Overview - Dynamic sectional drawing
Section view is one of the most important features of computer aided architectural designing.
The section view is derived from the model of the building and appears as a new drawing in accordance with the model. The program generates the section view in a new 3D window, perpendicular to the cutting plane.
You can create as many section views of a building as you like. The section view dynamically follows the changes made in the model.
In the section view you can select each element and you have access to the architectural objects. You can change objects in the section view as well as on the floor plan.
Section view can be combined with vectorial shadowing and with vectorial hatching but it requires longer generation time. Vectorial shadows can be calculated from the sun or from an arbitrary angle.
The representation of the section line is defined by a standard that is acknowledged in the field of technical drawing. The section line is a dotted-dashed line with letters (the section’s letter symbol) and with arrows at the ends, which show the direction of the section view.
Moving, rotating or mirroring of the section line with the use of section line markers on the floor plan refreshes the section view automatically.
The section line is visible on the view where it was created.
There section view enables the visualization of objects crossing the section plane with or without material hatches and with thin or thick contour lines.
In the ARCHLine.XPâ out of the dynamic sectional drawings the following opportunities are available to create different kind of sections:
Static section
If you did not work out the model in detail, the section provides a good basis for further editing.
With the help of the program’s clipboard, you can copy any 3D viewsor sectional views to the floor plan window. The copied drawing loses its connection with the 3D model, therefore it can be freely edited, the view or section can be ”dressed up”. For instance, you can specify the order of layers, which you have to indicate on the plan, but it was not represented on the model. With this option the program provides considerable freedom to the designer.
Stepped section in a 3D section window
Section line can be created in a 3D façade view (vectorial drawing) window, too, even in a stepped form. In that case the newly created section window will include a stepped section.
Cutting a 3D model
You have the possibility to cut a model with a stepped section line and display the result on a rendered image. This command really cut the 3D model.
Dynamic cutting plane
Applying the dynamic cutting plane in an OpenGL image window, you can represent the dynamic section in real time. This representation is very useful, not just for aiding the architectural design work, but for a spectacular representation of the building to the customers, too.
