DTAS Dimensional Tolerance Analysis & Dimensional Chain Calculation – A powerful modeling tool for user-driven assembly

Thread Content

The independent development of relevant industrial software and systems represents a critical bottleneck that needs to be addressed urgently for intelligent manufacturing and quality improvement. Tolerance analysis software systems, on the other hand, are key to precise design in early-stage quality development, as well as to cost reduction and efficiency enhancement. Today, we will explore how to use Python scripts and the DTAS API to implement personalized assembly logic and tolerance simulation analysis. Anyone can be a tolerance analysis programmer; anyone can create their own custom assembly solutions. DTAS 3D offers a wide range of assembly modes tailored for different application scenarios. Users can directly utilize these standardized assembly modes to carry out rigid, flexible, and dynamic modeling in an efficient manner, meeting over 95% of modeling requirements. \"User-defined assembly\": The basic logic of user-defined assembly is to select relevant features and write Python scripts for the assembly logic oneself. In Python scripts, the DTAS keywords target and object are used to retrieve information on relevant features, such as coordinates x y z, directions i j k, diameter, etc.; these pieces of information are then used to develop the assembly logic. The result of the assembly logic is essentially a rotation and translation matrix, which the user writes into the “RotateAndPanList” keyword list. For example: Take the assembly of a single part along the directions of two features as an illustration. Users can create their own custom assemblies through DIY without requiring professional programming skills. It is mainly divided into 3 steps: Step 1: Establish the required feature points in the assembly and the target part: O1 and T1 are used to create the assembly point O1, while T1 is used to create the target part point. Step 2: Similar to other assemblies, manually select the relevant features that are involved in defining the target part. In this example, for assembly part O1 and target part T1, Step 3: Write a Python script and define a reference to this script in this assembly. •]Video demonstration summary: DTAS can utilize Python scripts and DTAS APIs to implement customized assembly logic and tolerance simulation analysis, making dimension modeling more enjoyable, creative, and rewarding. We invite all DTAS users to try out this new feature and to share their experiences with us.
