Drill - Dimensions tab

SettingDescription
Layout Selects the general form of the drill hole field.
  • Single – Allows the position of each hole to be determined individually.
  • Radial – Arranges the drill holes in a complete or partial circle around the insertion point. Additional input fields are displayed allowing you to define round drill hole fields.
  • Rectangular – Arranges the drill holes in a rectangular pattern around the insertion point forming rows and columns. In general, drill hole fields are described as follows:
    Number1*Pitch1, Intermediate Pitch1, Number2*Pitch2, Intermediate Pitch2,...
Shape/X Dir Enabled for the Rectangular hole layout. Defines the drill hole field pattern in the X-direction of the UCS.

Example 3*1,2,2*.5: 3*1 defines first three columns of holes with X spacing equal to 1, 2 defines the intermediate X distance between the 3rd and 4th column of holes, and 2*.5 defines the last two columns of holes with X spacing equal to .5

Cross/Y Dir Enabled for the Rectangular hole layout. Defines the drill hole field pattern in the Y-direction of the UCS.

Example 3*1,1,2*.5: 3*1 defines first three rows of holes with Y spacing equal to 1, 1 defines the intermediate Y distance between the 3rd and 4th row of holes, and 2*.5 defines the last two rows of holes with X spacing equal to .5

Num/Radius Two value fields are enabled for the Radial hole layout.
  • Num field - Defines the number of drill holes.
  • Radius field - Defines the radius of the circle where the drill holes are arranged around the insertion point.
Area/Start Two value fields are enabled for the Radial hole layout.
  • Area field - Defines the angular range in which the drill holes are distributed.
  • Start field - Defines the start angle from which the drill holes are distributed.
Diameter Specifies the bolt diameter. You can select from the predefined list of diameters or enter a value in the field.
Tip: Predefined values are saved in an editable file: C:\Program Files\Bentley\ProStructures CONNECT Edition\ProStructures\Default\appl\MechanicalFasteners\Bolts\pro_st3d.hdt.
Workloose Sets the clearance between bolt diameter and hole diameter. Disabled when Create Threaded Hole is checked.
Note: The value you enter here, can defined as a global workloose for bolt diameters. To do this, activate Use Clobal Workloose in the Global Settings Bolts tab.
Slot Length Defines the length of the slotted hole axis. If Slot Length is set to zero (0), a circular hole is created.
Hole Layout
  • Drill Through – Holes completely penetrate the material.
  • Drill Blind Hole – Holes are drilled to a entered depth. Enables the Hole Depth value field.
  • Weld Mark – Creates small depressions for locating welds.
Hole Depth Specifies the depth of blind holes. Enabled when the Drill Blind Hole hole type is selected.
Hole Position Selects the flanges to be drilled. You may either drill holes into the upper or lower flange or into both flanges.
  • Upper Chord – Holes penetrate only the upper flange.
  • Lower Chord – Holes penetrate only the lower flange.
  • Both Chords – Holes penetrate both flanges.
Note: Upper/Lower flanges depend on the position of the component part and the active Z-axis.
At Shape Center When on, the insertion point is perpendicular to the shape center. This ensures symmetrical drill holes relative to the shape center.
Create Threaded Hole When on, threaded holes are generated. The threaded holes are represented in 2D drawing views.
Add drills to a part Select to insert drill holes into a component part. You then select a part, which is then drilled accordingly.
Add drills to multiple part Select to insert drill holes into several component parts simultaneously. You can select several parts at the same time. The alignment is made based on to the first picked part. Disabled for Single layout.
Copy drills from one/more part to other part(s) Select to adopt the drill holes of one component part into another one. To do this, first select all the shapes with holes to be transferred and then all the shapes to adopt the holes. This way drill holes from a copied connecting plate may be rapidly transferred to a shape. This option is only available if you didn't select the option Bolted Connection.
Tip: Press and hold <Shift> during component part selection, and you can select a component parts in referenced models.

Top view (upper) and side view (lower): 1) drilling hole, 2) these profiles are drilled as well, 3) imaginary beam

Tip: You can also adopt a drill hole field with simultaneous bolted connections into a new shape so the new shape is drilled first and then bolted. To do this first open the shape properties (right click > PS Properties), and select the edit tool (magnifying glass) in the Modification > Holes tab. The Drill dialog opens where you can adopt the drill holes with bolts, select (Add parts to a bolting) in Bolts tab.
Preview Dynamically displays the design of the drill hole field and the insertion point prior to applying it to a shape.
