Macro animates switching of configurations using SOLIDWORKS API

{% youtube { id: t35Kjjq509w } %}

Macro demonstrates how to create an animation from configurations using SOLIDWORKS API.

This could be useful when it is required to create an animation to represents model history or sheet metal folding.

• Open part or assembly
• Select configurations in the order they should be animated

{ width=350 }

• Run the macro. New assembly created with configurations set as animation steps.

{ width=450 }

Macro parameters (time of the bend transition and pause between folding operations) can be changed by modifying the constants at the top of the macro

Const TRANSITION_TIME As Double = 0.5
Const PAUSE_TIME As Double = 2

Refer the Suppress Features In New Configurations for a macro to create configurations from features.

Const TRANSITION_TIME As Double = 0.5
Const PAUSE_TIME As Double = 2
