I have a townhouse project that will have various front facade options per unit floor plan. What is the best way to handle this? That will make several combinations of several attached units forming a building. Each building will have townhouses with various combos of elevations per building.
If the only thing different about the unit is just he front wall then it is a shame to create a whole file for each option to hotlink. It is a shame no formal design option feature like i hear they have in Revit.
You can make the source modules in the same file as the townhouses or altogether in a separate file.
If you make the façades in the same file as the buildings you can either model them all remote from the project or chose one of each "in situ" to use as the source for each. These can then be made into modules by selecting all the elements (easy if they are grouped) and using "Save Selection as Module".
If you don't want the complications of having the source in a different part of the main file or to remember which in situ façade is the source of each you can model them all in a single separate file and use the same method to save the modules.
There may be a way to set up the modules as a publisher set but this would depend on the details.
