Hello,
Thank you for your help, and apologies for not replying before I have been out of the office reason why I can only reply now.
@Alfredo_Medina, thank you for confirming "Transparency of glazing elements is not available", I am new to Revit and was not aware of this for "Elevation views".
@torresdiver92,thank you for detailing how to modify the transparency of elements, step by steps, without your feedback I did not know how this could be achieved. You made it easy to follow, great, Tx.
@Keith_Wilkinson to reply to your question : yes for this project, and for those Elevations I needed to doors open. I tried as suggested to edit the family, and have no idea as to why it was not possible to hide those doors when imported into a project (and see the furniture inside the house, which was what I was trying to achieve like in 3D view). I tried via 2 different ways:
- by adding a "Visibility parameter" yes/no as occurrence to the doors when in. No go: you still can not see inside, the furniture placed in the house.
- 2nd method I tried while in the family still, was to play with the "Visibility parameter" for the door itself and unticked : show : front/back left/right, as well as plan view and medium details as well as high details. No go: you still can not see inside, the furniture placed in the house). No idea why the last method did not work. Thanks anyway, this could have worked.
The last comment I would like to add if someone one day is in the same situation, and if it helps : I found that the default wall opening (for doors, and for Windows too, I believe the system/outcome is the same) is not enough to see through the house.
If you need to represent and see the furniture inside (in Elevation mode), it is best to delete this default wall opening in the Family editor, and replacing it with a good 'old' VOID. (Yet so obvious but did not think to do so, believing the default wall opening was enough for Elevation views). This was the/my solution. Simple efficient and now you can see through.
Thanks again to the 3 of you for your help !
