Base Model Created Edited



  • The function that links the degrees of freedom of arbitrary nodes (dependent nodes, slave nodes) to a master node is called a constraint. Through this function, weights can be assigned to each dependent node, or correlation can be set between different degrees of freedom.



From the main menu, select [Structure] tab > [Base Model] group > [Base Structures] > [Truss]

Select the truss type and diagonal pattern.


Number of Panels

Enter the number of truss panels.



Select either symmetry or asymmetry of the truss.



Enter the length of the truss.


H1, H2

Enter the heights (depths) of the truss.


D1, D2

Enter the heights of inclination.


Apply out-to-out Size

"Apply out-to-out Size" permits truss depth dimensioning from the top of top chord to the bottom of bottom chord, rather than dimensioning center to center.


Show Dimensions

Display the dimensions entered in the Wizard Window.

Check-in to add vertical members in span and at both ends.


Merge Straight Members

When vertical members are not added, merge the top and bottom chord segments separated by the nodes allocated for the vertical members.


Show Element No.

Option to display the element numbers for the generated truss.



Option to display the element numbers for the generated truss.

Click ....png to add a new material property or modify an existing material property.



Enter the sections to be used for the top chord, bottom chord, diagonals, and verticals.

Click ....png to add a new section or modify an existing section.


Apply the same material to all members

Assign the same material property to all members.

NOTE.png In Ver. 6.3.0, different material properties can be specified for top, bottom, diagonal and vertical chords.

Fig. Insert dialog box


Insert Point

Enter the coordinates of the insert point where the origin point of the created Truss will be located in the existing model with respect to the GCS (UCS).

Alternatively, click the entry field and click the position of the insert point in the working window to enter the desired coordinates rather than typing in the entry field.


Beam End Release

Release the degrees of freedom of beam and truss members for the connectivity between the members. The ends of beam members are released by default, or the user can release the ends of beam members.


Element No. : Display the element numbers on the screen.

Node No. : Display the node numbers on the screen.

Beam End Release : Display the end release symbols on the screen.

Enter the rotational angles, Alpha, Beta, and Gamma, that will define the orientation of the Truss in GCS X, Y, and Z respectively.


Merge Duplicate Nodes

Select the option to merge overlapping nodes between the existing model and the nodes pertaining to the newly created Truss.

....png : Set a tolerance for merging nodes.


Intersect Frame Elements

Select the option to divide the existing elements at the nodes pertaining to the newly created Truss, which are in contact with the existing elements in the existing model.

....png : Set an intersecting tolerance to allow for the division of elements.


Origin Point

Set the origin point of the newly created Truss. This point is displayed in red in the Wizard Window.


Show No. : Display the node numbers making up the created Truss.
