Log Cross Section Library

Edit the cross section library in the database view. You can add a new cross section to the library by copying and editing the data of an existing cross section. Move the cursor over the row to be copied and select Edit > Copy Row from the menu bar of the database view. The program will add a new row to the database and copy the contents of the fields on the row you selected to the new row, excluding the code. Type a name for the cross section and fill in the rest of the parameters on the database view tabs.

Code

Type the name of the cross section in the Code field.

Type

Select the type from the list.

• HH = planed log
• PH = round log

If the type is not selected, it will be determined by the code name.

• A code starting with PH represents a round log.
• Other codes represent a planed log.

Cross section, Accurate

The shape of the cross section is defined using an application development program. Type the name of the application development program in the field. The program should be located in the ../proflibrary/log directory. The software developer offers the following application development programs:

• PLANEDLOG - cross section of a planed log
• ROUNDLOG - cross section of a round log

You can also draw the cross section in a drawing file. Name the drawing file according to the cross section type and size, and save the file in the ../proflibrary/log folder. When you draw the cross section, note the location of the drawing origin in relation to the log profile riser: the origin must be located exactly at the middle of the riser. Add a hatch fill to the area limited by the profile edge lines.

H = log profile height

NETH = log profile riser

When you are defining the data for a new cross section, type the drawing file name in the Cross section, Accurate field.

Cross section, Coarse

The coarse shape of the cross section is always defined using the COARSELOG application development program. The program should be located in the ../Proflibrary/Log directory.

Corner length

Type the length of the log wall corner in the field. When you are adding a log wall with the profile in question selected as the log, the parameter value is set as the default corner length. Select the edge that determines the corner overlap in an oblique corner from the first list. Select one of the following as the measuring method from the list:

• 1 - Shorter edge
• 2 - Longer edge
• 3 - Center line

Select a wall line from the second list from which to measure the corner overlap:

• 0 - measure from the center line of the wall (A)
• 1 - measure from the exterior surface of the wall (B)

Log dimensions

Type the dimensions of the log cross section in the Width, Height and Net height fields.

The height of a round log should be as defined in the application development program generating the cross section. For example, in the ROUNDLOG application development program, the log height is calculated as follows:

H = N/2 + W/2

where

N = log net height

W = log width

Notch

The width of the crib is, by default, the same as the width of the log. If necessary, you can type a value for the crib width that is smaller or than larger than the log width. When the field is empty, the default value is used.

Base log height

Type the heights of the base log in the Full and Half fields. The Full height of the base log may be smaller than the Height of the log.

When defining the height of the bottom half log, take into consideration how you want the risers of crossing walls to be positioned in relation to each other. If, for example, you want the riser of the half base log to be half of the riser of the full base log, the height of the half base log will then be

Hp = (Ht - a)/2 + a

where

Hp = height of the bottom half log

Ht = height of the lowest full log

a = the settling space part of the log profile

Lumber

Type the dimensions of the log billet in the Width and Height fields.
