Keywords Connected with the Openings on Log Walls

The LOGHOUSE setup file may contain the following keywords connected with the openings on log walls.

mach_opening_cut
Defines the machining code for notching an opening (not a machining macro).
opening_extension
Defines the default installation spaces for a window or door on a log wall.
opening_extension = TOP BOT SID
TOP = space above the opening
BOT = space below the opening
SID = space on both sides of the opening. For example, is SID = 20, the opening will be 40 mm wider than the actual window or door.
Installation spaces depending on the size of the opening macro can be calculated with an application development program ../custom/macros/logmach/LOGW_OPEXT.PRG. The width and height of the opening, total height of the opening combination, opening type, code and manufacturer as well as the log width and riser can be used for calculating the spaces. In addition, two parameters (SETTLING and ANGLE) can be used for calculating the settling and installation spaces for slanted openings.
  • SETTLING - Vertical settling space at the top edge.
  • ANGLE - The parameter defines how the slanted edges are handled.
The calculation formulas require a customer fitting.
The default values for parameters TOP, BOT, SID, SETTLING and ANGLE are defined in the LOGHOUSE file.
The size of the installation opening can be defined directly in the opening macro's parameters with the keywords LOGW_OPEXT_T, LOGW_OPEXT_B and LOGW_OPEXT_S. Spaces can be prevented in macro's parameters by setting NO_LOGW_OPEXT=1.
Installation spaces are shown in the model, when the log wall has an accurate presentation.
show_openings
Defines whether the opening macros are displayed in the log work drawing or not. The keyword can have the following values:
  • 0 - Not displayed
  • 1 - Displayed
The keyword will only affect the visibility of the opening geometry in the log work drawing. Log walls are always cut with the opening macro when the log work drawing is opened. When the drawing is closed and saved, the change is also updated in the model.
