Dynamic blocks are a unique way to draw up models and edit them without actually having to affect the drawings. They are useful in very specific situations (often measurement related) and in short, they can put shapes into place that can be edited and moved around with ease. For this exercise, we were asked to create dynamic blocks on 3 different objects showing off the different types and uses of dynamic blocks. To start off, I decided that a table would be an easy object to do work on so drew out an extremely basic table model.
I then used the “create” button under the blocks ribbon to create a block out of the table.
After this, I filled in all the details on the “block definition” window. I made sure to change the title of the block as well as picking out the base point, ensuring all objects were selected and ticking to open up the model in block editor.
Next, I went to the parameter tab and selected “linear” then selected the top line of the table that would be stretching.
I then went to the actions tab and selected stretch.
After this I applied it into the linear parameter on both ends so that the table could extend either way.
Finally, I tested the block and now whenever I click on it in the model space, I can edit the length of the entire table.
The next block I decided to make dynamic was a chair block that I took from the “floor plan sample” file saved on our AutoCAD.
I then opened up the block editor and used the rotation parameter to select the area of rotation that the chair can fulfil.
After that, I applied the rotation action.
With this all being done, the model space now allows me to rotate the chair as much as I need to on that certain parameter.
The final block I decided to do work on was the sofa block that I also took from the floor plan sample we were given.
As before, I opened it up on the block editor and similar to that of the stretch tool I used on the table before, I added in the linear parameter.
Finally, I applied the scale action to the linear parameter and the model is now completely available to up or downsize in the model area.
