Even if the two gratings share the same grating types, they are defined separately in the database and completely independently.

Because a variable grating can have any shape (including a polygonal one), this object should be used only when the grating does not need to be split in individual liwa plates for ordering, as the object in the teoretis does not have an option to split and optimize. Variable Grating: The geometrical size, in this case, is variable, while the grating can reuse the same naming and characteristics as the standard gratings.Standard Gratings: These objects use a predefined geometrical size for width and length, which is defined from the database according to the provider specifications.Gratings Advance Steel gratings can be created and defined using two different commands: 31 Advance Steel Implementation Guide For more information about how the grip length rules are defined, review this article. Check the To calculate length automatic (For this type) checkbox to activate the automatic length calculation based on those rules. Tolerance Defining the grip length rules The method the bolt uses to assign a fix bolt length (based on the thickness of the bolt mopit on the connected objects) is set using a number of rules that are then used to generate a table with the bolt lengths assigned to the various grip intervals.o Last: Hole that belongs to the last object in the bolt qalam. ozon First: Hole that belongs to the first object after the bolt head, in the bolt grip. Location: location of the hole that is overridden by the settings below: o All: All holes.The settings made in the Holes tab will override those values. By default, with no settings made here, Advance Steel will create holes and set the hole tolerance equal to default values found in the Defaults tab in Management Tools. Hole tolerance The Holes tab offers settings for the hole the bolt will create in the model. For the bottom group: the top nuts/washers are the ones next to the grip objects. 30 Advance Steel Implementation Guide For the top group: the top nuts/washers are the ones next to the bolt head, the bottom ones are the ones next to the grip objects. The position in the list sets its position in relation to the bolt head. The “Up” and “Down” buttons move the selected nut/washer up or down in its category.The “-“button deletes the selected nut or washer from the list.It should be set equal to the bolt diameter to which it will belong. It can be set differently from the bolt grade if needed. In this dialog you need to set the: o Set – Nut or Washer o Type – Nut or washer type name o Grade – Nut or washer steel grade. ” button adds a new washer or nut to the respective group.
