Question
I want to change the shape of the User Section.
Answer
There are three ways to modify the shape information of a section.
In CIM, Path Linked Entity and General Member are created based on the User Section created in User Section Mode.
If errors are corrected or a change element occurs during the modeling process, you can enter the User Section and modify the section information of the object.
User Section can be entered and modified by directly clicking on the Works tree or the corresponding object.
As mentioned above, the User Section is used to create an object by defining the section information as a single piece of information.
Dependent objects such as reinforcing bars are created based on points and lines in this section information.
Therefore, if you modify the section of an object created through User Section, even if the model is changed
Rules for dependent objects such as reinforcing bars can be maintained and automatically correspond to the modified object.
In addition, it enables editing and application of multiple objects created with one User Section with one edit and edit.
There are three main ways to modify the shape information of a section.
To change the section shape through user parameters, set variables in User Section Mode and
It is to modify the section information by directly entering a value or setting a formula.
Figure 1. User Parameter
If you set a parameter in User Section Mode, you can check it in Assigned Parameter in the upper mode.
In other words, when changing the shape of a section using user parameters, the upper mode is displayed without entering User Section Mode.
Section information can be edited immediately.
By using the library to which the corresponding user parameter is applied, it becomes a model Easily manage and modify multiple models.
The biggest advantage of the cross-sectional shape change method through user parameters is when the parameters are linked in the upper mode.
It means that it can respond to changes in the user section to which user parameters are applied, external vertices, and other members.
For example, if the user parameter is set when the height of the column and the cross section of the foundation need to be changed
The point is that you can set the shape of the foundation section to change automatically just by adjusting the height of the column.
The following is how to change the shape of the section by using the Modify function of Edit after entering the User Section Mode to edit the section information.
It deforms by moving the edge or vertex that composes the section.
Figure 2. Modify Move Edge/Vertex
As mentioned above, how to use Modify to change the shape of the cross section
There are two types of Move Edge/Move Vertex, and the shape is changed by moving it with the Line(2 Point) function.
The biggest advantage of changing the shape of a section through the Modify function is that it can be modified immediately without prior work.
Without setting the parameters in the past or organizing the coordinates of the vertices of the section to be transformed into Excel form
The shape change process proceeds only with Select and Move.
Also, when changing the section through the Modify function, the shape of the section that is changed through the Preview screen can be viewed.
It has the advantage of being able to check in advance
The Vertex Coordinate function is a method to change the shape by directly inputting the coordinates of the vertices that make up the shape of the section.
If the coordinates of the shape you want to change are organized in Excel format, you can copy/paste and adjust multiple vertices at once.
Figure 3. Vertex Coordinate
The coordinates of the shape you want to change are limited to the User Parameter or Modify function, or In the case of a form that can be implemented only by performing a number of tasks
(Ex. The direction of the vertex you want to move is different for each vertex, so batch operation is impossible)
Changing the section shape using vertex coordinates can be more efficient than other shape transformation methods.
