Yes, it's possible. There are some model objects that do not have a visible structure. For example, the most popular place now is the city of Bandits. If you scan the chairs that stand in the playing hall where the big wheel is, you will see that there are visible chairs models "chair.static" and invisible models "chair.invisible". When copying the visible chairs, everything will be as usual. But the sofas themselves are just a picture. They can not be copied or moved. And inside of them are ordinary invisible chairs. When copying sofas, you copy only the invisible chair. )) And when you insert, you will not see anything at the insertion point. Only the name of the object.
It will be difficult to get rid of invisible walls. If you know exactly where these walls are, then you can see the name using the tool, although nothing will appear before you. I do not know which walls you copied. Even the invisible walls may not interfere, but what was copied from the environment. Perhaps this is an object, maybe even water, only it is the back of the structure to you and it is invisible, but the sound you hear.
In order to scale out the space from all strange objects, it is necessary to build up this place with the structures of buildings, a large foundation and there are many many walls on it. You can build two or better three floors in this way. And then using the command "/ remove all" from another plugin, delete everything. Then, together with the construction, invisible objects are removed.
Jake Rich, I really like your tool! It opens many opportunities for non-standard construction! )))
I would like to offer a small addition. That would be very useful!
there is a problem with the rotation of the structure. It is impossible to rotate the object perfectly evenly. Is it possible to make so that the control of the object would be carried out EXTRAORDINARY, for example, with arrows of the keyboard? To filter unwanted movements in a different plane!
For example, I drew a picture that explains the words.
Usually, when trying to rotate a structure in one plane, this does not work for the first time (((((
For example, with the Shift key, the shape would rotate faster. But simply the arrows were a great positioning accuracy.
I also would like to make a different turn step or snap to degrees. Then you would not have to lose half an hour to join the edges of two objects ..
