Bevel properties for predefined bevels

The system administrator can define predefined bevels in System Management > Construction > Welds/Bevels > Predefined Bevels.

You can adjust the properties of predefined bevels while inserting or modifying single bevels in the 2D-Contek & 3D-Contek and Shell applications, in the Bevel dialog which opens when you start the insert or modify function. The Predefined tab is active when you start the functions. Select the predefined bevel that you want to insert, or to apply if you are modifying an existing bevel.

The bevel properties are grouped into tabs, as follows:

A Settings tab is available in the in the System Management application for defining how the bevel should react on different plate thicknesses.

Bevel tab

Depending on the selected bevel type, the Bevel dialog displays a different set of settings and options. Only the settings and options that are applicable for the selected bevel type are shown.

The options are as follows:

  • Bevel type – Set the type of bevel to be applied. See Bevel types.

  • Angle – Set the angle of the bevel.

  • Bevel – Sets the height of the bevel.

  • Nose – Sets the height of the root face.

  • Join bevels – When selected, forces the same value for Bevel 1 and Bevel 2.

  • Angles are relative – Switches between relative and absolute bevel angles. A bevel on a plate can be relative to the construction that the plate is touching. When the plate is touching slanted and curved construction, the start and end angles of the slanted construction are used to create a bevel that runs from one end to the other linearly.

    The example below shows a deck connected to the hull. A V bevel is used with an angle of 0°. The slanted lines indicate the shape of the hull to which the plate is related. Line A shows the angle of the hull at the start and line. Line B shows the angle at the end of the bevel.

    These angles are also shown on the dialog.

  • On entire relation – Determines on which part of the plate edge the bevel extends. Two plates in the same plane can have different lengths, resulting in two possibilities for the length of the bevel to be applied. When selected, the entire length of both plates are beveled. When cleared, only the real connection between the two plates is beveled.

    In the case of the image below, selecting On entire relation will result in a bevel on plate 1 on the entire magenta line. When not selected, the result will be a bevel only between points A and B. For plate 2 there is no difference.

Construction angle

Construction angle is the angle between the beveled edge of the plate and the side of the other plate touching the beveled edge.

With V bevels, the construction angle is the average of the angle at one end point of the bevel and the angle at the other end point of the bevel. For example, if the construction angle of the beveled plate edge to the conneted plate is 19.4° at one end of the bevel, and 52.9° at the other end of the bevel, the construction angle is (19.4°+52.9°)/2 = 36.15°.

  • With V bevels, the construction angle is subtracted from the bevel angle when the bevel is a V+ bevel, and added when it is a V- bevel

Whether the construction angle is positive or negative depends on which side the angle is located, relative to the view direction.

  • The angle is positive if it is located on the side opposite to the view direction.

  • The angle is negative if it is located on the side of the view direction.

See Angles in the different connections.

Taper tab

Enable and modify tapering properties of the bevel. The settings and options shown wary according to the selected Position.

The options are as follows:

  • Position – Enable or disable tapering, and set the position on the plate where the taper is applied.

  • Height – Ses the height of the taper.

  • Factor / Angle / Width – Set the angle of the taper, the width of the taper, or the width/height ratio for the taper.

  • Specify by – Set which of the three settings above are shown in the dialog.

  • Join tapers – When selected, forces the same values for Bevel 1 and Bevel 2.

The system will adjust and choose the taper according to the situation. When the correct taper for the situation is not known, you should define the taper on both sides.

A taper will be added to the production data when the thickness difference is more than the taper setting. Taper information is always available at the drawing level.

Weld tab

Modify the weld connection settings of the bevel.

The options are as follows:

  • Method – Select the weld method. The available options are set in System Management > Construction > Welds/Bevels > Weld Codes, in Weld Codes, Second Part, Func.descr. for each weld code.

  • Throat – Select the throat height of the weld (mm). When Automatic is selected, the system will calculate throat height automatically based on Weld factor rules.

  • Connection – Select a condition for the plate connection.

Opening tab

Modify the bevel opening settings. Bevel opening makes the plate smaller.

  • Size – Set the size of the weld opening (mm).

  • Division – Divides the opening between two plates.
