ath_k3d_form
Routine for quickly inserting a three-dimensional auxiliary construction. You determine the type and dimensions of the auxiliary construction in a dialog box. The construction is inserted into the drawing on the auxiliary line layer. Then you can assign profiles (profile groups) to the axes with the command Apply bar assembly.
Dialog box Auxiliary construction
db_ath_k3d_form
In this dialog box you choose your construction type in the drop-down menu at the top left. After selection, the construction is displayed in a preview. The following constructions are available:
lean-to roof
gabled roof
hipped roof
compass roof
pyramidal roof
domed roof
saw-toothed roof
facade
dormer lean-to roof
dormer gabled roof
dormer hipped roof
dormer compass roof
Once you have selected a construction, enter the dimensions into the corresponding entry fields in the right half of the dialog box. Since the dimensions for the individual types of construction differ, not all of the entry fields are required. These are then masked out in gray.
The dimensions Length, Width and Eaves height can be both entered and displayed. To display a dimension, click the corresponding button with the mouse. The dialog box is then closed and you can specify a length by pointing to two points. Once you have entered the second point, the distance between these points is accepted into the corresponding entry field.
The individual gradients can be specified as angles in ° or as slopes in %. Click the button of the relevant gradient to toggle between ° and %.
The button Baseline is only available in the facade type of construction. Click the button to define the baseline of the facade. You only obtain a preview of the facade when you have defined a baseline.
When you quit the dialog box with OK, the input request follows:
