I'm a Revit expert with +8 years experience and high proficiency, above all I'm a skilled parametric families developer, I follow the best practices for my content to be effective but lightweight.
Here's an estimate of the amount of time needed to build a custom library:
- preliminary setup and planning for the first family of a group of similar objects: from 2 to 4 hr
- development of each single family can take an average time of up to 1.50 hours.
Much depends on how many groups of similar families we have, of course.
The step file attached can be imported in Revit but will remain a fixed solid geometry (useful as a reference anyway); if we want the object to flex, it is necessary to rebuild the geometry with Revit elements, whose dimensions can be driven by parameters. In this way, we can describe a variety of devices within the same family, all these for example: [login to view URL]
Any other data such as electrical wattage, sound rating and so on can be included as well.
I will consider 80 $ for the first of each group + 40 $ for each next product regardless the number of different types.
For instance:
80 $ for Hand Dryers Category, 40 $ for each next hand dryer
