Dear all, this is my first post so I want to say hay and thank You in advanced for Your help. My name is Matija and I’m from Croatia… My company name is LIGHT ON and we are a small lighting design studio.
At the moment I’m searching for a solution for the next problem:
We are developing a project for a Hotel with approx 3000 luminaires (which we already planned in dwg). At the moment I’m trying to develop a Dynamo process to place the family instances automaticaly based on x,y coordinates extracted from the dwg.
The ceiling height’s in the hotels are different (and the ceiling are actually just generic model mass, so no family with ceiling host works, but face hosting should be used).
I managed to assembly a dynamo process that works fine for x,y placing, and even finds the ceiling height, but does not place the family on that place - instead of that, it is placed upside down on the floor (please see the picture).
Please be so kind to let me know what I’m missing…
Dear khuzaimah.ElecEng, thank You for Your answer…
Do You mean flipping the family with the little icon by it’s side (the one on the photo)?
If so, when clicking it, does not happen anything…
Sorry for not mentioning it before, You’re all welcome to suggest a different approach for finding the soultion…
I think my approach is not perfect, because having the ‘Select model elements’ node, I have to select all the ceilings in the hotel to make it work,so it’s a messy work…
Dear Phh,
thank You for Your answer…
unfortunately we got the exported IFC from ArchiCad which when exported, generates generic models for all the ceilings… so basicaly all the ceiling hosted luminaires should be only face based…
That’s the reason why I cant select all the ceilings by category or family…
Hy Alban_de_Chasteigner,
thank You for Your help…but as I already mentioned…unfortunately we are dealing with some generic mass ceiling,so I cant filter the ceilins by category…
tnx
throughout my experience in similar situation, there is a problem when you want to set a location for any ceiling hosted family with Z axis … it won’t work and you cant even change its host after Run. i suggest to try not to use hosted family, use elevation parameter instead
If you insert the dwg at the level, you will find the face of the floor. You need to project the points vertically into the ceiling. Look into rayboumce methods to find the ceilings above your points.
Jacob, that was my first idea, projecting the xy coordinates vertical on the ceiling surface…and that actually works (please see my first photo), but the families don’t attach/place on that projected point, and instead of that they stick on the floor - upside down…
