Dimensioning Rules - Overview (3-D SE)

Dimensioning rules can be divided into different groups:

In the Dimensioning Rule Editor the dimensioning rules can be filtered by these groups.

Clear distances between posts

If the clear distance between two posts is dimensioned as individual dimension, the post thickness will not be considered. The dimensioning takes places in all fields of the railing segments. If the dimensions of the rule are not equal in all fields, only the dimension of the first field will be depicted.

In dimension type Chain of dimensions the post thickness will be taken into consideration, too. If the chain of dimensions of all fields is equal, only the chain of dimensions of the first field will be depicted.

Distances between post axes

The axis distance of two posts is dimensioned in all fields of the railing segment. If the dimensions of this rule are equal in each field, only the dimension of the first field will be depicted.

Clear distances between rods

If the clear distance between two posts is dimensioned as Individual dimension, the post thickness will not be considered. The dimensioning takes places in all fields of the railing segments. If the dimensions of the rule are not equal in all fields, only the dimension of the first field will be depicted.

Recommended setting for rule 1008

In dimension type Chain of dimensions the post thickness will be taken into consideration, too. If the chain of dimensions of all fields is equal, only the chain of dimensions of the first field will be depicted.

Distances between rod axes

This rule dimensions the axis distance between posts and vertical rods as chain of dimensions. The dimensioning takes place in all fields of the railing segment. If the dimensions of the rule are not equal in all fields, only the dimension of the first field will be created.

Angle Post - Handrail

Example 2:

The oblique segment of the depicted staircase has individual distances for posts and vertical rods as well as different post and vertical rod thickness. Hence, dimension and chain of dimensions of rules 1006 to 1009 are not equal.


Notes on dimensioning rules

Base points on hidden sub-parts

In the file STW_DIMSETTINGS.XML you can specify how base points on hidden parts are to be handled when using dimensioning rules. To do this, enter the following string into the file:

</PARAM><PARAM Name="IGNOREHIDDENSUBPARTANDBORES" Typ="INT" Value="0">

If Value has been set to 1, base points that are located on hidden sub-parts will not be considered for dimensioning in all dimensioning rules.

 

Attached sheet/plate parts or plates and beams bordering on relevant beams*

When dimensioning attached sheet/plate parts or plates and beams that border on dimensionally relevant beams, both contact points will always be dimensioned. If only the first contact point in the chain is to be dimensioned, open the STW_DimSettings.XML (conventional dimensioning settings) file in the HiCAD sys directory and set the parameter

</PARAM><PARAM Name="SUBPARTPOSITION" Typ="INT" Value="0">

to 1.

This setting affects all dimensioning rules marked with an asterisk *.

 

Example - (1) without change of the STW_DimSettings.XML , (2) with change of the STW_DimSettings.XML

 

Separate chain dimensions for different usages

You have the option to create separate chain dimensions per different usage for chain dimensions describing the fitting situation of parts. To change this behaviour, open the STW_DimSettings.XML (conventional dimensioning settings) file in the HiCAD sys directory and set the parameter SEPERATEDSUBPARTPOSITION to 1:

</PARAM><PARAM Name="SEPERATEDSUBPARTPOSITION" Typ="INT" Value="1">

The image below shows a beam with 4 plates for different usages (1=Front plate, 2=Reinforcement plate, (3) Stiffener) and the front view of the production drawing.

If the STW_DimSettings.XML file does not contain the described parameters, you can also make manual entries as described above.

 

Separate dimension chains for bores and subtractions

In the Dimensioning Settings it is now possible to determine under Bores/Boltings that separate chains of dimensions should be created for bores (through holes and standard bores) and subtractions. For this purpose there is the Separate dimension chains for bores and subtractions checkbox.

For new installations or when the dimensioning settings file STW_DIMSETTINGS.xml is not yet available, the stab3par.dat option can be switched on and off under

Maßketten für Lage der Bohrungen/Ausnehmungen trennen nach Bohrungen und Ausnehmungen 1:ja, 0:nein

If the STW_DIMSETTINGS.xml file is available, the line

</PARAM><PARAM Name="DEVIDEBORESANDCUTS" Typ="INT" Value="1">

has to be added.

This settings will not yet be saved in the workshop drawing at this point!

 

Please note that this setting also affects the following dimensioning rules:

Bores in upper and lower flange of beam

Bores in sheets/plates, right or left side

Bores in sheets/plates, upper or lower half

Outer contour of sheets/plates, right and left side, in sectional views

Beam processing in web, incl. processings in side view

Beam processings in upper and lower flange, incl. processings in side view

Bores in flanges of relevant beam sub-parts

 

Example - Separate chains of dimensions for bores and subtractions

The depicted drawing (1) contains several through holes bores and one rectangular subtraction. (2) separate chains of dimension, (3) one chain of dimensions for bores and subtractions

In the example the following settings for dimensioning rule 12 have been used for (3):

 

Separate dimensions according to part type for position of sub-parts

In the Dimensioning Settings it is now possible to determine under General that attached parts (beams) will be dimensioned according to the Part type attribute in the different chains of dimensions. A respective checkbox is available in the dialogue window. In this way it is possible to dimension hollow profiles / attached parts separately from round steel / attached part, thus improving the dimension structure.

This setting affects dimensioning rules for chains of dimensioning of relevant parts.

For new installations or when the dimensioning settings file STW_DIMSETTINGS.xml is not yet available, the stab3par.dat option can be switched on and off under

Separated chain dimensions according to part type for position of sub-parts 1:yes, 0:no - Getrennte Massketten nach Teileart fuer Einbausituation von Nebenteilen 1:ja, 0:nein

If the STW_DIMSETTINGS.xml file is available, the line

</PARAM><PARAM Name="SEPERATEDSUBPARTPOSITION_PT" Typ="INT" Value="0">

has to be added.
