WIP: Create a model using vertical sections

docs/workflows/create.md

 # Create a model
 
+This section describes how to create a new model in **IGMAS+** using a "traditional" workflow using "vertical planes" (vertical sections).
+Historically, the idea was to construct the model along seismic lines, which acted as constraints on the modelling.
+This approach was used for a very long time until the transition to building the model using horizontal planes (flying carpets), such as Moho interface, intra-crustal layers, etc.
+The "flying carpet" approach is described in the [Import horizons](import.md#import-horizons) section.

 ## Creating a Simple Model
 
-This function is available only if there is currently no model loaded.

 In the **Menu Bar** select ++"File"++ --> ++"New Project"++
 
-This is the function to create a new project. There are two possible ways of creating a project:

+There are two possible ways of creating a project:
 
 1. New Model: build a new model
-2. Horizon Import: build a model by importing layer surfaces (horizons) - this way is explained in [Import horizons](import.md#import-horizons).

-Set the origin (X, Y), the size (Width, Height) and the depth (Depth). Don’t forget to choose the units (m / km). Default is X,Y = 0,0; Width, Height = 10,10 and Depth = -5. Change the values according to your needs and click on ++"Next"++.
