Applying Parametric Constraints to Dynamic Blocks

AutoCAD block libraries can quickly become unwieldy due in part to the need to capture multiple options of what’s effectively the same item. A common example of this is a table that is offered in 6 ft, 8 ft, and 10 ft varieties. Each of these requires it’s own block simply because of the differing lengths. To help combat this, AutoCAD has long had the ability to …

Creating & Using Blocks With Multiple Insertion Points

As you may have noticed, there hasn’t been much activity here on The CAD Geek since AU.  The reason for that is quite simply I have been on vacation since December 13.  Today however was the end of my three-week break from the office, and gasp; AutoCAD.  As much as I love to play with and explore the depths of AutoCAD, I must say my vacation was a much needed break from CAD.

But now that I have returned to the office and the holidays are behind us, I shall also return to this, my humble corner of the blogosphere.  I must admit, after taking a 3-week break from AutoCAD it was hard to think up a blog topic, but I remembered a post from August titled “Dynamically Aligning Your Blocks”.  It was with that post I realized how few posts I had about the most versatile  Dynamic Blocks.

It’s a fundamental law of AutoCAD Blocks, blocks shall have an insertion point.  And frankly, this is a good thing.  Sure, AutoCAD needs to know this location so it can remember where you placed the block, but face it – you need this insertion point too.  When drawing blocks we’re taught to place this insertion point in a meaningful location.  Maybe it’s the face of a curb in a civil plan, or a wall in an architectural plan.

Dynamically Aligning Your Blocks

I was just looking back upon some of the topics I have covered in my 100+ posts here at The CAD Geek.  Naturally I have covered a lot of topics, but one topic I was embarrassed to see virtually unexplored here was Dynamic Blocks. Over the last several years I must say I have become quite a fan of Dynamic Blocks.  In fact it seems my name has become synonymous with Dynamic Blocks here at Timmons.  So there you have it, today I am breaking my silence on Dynamic Blocks (not that it was intentional).

Especially as I was getting started with Dynamic Blocks, I personally found using the pre-build Parameter Sets easier than manually assembling Parameters and Actions myself.  Consequently it wasn’t until I began venturing into the more advanced functionality of Dynamic Blocks that I discovered a little Parameter that has since become one of my favorites – the Alignment Parameter.
