New features in Live Parts v1.8
Released on December 4, 2018
- NEW Material selection
The Live Parts for SOLIDWORKS Add-in now allows users to specify the material for the Live Parts design in the Settings dialog. Users can now set the material as one of several available pre-set options via the dropdown list, or alternatively, users can set the material to match a component of an existing assembly in SOLIDWORKS by clicking the Add from component option. Properties are exported to the Live Parts design environment, where the designs are generated based on the chosen material and a specified safety factor (which is set to 2 by default and is user-adjustable).
- NEW Embedded finite element analysis (FEA)
Live Parts now leverages a finite element method (FEM) library that performs accurate analysis of stress, strain, and displacement, in conjunction with the existing fast physics engine from NVIDIA and powered by the GPU. As a result, by checking Enable FEM in the Advanced Controls toolbar, users can view a Von Mises Stress or displacement analysis of their smoothed Live Parts design right within the application itself with no need for third party validation tools.

- NEW Rotational symmetry feature
The Live Parts for SOLIDWORKS Add-in now allows users to impose rotational symmetry constraints on their Live Parts design. Users can specify the reference plane and axis for rotation as well as the rotation angle (used to indicate the periodicity of rotation). This new symmetry model allows users to more easily create designs for applications such as gears and wheels.
- NEW Pressure forces
Live Parts now support pressure forces (in addition to rotational and linear forces). With this new feature, users can create thin walled vessels by creating thin attractor gradients surrounding a surface with a pressure force applied.
- NEW UI multi-threading
The Live Parts design environment now runs user interface operations in their own dedicated thread. This enables users to spin around the model while smoothing, exporting, or performing long operations more easily. Users can now also click on controls and obtain immediate feedback, even when frame rates during the growth process exceed 200ms.
- NEW Low strain mode
Live Parts now supports a "Low strain mode" for designs on which users anticipate very light forces being applied. Users can select Low strain mode in the Cell Properties toolbar, which causes Live Parts to automatically lower the strain threshold used to trigger cell growth to an appropriate level to facilitate the successful generation of an optimized design.
- UPDATE Enhanced force expression editor
The Force expression editor in Live Parts for SOLIDWORKS Add-in now includes a template expression which features a random number generator that can be useful for simulating jarring and non-regular forces. The expression can be deterministic, based on a value such as the frame count, and it can be modified both using the Add-in prior to design generation as well as in real-time during the growth process in Live Parts. The expression editor also now allows users to more easily define direction vector expressions as a function of time.
- UPDATE New and updated sample models and assemblies
With the introduction of material properties in Live Parts, we have updated many of the sample models with real-world forces and material properties. Updated models are listed below the LPI Files section of the Examples menubar option in Live Parts. Many of the assemblies in the Live Parts for SOLIDWORKS Add-in have also been updated, including swingarm, skateboard, pedlabox_new, engine, wheel, and more.
