How can I copy a component from one project to another ?
What version of SketchUp?
Please complete your profile.
Several ways…
Assuming a Desktop SketchUp version...
Open both projects from their SKP files.
In the source-project, select an instance of the desired component and then select Edit > Copy.
Now go to the destination-project and use Edit > Paste - pick to locate the copied instance [alternatively use Edit > Past-in-Place for it to arrive in the same location as the source-project]
In the source-project open the Component Browser and in the model-pane select the required component, right-click > context-menu > Save as…
Now you can import it from that SKP into any new project.
Similar to 2. but select a placed instance of the component and right-click > context-menu > Save as…
In the Component Browser’s model-pane use the pop-out menu and choose ‘save as a local collection…’, this will include all current components as separate SKP files
You can then use the converse pop-out menu item to load a collection or an individual SKP into any future models…
If you are using the Web-based version you can upload to 3dWarehouse and reuse it elsewhere...
