3D CAD Data Translation / Repairing
Product Data Quality Solution Overview
GD&T, Tolerance Stack-up Analysis:

iSquare promises to provide best services at highly competitive costs.  Our services range from Consulting, Training Dimensional Control Procedure Implementation, Process review and suggestions. DCS, USA is committed to support iSquare or work jointly for large and demanding services in Dimensional Management.

Dimensional Variation Modeling:-
Creating base line tolerance model based on customer’s tolerancing schemes and assembly processes. We review the input and perform statistical and root cause (HLM) analysis to bring the part issues upfront before investing into expensive tooling, fixtures and gages

Dimensional Requirements Management :-
The "roll-down" of final product interfaces’ Dimensional Technical Specifications used in establishing major system and sub-assembly requirements and evaluating concept alternatives for meeting quality objectives for fit, finish and functionality.

Variation Simulations:-
Three-dimensional tolerance analysis aids in developing robust designs that minimize dimensional variation. When used for defining and managing products’ functional tolerancing and coordinating their measurement data, 3D tolerance analysis significantly reduces the rework required for engineering drawings, tools and gages.

Current production troubleshooting:-
identifying specific contributors, either from the product or the process, and rank critical components tolerances contribution & impact on the total cumulative variation, enhancing product quality while lowering costs.

3D CAD Data Translation / Repairing:-

3D CAD Data Translation / Repairing:- iSquare provides high quality CAD Geometry healing and translation services focused around robust products from TranscenData, USA. The input (bad) geometrics can be simply surface models having problems such as missing topology, holes, untrimmed surfaces and so on, or unconnected solid model that needs to be properly stitched into usable solid model.

Our suite of translation and repair tools developed by TranscenData allows designers, analysts and engineers to exchange their CAD/CAM/CAE data quickly and easily, eliminating up to 90 percent of data rework. Our translation and healing solutions offer numerous advantages and support:

  • Multiple CAD imports
  • Batch processing
  • Intelligent model repair and healing
  • Automatic processing Wizards
  • User-controlled model Defeaturing
  • Interactive fixing tools
  • Multiple CAD/CAE exports

We designed the unique 5 stage wizard within our translation and healing solutions to accommodate novice, occasional and experienced users, so translations and repairs requiring manual intervention can be completed with minimal effort:

  • Diagnostic results are explained and illustrated in clear, accessible language
  • Problems are color-coded according to severity
  • Users are guided through a choice of solutions
  • Model diagnostics are automatically updated after each repair

Process Automation:-

The key benefit of our 3D translation and healing solutions, centers on processes which guides users effortlessly through the import, repair and export process, requiring minimal, manual intervention.

Many of our users like to keep it simple - model translation is as straightforward as choosing the file and a target system and letting our solution do the rest.

However, with the vast array of automatic and interactive processing tools available, we enable the user to address almost every issue affecting CAD geometry, effective translation and downstream reuse, such as:

  • Stitching models
  • Creating missing geometry
  • Building solids
  • Setting tolerance deviations/requirements across different systems
  • Identifying and correcting serious surface definition problems
  • Reducing the complexity of geometry for downstream applications

Deliver Quality Translations throughout the Entire Process

  • It is not just about translating and fixing. Clients can tailor our solutions to check product data quality (PDQ) using a comprehensive library of PDQ tests.
  • Users can also specify the PDQ tests for assessment and set the controlling parameters and tolerances as needed. The completed test then guides the user through a list of potential resolutions to address the quality issues.
  • This type of quality analysis automatically identifies entities in the model that fail to meet the requirements of the selected PDQ criteria and presents the results to the user both graphically and in a text report.
  • Our quality analysis components also offer customization for in-house policies and/or international PDQ standards such as SASIG, VDA and JAMA.

Product Data Quality Solution Overview

Solution Summary: Our product data quality solutions combine leading expertise in interoperability process improvement, with innovative technology.  Our core offerings solve specific problems stemming from this basic premise: we identify design quality and interoperability software issues that need to be resolved to improve downstream re-use. 

Our Methodology: Each engagement is carefully planned and executed, to ensure that the customer realizes a significant return on investment. If a production implementation introduces custom requirements that require some incremental development to address, we work to mitigate those risks to develop a solution that meets your needs and delivered on time and under budget.

Solution Delivery: Customers view our unique expertise and innovative technologies as a long-term, strategic application of best practices, tools and process improvements. Our solution is not designed to be a tactical, short-term, problem-solving tool. The usage scenarios in which CADIQ may be applied are typically complex and varied. Our expertise will help you simplify the upfront analysis of your particular problem and accelerate the implementation of a solution that meets your needs.

The Technology: Our technology, known as CADIQ, focuses on identifying geometric conditions that impact the reuse of a design model in downstream applications, especially simulation and tooling.  It includes a subset of the PDQ geometry criteria that address basic integrity, accuracy and complexity and contains several diagnostics that identify unrealistic geometric conditions that are clearly “design defects” because they are outside most practical design intent requirements.

Our technology is also unique in its ability to compare the form, properties, topology, shape and quality of a set of two, three or four equivalent models.  These models can be any combination of the nine supported CAD system or neutral file formats.  The graphical feedback is provided in a unique user interface that synchronizes the views of the models being compared while simultaneously highlighting the comparison issues in each view.

Customers comment, in particular, on the easy-to-use interface, with graphical controls that can be dynamically configured to behave like any supported CAD system and can synchronize the CAD system display with our display on demand. The solution has a rich command line interface for integration into automated customer environments.  It generates statistical metrics that directly support process quality improvement programs.
