Miscellaneous configuration entry

Configuration(s): wall programs: single slab schema

'Miscellaneous' tab

Secondary bars - show groups:

Showing bundled secondary bars:

Region: the program shows 1 bar fully from a bundle of secondary bars and shows the others by an area line.

1 bar: the program shows only 1 bar from a bundle of secondary bars.

All: the program shows all the bars in a bundle of secondary bars in full.

Wall thickness shown in addition:

When you check this box, the wall thickness is shown in the sheet header (ELEMENT No. ##, d = ##.# cm).

Center of gravity symbol:

Center of gravity marking on EPA:

None: no information about the center of gravity.

*: the lifting points (always a ¼ panel length outwards from the center of gravity) are marked with a ' * ' symbol and dimensioned horizontally.

CG: the center of gravity is marked with the code CG and dimensioned horizontally.

Patterned upstands:

You can specify here whether upstands are displayed as patterned or not.

'Details' tab

You have the option of automatically creating enlarged detailed drawings of congested areas in the wall or single slab schemas.

First the program creates the schema for an element as usual. Then the program locates the complex parts of the drawing and prints them on to one or more additional sheets.

You can adjust the various parameters on this page to produce the desired effects on the output of this "detail generator".

This enables the detail generator.

Weight: Lines:

Weight: Text:

Weight: Mark numbers:

A grid, the mesh size of which you can set using the parameters below, is placed over every drawing. Every object under the grid is given a "weight". If the object cuts through a grid cell, then the weight of this object is added to the weight of that square. In this way every grid cell gets a total weight. This is evaluated in the manner described below to detect a detailed section.

Grid length x-/y-direction [cm]:

You have the opportunity to alter both the length and width of the grid cells placed over the drawing. The cells can be increased or decreased in size so that all the cells overlaying the drawing are complete cells.

Number of bits for each partial area:

As explained above, every cell is given a total value made up of the number of objects cutting it multiplied by the weight allocated to them. The program needs to reserve space in computer memory for storing each individual sum. In order not to use up too much memory, you can limit the space required for a sum.

The computer stores these values in binary form. One Byte (consisting of 8 bits) can store 28 = 256 different states, as each bit can recognize the states of 0 or 1. In a similar way, a bit string of 5 bits can store 2^5 = 32 different values. The calculation must also take the number 0 into account, which means 31 is the highest value that can be represented.

This the grand total of a cell cannot be larger than

(2^number of bits) -1

The number of bits must be consistent with the weights of the individual objects.

Creating the detail:

Test area width [cm]:

Starting density [%]:

Largest sum for detail:

To create the detail the program uses an "observation region" in which the magnification can be adjusted using Test area. The magnification can be varied only for whole cells. An average value is calculated from all the cells in the observation region. If the density is greater than the adjustable Start density, the program starts to create the detail. Then the neighboring cells are tested in the observation region. If at any time the grand total for all the cells found up to then exceeds the current setting for the largest sum for detail, or if there are no neighboring cells that have densities greater than the start density, then the program has found the area to be shown in greater detail.

Enlargement factor 1 : x:

Here you can set the enlargement factor for the detailed areas found. 2.5 means 2.5 larger than the original plan.

Extend detail [cm]:

The detailed area can be further extended in cm. This results in the an area of this width around the detail being shown as well.
