Clients Overview

TransMagic is a leading CAD translator capable of opening, viewing, and querying all major 3D CAD formats. Renowned for its precision and versatility, TransMagic also empowers users with advanced dimensioning tools to add linear, angular, and radial dimensions to a variety of geometries, including vertices, edges, arcs, planes, and cylindrical surfaces.

Project Overview

ProtoTech Solutions partnered with TransMagic to enhance their dimensioning tools by implementing and refining three types of dimensions:

  • Linear Dimensions
  • Angular Dimensions
  • Radial Dimensions

Additionally, the tools now support edit and move functionality, enabling users to adjust inserted dimensions with ease.

Challenge

One of the key challenges was implementing a Linear Dimension for scenarios where two arc entities are selected. This required careful consideration of various measurement options to ensure accurate and user-friendly dimensioning.

Solutions

Our team developed a dynamic interface that allows users to select their desired dimension type for arc entities, offering the following options:

  • Tangents of Two Arcs
  • Centers of Two Arcs
  • Tangent of One Arc and Center of Another

We also introduced a Part-to-Part Authentication feature, enabling users to compare master and derived models for accuracy, ensuring design fidelity.

Dimensioning Features

1. Linear Dimensions

Linear dimensions are inserted based on the following selection types (see Fig. 1):

  • Single linear edge.
  • Two vertices.
  • Two parallel linear edges.
  • A linear edge and a vertex.
  • A planar face and a vertex.
  • Two curves/non-linear edges (Fig. 2).
  • A curve and a linear edge (Fig. 3).
  • A curve and a planar face (Fig. 4).
2. Angular Dimensions

Angular dimensions are inserted when the following selections are made (see Fig. 4):

  • Two non-parallel linear edges.
  • Two non-parallel planar faces.
  • A linear edge and a planar face that are not on the same plane.
3. Radial Dimensions

Radial dimensions are applied in the following scenarios (see Fig. 5):

  • Single arc or nonlinear edge selection.
  • Circular or cylindrical face selection.

Benefits

This dynamic dimensioning tool significantly enhances the user experience by making dimensioning:

  • Intuitive and Efficient: Users can quickly add the most appropriate dimension type based on the selected geometry.
  • Flexible and Precise: The edit and move functionality allows for easy adjustments, ensuring perfect alignment and accuracy.
