Introduction

Creating a dynamic CIM with a repetitive shape is similar to creating one with a continuous shape, but there are some things one should be aware of. Following is a guide over how to create a Toothed anchor channel and some explanations of the things to be aware of. If one needs a more detailed guide over how to create a dynamic CIM, start with this article. 

Create a dynamic CIM - repetitive shape

Sart with creating a solid model and a 3D wireframe model. Make sure that the models are drawn in the right direction according to the dynamic properties. It is not necessary to draw the 3D wireframe model. Using it or not depends on how the dynamic CIM will be presented in the project.

Make two copies of the 3D wireframe model and rotate them with AutoCAD command "3DROTATE" so that the models are seen from top, front and right, when looking at them from the top (see  Figure 1). 

Figure 1: Models of the Toothed anchor channel, drawn in the right direction. The wireframe models are rotated correctly. 

Define the Dynamic CIM

Continue with creating a new definition of a dynamic CIM, and start with defining the 3D solid. A more explained guide of this can be found here. 

Figure 2: Defining level of detail 4 and 2. 

When choosing the insertion point, one needs to think about how the dynamic CIM will be used. This Toothed anchor channel will be inserted in on a surface of an element. Because of that, the insertion point will be at the top of the model. 

When defining the 3rd level of detail, one needs to select the right oriented model for each view as can be seen in Figure 3.

Modification of the block files is done at the same way as for a dynamic CIM with a continuous shape.  

Now, the dynamic CIM is finished and ready to be used. 

Applying Dynamic CIM - repetitive shape

Using the dynamic CIM in an element is done at the same way as any dynamic CIM. This article will provide a guide over a special case for applying the dynamic CIM. 

The special case is when one needs to insert a dynamic CIM on a sloping surface, for example, a sloped beam with. If the element would not have a sloping top, one would just draw the dynamic CIM parallel to the top. In the case of a sloping top, one should draw the dynamic CIM parallel to either front or back, and then add a distance from side and a rotation.
