Modeling and Data Preparation for Digital Dentistry: CGM Polyhedra Enables Easy Undercut Filling and Tooth Cap Generation

New in 2022 1.0, CGM Polyhedra introduces the ability to create a smooth blend between the boundaries of two meshes and the ability to sweep polyline profiles with a draft angle.

Tessellated models composed of meshes are ubiquitous in modern workflows across various industries. For example, consider the dental industry, which largely consists of organic anatomical shapes, unlike precise solid-geometry normally seen in traditional engineering design and manufacturing applications.

CGM Polyhedra has robust tools to both heal and modify mesh-geometry, including new functionality to fill gaps between meshes and create/modify meshes by sweeping polylines with draft-angles. This new functionality, in conjunction with existing healing functionality in CGM Polyhedra, allows Digital Dentistry application developers to easily develop workflows such as:

• Fill open regions in the form of irregular holes that may be a result of poor upstream scanning in tessellated models of jaws.
• Fill concave undercut regions between the tooth and the jaw with poly extrude and sweeps.
• Smoothly join the tessellated model of a crown (tooth-cap) with the tessellated model of a root (tooth-root) by filling the region between the boundaries of the two meshes.

Overall, the three digital dental workflows are simplified with new functionality in CGM Polyhedra. Further, the new healing and modeling functionalities in CGM Polyhedra are applicable for industries beyond Dental.

Unbending of Sheet-Metal Parts with Even More Speed: Automatic Unbending

In 2022 1.0, CGM Modeler introduces a new operator to automatically detect cylindrical bends and automatically unbend them in 3D models. As a result, and when combined with existing operators in CGM Modeler, software developers can enable robust and efficient automation in sheet-metal manufacturing applications.

Often sheet metal is the obvious choice for a myriad of industrial uses. An important step in fabricating sheet-metal parts is the ability to virtually reverse the manufacturing process to unbend digital sheet-metal parts and lay the original sheet-metal design flat. Then, features can be removed, and the exact size of the sheet-metal blank can be determined and optimally nested within standard sheets for automatic cutting.

Sheet-metal parts can now be automatically unfolded with CGM Modeler. The selected flat-planar face can be inputted into the new automatic unbend operator in CGM Modeler, which will automatically traverse the part, detect all bends, and unfold each bend. Once the original design has been unfolded, the exact size of the sheet-metal blank can be determined. Afterward, the end-user can select the material, and fabrication costs can be determined. Finally, the sheet-metal part can be fabricated and delivered to the customer.

The entire virtual workflow for importing sheet-metal parts and unbending such parts can be implemented into any CAD-CAM software application with Spatial’s powerful CGM Modeler.

Obtain Finite-Element Results Faster: Creation of Mid-Surface Sheet-Bodies with the 3D ACIS Modeler

In its latest release, the 3D ACIS Modeler introduces the capability to extract sheet-bodies at the mid-surface between faces of solid bodies with the new function api_make_mid_sheet_body.

A good example is a finite-element (FE) workflow in a computer-aided engineering (CAE) application. The new ability of the 3D ACIS modeler to easily and quickly extract the mid-surface between opposite faces of thin-walled geometries greatly simplifies FE-workflows.

Instead of a series of manual modeling operations to extract the mid-surface for each pair of opposite faces, the CAE-application activates an ACIS-enabled workflow to extract the mid-surfaces. The resulting sheet-body can then be meshed with structural shell elements, using Spatial’s 3D Precise Mesh, resulting in a mesh to which appropriate boundary conditions and loads can be applied and a solution ultimately obtained. All without time-intensive manual modeling operations to extract the mid-surfaces.

Easy-to-Implement Parallelization in the 3D ACIS Modeler: Quickly Multi-Thread Your ACIS Workflows

In 2022 1.0, 3D ACIS Modeler introduces a new “helper” function, api_process_mt, which greatly simplifies the implementation of multi-threaded, largely independent workflows involving ACIS data and functions.

While parallelization of patterns seems straightforward in theory, up until now, it has been quite difficult to implement in ACIS-enabled applications because of the relationships between geometric and topological entities in solid models and the need to track modeling steps in history streams.

For example, consider an ACIS-dependent workflow that entails the subtraction of a half-space in a model with a large number of bodies. Subtraction for a single body requires about ten lines of code without multi-threading. And for multiple bodies, with the new helper function api_process_mt, only ten additional lines of code are needed for subtraction in a multi-threaded manner.

The new helper function api_process_mt in the 3D ACIS Modeler can be used to quickly parallelize many common ACIS-dependent workflows via multi-threading without resorting to the ACIS Thread Manager. An excellent example of using api_process_mt to multi-thread an ACIS-dependent workflow is Spatial’s own implementation of the new function api_n_body_clash in the 3D ACIS Modeler to detect clashes among multiple bodies.

With multi-threading, api_n_body_clash is significantly more performant than api_body_clash. Moreover, api_n_body_clash is more versatile than api_body_clash in that it detects clashes among more than just two bodies.

From Smaller to Larger with 3D InterOp: Import of Large-Scale Models into CGM-Based Applications

Large-scale models are typically associated with BIM-centric applications, which consume data for landscapes/terrains and buildings, whose dimensions range far outside dimensions for traditional CAD applications. New for 2022 1.0, 3D InterOp allows the import of large-scale models with dimensions ranging from 1-100km into CGM-enabled applications. Such capability extends the capability of CGM Modeler (CGM) from traditional mechanical-design workflows to architectural, engineering, and construction (AEC) workflows in the field of building-information management (BIM).

Furthermore, 3D InterOp offers the import of small-scale models with dimensions down to 10µm into CGM-enabled applications. This additional capability for small-scale models extends CGM into the semiconductor, electronics, and precision electro-mechanical industries. 3D models can now contain features ranging in dimensions of several mm to a few meters for fixtures in rooms to many kilometers for the terrain – all enabled with large-scale functionality in 3D InterOp for CGM-enabled applications.
