Structural Steel Design SoftwareDesign with structural steel or profile? Creo Advanced Framework eXtension allows one to completely design 'intelligent' fully-parametric structural profile constructions for building, utility companies, mining and other industries. These structural profile designs can then be fully integrated with other mechanical design aspects which make up the larger PTC Creo design system. The following simple demonstration uses PTC Creo Elements/Pro AFX Advnaced Framework Extension for structural profile design of a simple shed.

As a prerequisite for following the steps of this multi-part tutorial, have Creo Elements/Pro EFX installed and licensed, have basic Creo training for sketch and 3D modeling and understanding of structural steel principles. (For more information about Creo Elements/Pro or a demonstration license in Australia please contact CADDIT at this LINK.)

Creo New CAD Drawing

Step 1. Create a New Assembly...

  • Top Menu > File> new> select assembly from the type options> select design from the sub-type options > edit name of the assembly ‘EFX_ tut’ > use default template> click ok.

Step 2. Create a New AFX Project...

  • Top Menu > EFX 7.0> project> create new project> edit project shortcut ‘EXF portal frame’ > enter.

Step 3. Begin with a Simple Creo Line Sketch...

  • Create a simple line sketch representing the layout of the first frame structure.
    Select the sketch tool from the right tool chest> the sketch dialog box will appear> select the ‘asm_front’ datum plane, the ‘asm_right’ datum plane will automatically be selected as the reference> select sketch. See the Creo Sketch guide and tutorials for examples of creating a simple line sketch in Creo - Pro/ENGINEER.
  • Create the sketch similar to our example in figure 3 below:

  • (Top Menu) EFX 7.0> profiles> the profile dialog box will appear, under the assemble tab choose the ‘select profile from library’ tool> select the Steel Beams MM file> select the I-Beam, the element definition dialog box will appear> select Australian UB, this will then bring up the list of sizes> select the 460UB82.1> the profile dialog box will appear as shown in fig. 4 (right)
  • Select the ‘assemble new profile instance’ icon under instance type> select the ‘assemble profile on a straight curve or edge’ under the reference method> select the ‘assemble profile at centre’ under the position option.
  • Select the ‘asm_front’ datum plane (profiles need to run parallel to the selected plane) > select the first vertical line on the left, the profile will then be generated as shown in below fig.5 below:

  • Choose the ‘select standard and size for the profile’ tool> select the 200UB18.2 beam> the instance type, reference method, position and datum reference plane are as 4.1> select the assemble profile rotated by +90 degrees’ under the rotation option.
  • Select the second vertical line on the left, the profile will be generated> repeat for the next vertical line.
  • Choose the ‘select standard and size for the profile’ tool> select the 460UB82.1 beam> select the ‘assemble new profile instance’ tool under the instance type option> select the ‘assemble profile without rotation’ under the rotation option> select the right roof line, the profile will be generated> repeat for the left roof line. See fig.6 below:

Structural Steel Profile Joints Step 5. Adding Structural Profile Joint 

Select the corner joint (see fig.7 left)> select the left vertical 460UB beam> select the 460UB rafter, the joint will be generated (see fig.8) > repeat for opposite end.

Select the Mitre joint> select the left rafter> select the right rafter (see fig.9)

Select the T-Joint> select the 200UB vertical beam> select the rafter (see fig.10):

Select the endplate align size (see fig.11)> check the with holes option> change hole dimension>select (1) profile top> select the top face of the rafter> select the (2) attach face>select the inside face of the vertical beam, connection will be placed (see fig.12)> repeat for opposite end.

Endplate align size> enter values (see fig.13) check (a) with holes, select (1) profile top> select the outside face of the vertical beam> select (2) attach face> select the rafter, connection will be generated. Repeat for next beam: 




 Step 7. Mirroring an Existing Sketch

  • Create datum plane> offset front datum plane by 7000mm> select the sketch> select the mirror tool> select ADTM1 and mirror the sketch. (see fig.15)
  • Create other end of the frame now by repeating Steps 4-6 on the new sketch
  • Further profiles can be added by refering to steps 4 - 4.3 for adding the profiles (see fig. 18)
  • In this case, select the 100x5 SHS> new instance> Assemble profile between two points (see figure.17)> select reassemble existing profile instance>select the SHS> Select between the two points. (refer to fig.17)
  • Create a new datum planes> offset asm_top plane by 3000mm, offset asm_right plane by 5000mm> create a new sketch> select the ADTM2 and select the ADTM3 as your reference with the orientation set to ‘top’ > create the sketch as shown in figure.19

Step 8. Final Assembly

  • Add the 100PFC profile and T-Joint as shown in fig.20 (refer 4 and 5 for method)
  • Select the 1 Angle connection> select 100x10 from the ‘profile size’ options> place connection to PFC as shown in fig.21 (refer to 6.Connections for method)
