What is CAD Automation?
CAD or computer-aided design automation refers to the automated creation of CAD models through a configuration process, fostering innovation within engineering teams and facilitating sales efforts with precise product drawings.

What is CAD Automation for Manufacturers?
Manufacturers leverage CAD automation beyond mere digital product modeling. CAD provides a comprehensive understanding of a product’s functions through simulations encompassing dynamics, fluid flow, stress, and vibration analysis. This empowers manufacturers to gain precise insights into a product’s performance and proactively detect and address any issues before the manufacturing phase begins.

The complexity of CAD is mitigated through automation. Engineers initially create the designs, which are then automated, allowing non-engineers to manipulate the product while still adhering to the original design’s standards.

CAD also interfaces seamlessly with cutting-edge technology like 3D printers, facilitating the generation of miniature versions of products. Although these 3D-printed models may not be fully functional replicas of the original, they prove invaluable in the planning stages and minimize the risk of customer dissatisfaction.

Benefits of CAD Automation for Manufacturers
Let’s look at the significant benefits of CAD automation in manufacturing:

Efficient configuration
One of the key advantages of CAD automation is the swift customization of products in congruence with customer requirements.

Traditional product configuration processes follow a sequential path involving the customer, salesperson, sales engineer, and engineer, often leading to time-consuming delays and increased error risks. However, CAD automation streamlines this entire procedure into a single, integrated process, enabling customers to view their product drawings in real time during discussions with your sales team.

Cost reduction
CAD automation centralizes product data in a single source and ensures that all teams work from the same data regardless of their roles in the production process. Centralized access to data reduces the cost of errors and returns, thereby minimizing claims expenses.

Accurate designing
The accuracy of CAD drawings is unrivaled, with an almost error-free performance, making it a superior choice for design and drafting.

CAD creates intricate surfaces and complex shapes with relative ease. Achieving such precision and complexity manually through sketching is challenging, but CAD systems’ tools ensure a flawless outcome, providing manufacturers with a significant advantage.

Sales improvement
One of the notable advantages for manufacturers is that CAD integration can expedite the sales process significantly.

With CAD models readily accessible, sales associates can swiftly customize products. The implementation of CAD automation empowers sales associates to efficiently craft custom products within hours rather than the days it used to take, streamlining the sales workflow.

Custom BOM Editor

CADvision Engineers — Tue, 19 Dec 2023 17:17:47 +0000

About the BOM:
BOM is an important feature available in CAD software by default. Even though every CAD software has given the flexibility to the user to configure the BOM according to their requirement, most users want some additional options to be available in BOM. One of our clients was looking for a more powerful BOM feature which will save time and hence increase productivity.

Challenges Faced
There were a range of challenges faced during the course of the project. Few of them are listed below

Sorting capabilities were not available directly in ‘CAD API’ provided UI controls
Only selected columns will be ‘Editable’, which should be configurable. To set certain columns as editable based on user preference was a challenge.
Since the primary key like the part number can also editable, maintaining the map from the BOM row to the part was a challenge
Providing a dynamic highlight of the component(s) in the graphic area when the row(s) is selected was a challenge
Another challenge was excluding the non-topological entities like Dimension, Annotations, etc. while computing the bounding box.
Solutions
After careful consideration of the client need and analysis of the API provided by the CAD system, we decided to develop an ADD-ON inside the CAD system named as “BOM List Editor”. It was also decided to develop the COM component using .Net technology after considering the UI flexibility expected by the client.

Some of the features we included are:

Using the default BOM settings on the first usage of “BOM List Editor”

The list of columns to be displayed can be configured in “BOM Settings”
Shortcut to show “BOM Settings” is provided in “BOM List Editor” UI.
context menu options on in the BOM list for Zoom and Hide Entities
Option to change BOM Hierarchy Level (0, 1, 2… n, ‘All’ and ‘Leaf’)
Option to make certain columns Editable is also provided inside the Settings dialog.
Performance is high even for complex assemblies as the assembly is scanned and the data is cached to avoid repeated scans and hence lags were avoided when the user makes modifications
Exporting to excel along with the column headers information is provided. The checkbox columns are exported as True/False
Properties displayed as checkbox are named with a suffix _BOOL
Automatic size calculation was also displayed as a column in BOM List Editor . Read more about the case study
