Solution to data conversion problems
Just like other serious problems, there are two possible solutions: prevention and treatment. There are two measures to prevent. First, correctly guide those responsible for creating data to correctly understand the requirements and possible application of these data. Secondly, provide tools to automatically identify those problems before they cause serious problems; treatment is through A conversion tool with model patching capabilities solves model import problems.
1. Prevent from the source of CAD
The 'reality' problem is avoided by the user's careful modeling, model quality checking, and the specification of certain processes and procedures to prevent the generation of some unrealistic features at the outset. With the continuous advancement of CAD software, patches Defects and more robust programs reduce the number of failures and undesired defects in the modeling process.
The 'system' problem is also being improved. The software is now developing in a mutually understandable direction. Everyone pays more attention to each other's special requirements, but it seems to be problematic, even if all CAD systems are based on the same modeling kernel, all software sharing. Data format and internal structure information, system problems will still exist for some time.
The 'precision' problem is still the most serious problem because it is constrained by the entire software framework unless you change the entire framework of the software or adopt a new modeling kernel, which is considered from a business perspective.
2. CAD model quality check
In fact, many serious downstream problems arise from small design errors that seem trivial in CAD. For example, a small error caused by a Boolean operation may generate a small geometry, which causes the mesh algorithm and the tool path generator. It produces errors, but in fact it is perfectly reasonable in a CAD system. Such mistakes are too easy to happen and may be difficult to avoid in design.
Model quality and design inspection tools provided in the source CAD system can be used first. These inspection tools can be run in batch mode or generate graphical inspection reports on the CAD model to show all designs that users believe may cause synergistic problems. problem.
Some short edges, narrow faces, and poor faces can be corrected if they are recognized early. The simple repetitive work of upstream users can greatly improve the quality of downstream received data. Studies have shown that if there is a suitable quality check tool at If the upstream is used, it can reduce the 10% of the repetitive workload of downstream users.
In order to prevent more problems that may be caused in downstream applications, a CAD model quality inspection mechanism can be implemented. Prudential provides a solution specifically for such problems. Through routine diagnostic checks, it is clear that those errors occur. And by whom.
The other focus of concern in model checking is to reduce the size of the CAD file. Models with quality problems usually consume a lot of memory. These checks can be used to find problems caused by unreasonable modeling methods, and even some due to the modeler. It is caused by itself, so through the quality inspection, CAD developers can give back some valuable information and let them improve the system.
3. Repair and repair
Although you use CAD quality inspection tools in upstream applications to avoid some of the synergistic issues, there are still many problems, such as the exchange process itself, automation, and conversion issues discussed earlier. Relying on this automatic non-interactive exchange tool can sometimes make things worse and make users feel overwhelmed.
The solution is to use a data exchange tool that provides an intelligent automated model processing tool that combines powerful interactive geometry patching and manipulation tools and services.
Prudential provides professional data exchange tools and services to help customers gain the ability to input data from different data formats and systems, automated or interactive model patching, model simplification tools, and specific output to different systems and data formats. Tools and options, these data exchange tools can be used and developed by downstream 're-users', in-house specialized training experts, CAD developers, consulting services companies, and growing web-based application service providers.
