I have already managed to select the squares which was in the connected same elevation.
Now I give you a little bit different but similar task. How would you select the area of the “island” in the red circles but leave a small border around it? I mean to select almost all titles but leave about 1-2 “border” non selected. Here by “border” I do not mean the edges, but the faces which are on the border of the island. By other words, the titles which are near the green background of the image, should not be selected, but the inner of the island yes.
The island is all same height.
I have found this process to select border of faces:
Select -> Faces By Face
Select -> Bounding Edges (This operation takes a lot of Time! Cca 10 minutes)
Select Only -> Selection border
Select -> Connected Faces
To select the area without border I would need to invert the selection (in the faces which are in the island). Is it possible?
I tried: Invert Selection
This is the moment when i would like to save the selection before I deselect the rest of model.
A moment of tension. I must be very careful while deselection. I do not want to suffer heart attack when I would do a mistake and deselected all.
And here is the result:
After I selected the area at image above, I have moved the entities up +4.5m. Then I can repeat the process above with s small change:
The area which is selected is not that big.
After step 4. I will fill it by different material because I cannot repeat the invert selection now.
Then I deselect all and click again in the same place with select->Connected by Material.
This result in this selection:
Which selects the area which I want to move up. And i can repeat this process as many times I want.
