TREE MODELLING _ PLATANUS  (PIAZZA DELLA RADIO)

 

We had chosen a Platanus tree situated in Piazza della Radio. This sort of tree is typical of urbans areas.

He can be very tall, and this one is 14 meters high. Its trunk make 0,5 meter of diameter and the foliage 12 meters.

Due to its size and to its foliage this tree has a strong impact on facades surrounding. But losing its foliage in winter, its influence is reduced.

Diagram:

We cut the tree in differents levels, and estimated the various diameters of the trunk and the foliage.

Modelling:

We open a new family file, to create the tree as a new family. We choose the mass file.

Before modelling, we had to change the units, we opened the "project units" window.

And we changed the units (meters, and unit symbol: m)

Then, we had to create the differents levels of the tree as the figure above.

For that, we put the view in elevations (east), and clicked on Model/Level to create new ones.

We created 8 différents levels corresponding to the various sections of the tree.

After that, we drew circles in each level, representing the diameter of the foliage for every section. For that we put the view in plan.

We had to be careful drawing it on the good levels.

Once completed, we obtained the silhouette of the tree

It only remains to create the shape of the tree by connecting the dots circles between them.
For it, we had to select all the circles and clicked on:  Create Form / Solid Form.

And we obtained a new volume created according to the various elements which we had generated:

hello, very good post!

It misses the "use" of the tree in a urban vasari model, to test if its "arboreal mass" really simulates and generates a space (and shade) really similar to the one observed in the city. Rome is full of beautiful streets featuring several Platanus. Does your model simulate well these spaces?

Or just the one of your photos?

Also you have to attach the tree file (.RFA) to the post to have a completed submission

thanks,

S.C.
