assembly graphics without modifying native mate relationships. Master these technical workflows to produce production-grade technical drawings, clear assembly documentation, and smooth exploded animations.

Assembly Preparation and Exploded View Technical Requirements

Before creating an exploded view in SOLIDWORKS, your assembly structure and spatial relationships must be validated. Exploded views do not break or override assembly mates, but an unorganized assembly tree or unresolved lightweight components can corrupt exploded configurations and cause route line disconnections.

Essential Pre-Operation Checklist

• Primary System & Hardware Setup: SOLIDWORKS Professional or Premium (2020 or newer recommended), dedicated workstation GPU with certified OpenGL drivers, mouse with a middle scroll button for rapid 3D triad orientation.
• Prerequisite Assembly Health Metrics: Fully defined core assembly mates (zero red/yellow mate errors), verified component suppression states, and all sub-assemblies set to Resolved mode (avoiding Lightweight or Quick View modes which restrict sub-assembly explode step editing).
• Target Output Standards: Clear target specification (e.g., ASME Y14.5M drawing views, digital service manual graphics, dynamic dynamic AVI/MP4 render animations).
• Workflow Budget Benchmark: 15–30 minutes for standard 50-component mechanical assemblies; 45–90 minutes for complex 500+ component multi-level assemblies requiring custom routing lines and sub-assembly step propagation.

Step-by-Step Workflow for Creating Exploded Views in SOLIDWORKS Assemblies

Step 1: Initialize the Exploded View PropertyManager

1. Open your fully assembled model in SOLIDWORKS.
2. Navigate to the Assembly tab on the CommandManager.
3. Click Exploded View (or select Insert > Exploded View from the top pull-down menu).
4. Verify that the Exploded View PropertyManager opens on the left panel. SOLIDWORKS automatically creates a new exploded view instance tied to the active configuration inside the ConfigurationManager.

Pro-Tip: Always create a dedicated assembly configuration (e.g., "Config_Exploded_Production") in the ConfigurationManager before creating complex exploded views. This isolates graphic variations and prevents unintended layout changes in your primary design configuration.

Step 2: Define Component Selection and Triad Vector Translation

1. In the graphics area, left-click the component (or group of components) you wish to isolate first. Selected components highlight in blue and appear under the Exploded View Components selection box.
2. A 3D manipulator known as the Triad appears on the selected geometry. Left-click and hold one of the triad’s directional axes (X, Y, or Z arrowheads) to define the translate direction.
3. Drag the cursor to move the component along the chosen axis.
4. Fine-tune the precise linear distance in the PropertyManager under Explode Step Distance (e.g., enter 150.00mm or 6.00in).
5. Click Done at the bottom of the Explode Step section to finalize Explode Step1.

Warning: Do not click the green checkmark at the top of the PropertyManager until all individual explode steps are complete. Clicking the green checkmark exits the tool, requiring you to right-click the Exploded View feature in the ConfigurationManager to edit and add subsequent steps.

Step 3: Implement Radial Explodes and Auto-Spacing Algorithms

For circular bolt patterns, concentric fasteners, or radial housings, linear manual dragging is inefficient. Use automated array translations:

1. Select all hardware items surrounding a central axis (e.g., 8 M8 hex bolts on a flange).
2. Change the explode type from Regular Step to Radial Step near the top of the PropertyManager.
3. Select a cylindrical face or linear axis to serve as the radial center direction.
4. Drag the radial triad ring outward; SOLIDWORKS will move all 8 fasteners outward symmetrically along their respective radial vectors.
5. To automatically space stacked components (such as a bolt, washer, lock washer, and nut):
   
   
   • Select the stacked components sequentially.
   • Under Options, check Auto-space components on drag.
   • Drag the primary direction arrow. Adjust the Distance between components slider to establish uniform physical gaps between every element in the stack.

Step 4: Manage Sub-Assembly Exploded States and Hierarchy Depth

By default, SOLIDWORKS treats top-level sub-assemblies as rigid single objects. To explode internal sub-assembly parts within the top-level model:

1. Select the sub-assembly in the graphics area or FeatureManager design tree.
2. In the PropertyManager, scroll down to Explode Strategy.
3. Toggle between Explode Sub-Assembly Components and Rigid Sub-Assembly.
4. Alternatively, if the sub-assembly already contains an internal exploded view defined at its own part level, click Reuse Sub-Assembly Exploded View to automatically inherit its internal step sequence.

Step 5: Construct Parametric Smart Explode Lines (Route Lines)

Clear technical documentation requires path lines showing how parts fit together.

1. Exit the main Exploded View interface by clicking the green checkmark.
2. In the Assembly CommandManager, click the dropdown below Exploded View and select Explode Line Sketch (or click Smart Explode Lines).
3. Under the Smart Explode Lines PropertyManager, click Update. SOLIDWORKS automatically generates 3D sketch lines connecting fastener heads to hole centers and component centroids along explode paths.
4. To alter individual paths, manual 3D route lines can be modified by selecting line segments, adding jog lines, or altering connection endpoints directly on component surfaces or vertices.

Step 6: Audit, Edit, and Re-order Explode Steps

1. Switch to the ConfigurationManager tab on the left sidebar.
2. Expand the active configuration, then expand Exploded View 1 (or your custom named exploded view).
3. Right-click Exploded View 1 and select Edit Feature.
4. In the Explode Steps list, drag steps up or down to re-order the assembly/disassembly sequence.
5. Right-click any individual step (e.g., Explode Step 3) and select Edit Step to revise distances, change direction vectors, or modify component selection sets.
6. Right-click the assembly in the graphics area and select Animate Explode or Animate Collapse to run a real-time motion preview of the sequence.

Technical Comparison of SOLIDWORKS Explode Methods and Features

Troubleshooting Assembly Exploded View Conflicts and Display Failures

Scenario 1: Sub-assemblies Moving as Rigid Bodies Instead of Exploding Individually

• Root Cause: SOLIDWORKS treats sub-assemblies as single rigid units by default in top-level assemblies to conserve graphical processing memory.
• Actionable Fix: Edit the top-level Exploded View feature. Select the sub-assembly step, scroll down to the Sub-Assembly Explode Step panel, and select Explode Sub-Assembly Components. Alternatively, set the sub-assembly solve state to Flexible within the component properties dialog.

Scenario 2: Exploded Route Lines Crossing Geometry or Disconnecting After Component Revisions

• Root Cause: Component geometry references changed, or non-orthogonal linear movement caused 3D sketch paths to calculate skewed routes through solid bodies.
• Actionable Fix: Delete the broken 3D route sketch segment. Open Explode Line Sketch, select Jog Line, and insert manual jog points to route lines clear of solid faces. If geometry was modified, select the Smart Explode Lines PropertyManager and click Re-calculate All Lines.

Scenario 3: Exploded View Fails to Appear in 2D Technical Drawing Views

• Root Cause: The drawing view reference properties are pointing to the standard collapsed model configuration, or the "Show in exploded state" flag is disabled.
• Actionable Fix: Click the drawing view border on your 2D sheet to open the Drawing View PropertyManager. Under Reference Configuration, select the specific configuration containing the exploded view. Check the box labeled Show in exploded or model break state. If multiple exploded views exist, select the desired exploded view name from the dropdown menu.

Scenario 4: Triad Direction Misaligned with Required Translation Vector

• Root Cause: The component was created off-axis relative to the global assembly coordinate system, causing the triad to default to an inconvenient angle.
• Actionable Fix: Right-click the triad center sphere, select Align To, and pick a linear edge, planar face, or reference axis on the model. Alternatively, hold the Alt key, click the triad center point, drag it onto any cylindrical or planar reference face to instantaneously align the translation vector to that face's normal direction.

Frequently Asked Questions

How do I save an animation of an exploded view in SOLIDWORKS?

Right-click the assembly name or the Exploded View feature in the ConfigurationManager and select Animate Explode. In the Animation Controller pop-up toolbar, click the Save Animation icon (floppy disk), select your target video format (e.g., .avi or .mp4), set your frame rate (30 fps recommended), and click Save to render.

Can I copy an exploded view from one configuration to another?

Yes. In the ConfigurationManager, locate the source Exploded View item. Click and hold the Exploded View feature, then drag and drop it directly onto the target configuration name. SOLIDWORKS replicates all steps, translation distances, and route lines into the new configuration.

How do I temporarily collapse an exploded view without deleting the steps?

Double-click the Exploded View feature in the ConfigurationManager, or right-click anywhere in the graphics viewport and select Collapse. You can toggle between exploded and collapsed states at any time by double-clicking the feature or using the right-click context menu.

Why are my explode route lines missing when I export to PDF?

Sketch visibility settings often hide 3D sketches during export. Ensure that View > Hide/Show > Routing Sketches and View > Hide/Show > Sketches are enabled in the main menu before exporting your drawing or assembly to PDF format.
