Add components to assembly using SOLIDWORKS API

Edit ArticleEdit Article

This example Demonstrates 2 different ways to add component into the assembly tree using SOLIDWORKS API.

  • Traditional way to add component via AddComponentX SOLIDWORKS API requires the model to be loaded into the memory. Otherwise the operation fails.
  • More advanced way is to use the AddComponents SOLIDWORKS API. This method allows batch insertion of different components without the need to open the model beforehand.
