Project typesFollowing project types can be created and processed: Projects can be converted to different type too (e.g. using a 2D model as a template for more sophisticated 3D modelling). 2D projectPrimary property of a 2D project is given by geometric modelling done in two dimensions only. Only one planar slice is entered and the resulting two dimensional construction calculated. There is no input regarding the third dimension  i.e. coordinates of the axis perpendicular to project plane. This project type is typically used to model a linear thermal heat bridge.
Final 2D Projekt contains ordered sequence of elements. The order of elements is relevant, because later entered elements will partly or fully overlap elements earlier in the order if covering common plane area. Note: Internally AnTherm represents the 2D model as a single layered 3D project with the thickness of exactly 1000 mm  i.e. 1,0 m  in Z direction.
This dependency shall be considered if, e.g. for some result display, two dimensional contractions are modelled in three dimensions. Remark: To support graphical entry the underlay can be registered and shown within the plane of Elements2D window. Remark: The 2D Project Type will be often uses as a starting point for creating 3D models by various conversion capabilities (see below). Layered 3D projectPrimary property of a layered 3D project is given by its geometric modelling of planar slices consecutive to each other (slices itself are identical to a 2D project type). This project type is typically used to model a point thermal heat bridge.
Three dimensional model is given by assigning a thickness to each
such planar slice.
Final "layered 3D project" contains ordered series of layers. The sequence can be controlled by the layers list.
Note: A three dimensional model will result in exactly same results as its two dimensional counterpart only, and only if, the geometry and conductivities do not change along one dimension and the extent in this direction is exactly 1000 mm  i.e. 1,0 m. Remark: To support graphical entry the underlay can be registered and shown within the plane of Elements2D window. 3D projectPrimary property of a 3D project is given by entering all three coordinates in three dimensions directly. The resulting geometry of building construction is described by series of cubes. This project type is typically used to model a complex point thermal bridge. The order of element cubes in the sequence is relevant, because later entered elements will partly or fully overlap elements earlier in the order if covering common space area.
Note: A three dimensional model will result in exactly same results as its two dimensional counterpart only, and only if, the geometry and conductivities do not change along one dimension and the extent in this direction is exactly 1000 mm  i.e. 1,0 m. Remark: To support graphical entry three underlays can be registered and shown within respective planes of Elements23 window quadrants. Converting between project types
