Parameter transfer, also known as the eye-dropper and syringe, is the easiest way to pick up the parameters of one element and transfer them to another element of the same type. Simple usage of these tools allows you to speed up your pace while drawing your project.

What is better about parameter transfer is; you are able to control the set of additional settings (“Transfer Set”) which should be transferred: basically, you can configure sets at Element Transfer Settings, and apply the Set you need during Parameter Transfer.

Workflow for Parameter Transfer

Eye-Dropper works as a picking tool for the parameters of base element. Syringe on the other hand, “injects” the chosen parameters to the target element.


This operation can be implemented in plan, elevation, section and 3D views. You can find a detailed explanation for this operation in the following link:

Parameter Transfer Inside a Library Part

If you created a custom window, door, object etc. and don’t want to lose your time to customize other elements’ parameters, you can use Eye-Dropper and Syringe in the Object Settings dialog box. You can find the detailed workflow for this operation in the following link:
