Using multiple insertion points in dynamic blocks

I tried to explain about dynamic blocks and their properties in my previous articles (found in “Dynamic Blocks e-book“). In this article, I will explain how to create more than one different insertion points for a block.

Fig. 1

We know that each PROPERTY and ACTION that you insert in a dynamic block creates a GRIP. In addition to this, we also know that when dynamic blocks are inserted in a drawing, if you press CTRL button, then dynamic blocks have the property of changing the insertion point depending on these parameter points. Thus, depending on these features, we can create multiple insertion points by creating POINT parameters for our dynamic block as much as we want. In order to prepare the dynamic block in our example, I have explained how to enter block editor and create a dynamic block in my previous articles. Now, create a 160×140 L-shaped table in block editor as shown in Fig.1. And add POINT parameters at the corner points of this drawing as shown in Fig. 2.

Fig. 2

In order for our block to be a valid DYNAMIC BLOCK, at least one of the parameters must be associated with an ACTION. In order to do this, associate the POS1 point with the simplest action MOVE. Its functionality is not important at this stage. Depending up on your demands; if you have parameters at different positions which you don’t want to use as insertion point, then you can edit the operation sequence and status of them by using BCYCLEORDER command.

Command : BCYCLEORDER

Fig. 3

You can edit which points will be used and in which sequence they will be used by using command window as shown in Fig. s3. After completing all of the settings, then close the block editor and try to insert the new created dynamic block in modelspace:

Command : INSERT
Specify insertion point or [Basepoint/Scale/X/Y/Z/Rotate]:

At this stage, every time we press CTRL button, insertion point will change between 4 points that are shown in Fig. 2 (Fig. 4).
