Traditional CAD systems often frustrate engineers with hardware limitations – slow performance on complex tasks, lengthy renders, simulation crashes, and costly workstation upgrades. This hardware dependency has been a burden in product development ever since computer-aided design and engineering software went mainstream.
Onshape, PTC’s cloud-native SaaS platform, fundamentally changes this by leveraging immense cloud computing power as its core engine. Unlike traditional systems requiring specific hardware, Onshape integrates robust cloud resources directly.
This power is always included, driving demanding features like large assembly visualization, rendering, simulation (FEA), and CAM without local machine constraints or hidden cloud token costs.
Modern engineering is compute heavy. For example, a designer might want to check that all mates are correctly defined in a complex assembly such as this jackhammer model. With Onshape, animating mates of a complex model or looking at the section view of the entire assembly is a delightful experience because the compute heavy workload is handled on the cloud.
Similarly, an engineer might want to check the factor of safety or static stress in a critical system such as this piston assembly in the jackhammer.
Onshape utilizes GPUs in the cloud to solve this static structural analysis rapidly without locking up the engineer's local machine.
Finally, the machinist in the team might want to simulate the toolpath and check for collisions before machining a component such as this connecting rod. They can do so rapidly on the cloud with Onshape.
With cloud-native CAD and simulations, engineering departments are no longer required to make large upfront IT investments to keep up with modern computing trends, only to see long deployment times and ultimately frustrated end users.
With Onshape, cloud computing is always built in and accessible for an accelerated product development cycle.
Cloud Computing: Your CAD Engine, Not Just Storage
In Onshape, intensive product development tasks run on powerful, remote cloud servers (powered by AWS), not your local computer. Instructions are sent to the cloud for heavy processing, and results stream back. This decouples performance from local hardware specs; your device acts as a portal. Demanding tasks run effectively even on modest devices, democratizing access to advanced CAD capabilities.
It's crucial to distinguish Onshape's cloud computation from simple cloud storage or "cloud-hosted" solutions. Many platforms merely store files online or stream a desktop app, retaining file-based limitations (check-in/out, locking, latency) and reliance on local processing. Onshape's cloud-native architecture uses a database and performs actual computation (rendering, simulation, geometry) on scalable cloud servers, enabling transformative benefits passive storage cannot.
Why Cloud-Computing Matters for CAD Users
Integrating cloud computing as a foundation provides tangible advantages:
Accessibility: Access your full CAD environment and compute power from anywhere, using any modern device (browser or mobile app). Work from the office, shop floor, or on the go.
Seamless Collaboration: Real-time, simultaneous collaboration is inherent. All users access a single, centralized data source and shared compute, viewing/editing designs concurrently with live updates. Eliminates file-based delays and conflicts, accelerating design cycles.
Zero IT Overhead: Eliminates significant IT burden. No software installations, manual updates, servers, license managers, or complex on-premise deployment. Onshape manages the backend, freeing IT resources.
Cost-Effectiveness: Predictable subscription includes access to necessary cloud computation. Offers lower, more predictable Total Cost of Ownership (TCO) compared to traditional CAD's hidden costs (hardware, separate software/PDM, IT, downtime).
No Hardware Bottlenecks: Performance for compute-intensive operations comes from Onshape's scalable cloud infrastructure (AWS), not local hardware limits. This lowers the barrier to advanced capabilities and reduces capital expenditure on hardware.
Computer Hardware No Longer a Bottleneck
Heavy workloads that locked up resources or, worse, crashed computers are a thing of the past. Onshape uses specialised hardware on cloud for respective workloads, and multi-threads the processes so users can keep working while the heavy workloads finish running.
Visualization & Motion: Traditional CAD is sluggish with large assemblies locally. Onshape offloads geometry/visualization to cloud servers for smooth, real-time manipulation of massive assemblies on any device.
Rendering: Traditional rendering requires powerful local hardware/software and ties up machines for hours. Onshape Render Studio generates high-quality images in minutes within Onshape. Onshape has access to specialized GPUs that speed up rendering workloads.
Simulation (FEA): Traditional FEA is computationally intensive, needs high-end local hardware/separate complex software. Onshape Simulation integrates linear static/modal analysis, solved efficiently on cloud servers with interactive results that update with design changes.
CAM (Computer-Aided Manufacturing): Traditional CAM toolpath generation is computationally demanding locally, separate software causes version/transfer issues. Onshape CAM Studio integrates CAD/CAM/PDM, using cloud compute for calculations.
Cloud Computing: It's Not an Add-On, It's the Foundation
Onshape's cloud-native architecture integrates cloud power as a fundamental utility, unlike traditional CAD systems that require costly add-ons. This integration optimizes workflows by centralizing data and mitigating complexities in file management, which frequently cause errors and delays. It also eliminates local hardware limitations, enabling engineers to operate from any device with internet connectivity.
This paradigm shift cultivates seamless collaboration, facilitating concurrent work on the same design, real-time feedback, and expedited design iteration for rendering, simulation, and CAM. By furnishing scalable computational resources, Onshape streamlines access to advanced tools, diminishes IT overhead, and empowers engineers to concentrate on innovation and accelerate product development, thus yielding more efficient and cost-effective product lifecycles.
