Exploring the Line Between Simulation and Design
When we talk about CAD (Computer Aided Design), most people immediately think of tools like AutoCAD, SolidWorks, or CATIA. But what about Capstone Software, widely used in mechanical and electrical engineering labs?
Is Capstone a CAD software?
The short answer is: Not exactly but it plays a CAD adjacent role.
What is Capstone Software?
Capstone is a data acquisition and analysis software developed by PASCO Scientific. It is primarily used in physics, engineering, and control systems labs for tasks like:
- Real time data logging
- Sensor integration
- Plotting graphs (force vs. time, voltage vs. current, etc.)
- Analyzing mechanical motion, electrical signals, and thermodynamics
You can interface Capstone with hardware like:
- Rotary sensors
- Force sensors
- Motion carts
- Voltage probes
- Accelerometers
It’s a powerful experimental and simulation tool, but does it fall under the CAD category? Let’s break it down.

Why Capstone Could Be Considered CAD?
- Visual Environment for System Building
Capstone allows users to design experimental setups virtually before physical implementation.
You can drag components, simulate signal flow, and visualize interactions much like building blocks in electrical CAD tools (like NI Multisim or Proteus). - Real Time Simulation and Data Visualization
Simulation is builtin in many advanced CAD programs (e.g., SolidWorks Motion, ANSYS). Capstone focuses exclusively on the analysis side of physical systems, offering graphing, modeling, and real time feedback similar to simulation modules in CAD. - Integration with Control System Design
Capstone can model mechanical and electrical system behaviors under real conditions, making it useful in the design feedback loop, especially for control engineers.
Why Capstone is Not a Traditional CAD Software
Despite its strengths, Capstone is not a CAD tool by industry standards. Here’s why:
- No 3D Modeling or Mechanical Design
CAD software like AutoCAD, Fusion 360, or SolidWorks allow you to:- Create 2D/3D models
- Perform geometric constraints
- Design assemblies
Capstone has no capability to model mechanical parts, structures, or layouts.
- Create 2D/3D models

- No Export to Manufacturing Formats
Traditional CAD allows exporting in formats like:- STL (for 3D printing)
- DXF or DWG (for CNC or laser cutting)
- Gerber files (for PCB production)
Capstone is not meant for manufacturing design, it is experimental and analytical.
- STL (for 3D printing)
- It’s a Data Tool, Not a Design Tool
Capstone collects and visualizes experimental data, but it doesn’t create engineering products or schematics. It’s more comparable to MATLAB’s Simulink or LabVIEW, which also aren’t CAD but are used heavily in engineering design processes.
CAD vs. Capstone: A Clear Comparison
Feature | Capstone Software | CAD Software |
3D Modeling | Not available | Core functionality |
Electrical/Mechanical Design | Limited | Full design suite |
Data Acquisition | Yes | Not a core focus |
Simulation | Real time (limited) | Advanced physical simulation |
Output to Manufacturing | No | Yes (STL, DXF, etc.) |
Use Case | Lab & Experimental | Design & Engineering Manufacturing |
Where Capstone Fits in the Engineering Workflow
Capstone isn’t CAD, but it complements it.
Example Use Case:
- A student designs a robotic arm in SolidWorks (CAD).
- They then use Capstone to collect data from torque sensors and optimize control algorithms during testing.
- Together, they form a closed loop design test cycle CAD for creating, Capstone for validating.
In Education: Why Students Think Capstone is CAD
In university labs, Capstone is often:
- The first tool students interact with during experiments
- Used alongside mechanical structures like carts and sensors
- Involved in visual layouts and system simulation
This leads students to associate it with CAD tools, especially when it’s used in systems design or kinematic testing even though it’s not CAD by technical definition.
Other Tools Often Mistaken for CAD (But Aren’t)
- LabVIEW – For control systems and hardware interfacing
- Simulink – Block diagram based modeling (used with MATLAB)
- Proteus – For electronics simulation (partially CAD)
- Multisim – For circuit simulation (ECAD, not mechanical CAD)
Final Verdict: Is Capstone Software CAD?
No, Capstone is not a CAD software in the traditional sense.
It doesn’t create models, assemblies, or design files the hallmarks of CAD.
However, it is an essential tool in the engineering design process, especially for:
- Control systems
- Real time testing
- Data acquisition and validation
In that way, it plays a CAD supporting role, bridging the gap between design and real world behavior.
No, Capstone is not a CAD software. Capstone generally refers for simulation, analysis, and project management in engineering.
Moreover some Capstone tools are used in mechanical, aerospace, or systems engineering for design verification and optimization, but they are not primarily CAD software like SolidWorks, AutoCAD, or Fusion 360.
Here’s a list of FAQs on Capstone:
