    Spatial Releases 3D SDK 2020 1.0.1

    BROOMFIELD, CO, USA, Apr 29, 2020 – Spatial Corp, the leading provider of 3D software development toolkits for design, manufacturing, and engineering solutions, and a subsidiary of Dassault Systèmes, announces the production release of 2020 1.0.1. The release  2020 1.0.1 enables hybrid manufacturing workflows, improved application responsiveness, and enhanced robustness for simulation workflows.




    Enable super-fast review of large models

    Selective import for optimal performance

    3D InterOp’s selective import ability lets you optimize your data preparation application for handling large CAD models.

    Your application can start by just importing the data required for visualization of the large CAD model, which with latest improvements typically takes a few seconds (see details below). This means that your users can start reviewing large models within seconds of uploading them in your application.


    InterOp Workflow


    While your users review the model, your application can start loading exact BRep data in the background. It can also allow your users to isolate and selectively import exact BRep for just a few parts in the large assembly, and continue the workflow without having to re-start the process.

    Solidworks and CATIA together make up the majority1 of the PLM suppliers for C-Design (CAD/CAM/CAE/ECAD). Hence, in the 2020 1.0.1 release, we have radically enhanced the performance of visualization2 import from SolidWorks and CATIA parts and assemblies by up to 17 times. See the performance chart below for more details.

    Expand the scope of your application to enable hybrid manufacturing 

    Expand the Scope of a 3D Modeler

    Operate on hybrid sets of data and perform both additive and subtractive manufacturing processes by leveraging CGM’s exact and polyhedral geometry modeling capabilities.

    Enable your users to work with data designed in a CAD tool or generated by scanning a real 3D object. Prepare geometry for 3D printing by leveraging wall thickness analysis and offset operators to produce light-weight yet printable parts.

    With the 2020 1.0.1 release, the following CGM operators can be used in hybrid workflows:

    Add simulation to your application

    Modular Workflow Solutions

    Spatial’s modular SDKs enable you to add simulation to a new or existing application with minimal development effort.

    Save time to focus on your differentiators by leveraging Spatial’s robust Booleans and meshing solutions for your data preparation needs. Spatial’s solution gives your application automatic CAD Associativity to the mesh, as well as the ability to automatically identify interfaces (contacts) between different domains, so your users can focus on their simulation.


    simulation workflow

    In 2020 1.0.1, we have enhanced the robustness of CGM’s non-regularized unite for exact geometry. It is now better suited to support interface generation and identification between different bodies in a CAD model thus allowing for automation in data preparation for CHT (Conjugate heat transfer), CFD (Computational fluid dynamics) etc. simulations.

    ACIS, a proven modeler, further enhances booleans

    Enhance the Experience of Existing ACIS Applications: Proven Modeler

    ACIS applications are the most proven and robust on the market. With 30 years of continuous development, ACIS provides its customers a stable, flexible and performant experience.

    With 2020 1.0.1, 3D ACIS Modeler is more stable at performing incremental Booleans (iterative Booleans that offer a higher rate of success than 1-step Booleans) when dealing with bad geometry like sliver faces, edge-face near coincidence etc. With a more robust preparation step, incremental Booleans deliver consistent success rates for complex and noisy data sets. This is especially relevant for ACIS based Simulation applications that perform multi-body Booleans.

    Spatial is a solution advisor, not just a component provider

    Enhance the Experience of Existing ACIS Applications: Solution Advisor

    2020 1.0.1 release includes ACIS enhancements delivered as a result of direct engagements with ACIS customers. By leveraging Spatial’s 3D experts in the customer success team, you can get custom implementations done for your needs and strategies or schedule on-site trainings. To get started, contact your Account Manager or reach us at the support portal.

    Some such 2020 1.0.1 enhancements include:

    Up to 65% performance improvements in wrapping a large number of wire bodies on a face (api_wrap) by enabling multithreading. This can allow for real-time marking, engraving or etching of 3D objects.

    Reverse engineer point segments to generate line and arc segments.

    This functionality can enable applications focused on converting scanned data to BRep or exact geometry.


    1. Easy editing downstream
    2. Speed up 3D printing or robotic arm movement
