Clients Overview

TransMagic is a leading integrated CAD translator designed to open, view, and query nearly all major 3D CAD formats. It provides advanced tools for positioning parts precisely in 3D space, making it an indispensable solution for digital mock-ups and virtual prototyping. With TransMagic, users can seamlessly import parts from multiple CAD formats, align them accurately, and build complex assemblies with precision.

Challenges

When implementing advanced features for assembly models, our team encountered significant challenges. A critical API from the geometric kernel, essential for handling modified transformations at the component level, was not functioning as expected due to known limitations. This posed hurdles in achieving accurate transformations during assembly model operations.

Solutions

To tackle these challenges, we devised innovative solutions:

  • Mathematical Workaround: To ensure accurate transformations, we employed advanced mathematical calculations, bypassing the API’s limitations.
  • Precise Positioning: Our implementation allowed users to align parts with unparalleled accuracy using various methods such as axes, planes, and radii.
  • Customizable Movements: Both linear and angular adjustments could be made intuitively or by entering precise values, giving users complete control over part placement.


These solutions are showcased in Table 1, which details the intuitive interface and the robust functionalities of the Precise Positioning tool.

Benefits

The implemented solutions delivered transformative results:

  • Accurate Part Placement: Users can position parts exactly where needed, ensuring seamless assembly workflows.
  • Enhanced Digital Mock-Ups: Perfect for virtual prototyping, these features streamline the creation of realistic and functional digital assemblies.
  • Time Efficiency: Reduced time spent on manual adjustments, enabling faster project completion and improved productivity.
Align Planes
Fig.1: Align Planes

(The target body gets transformed to align the selected target face with the selected source face.)

Make Concentric
Fig. 2: Make Concentric

(The target body gets transformed to match the center of the target entity with the source entity.)

Make Parallel
Fig. 3: Make Parallel

(The selected body gets transformed to put the target entity in the same plane as the source entity.)

Point to Point transform
Fig. 4: Point to Point transform

(The target body gets transformed by applying the transformation from the source vertex to the target vertex.)

Fig. 5: Linear Transform

(Using linear transformation users can linearly transform the target body along X, Y, and Z axis.)

Fig. 6: Rotate transform

(Using the Rotate transform users can apply the rotational transformation by rotating the body along X, Y, and Z axes but the linear transformation is not allowed.)

Point Transform
Fig.7 : 3 Point Transform

(The target body gets transformed by applying transformation from three selected source vertices to three selected target vertices.) 

Freeform
Fig. 8: Freeform

(Using this tool user can freely transform the body anywhere in the view without any limitations.)

Mirror
Fig.9: Mirror

(Mirror transformation is applied to target face along the selected face/edge.)
