Hi all,

I've done very little with dynamic blocks, but made a few for adjusting stock sizes of parts I have.

I've been trying to expand that by looking at making a dynamic block to change shapes, for example a welding call out. Fillet, bevel and so on.
I've succesfully made one but it was lengthy and found that I may be able to use 'lookup' instead. Watching over some tutorials (granted for autocad) I'm not sure it's possible. They seem to right click the lookup parameter and make it a 'double lookup' which isn't a option for us here.
So I'm basically after some help/guidance. It it possible to use lookup to show and hide various shapes?

Thanks in advance

Yes, it's definitely possible to use lookups to show and hide various shapes within a dynamic block in AutoCAD.
Here's a general approach:
Create Basic Shapes: Start by creating the different shapes you want to display (e.g., fillet, bevel, etc.) as individual blocks.
Create Dynamic Block: Create a new dynamic block and add these individual shapes as block references.
Create Lookup Parameters: Create lookup parameters that will control which shape is visible. For example, you could create a lookup parameter called "Type" with values like "Fillet," "Bevel," and "None." space waves
Assign Visibility Conditions: Use visibility conditions to associate each shape with the corresponding lookup parameter value. This will ensure that the correct shape is displayed based on the selected lookup value.

Thanks for the reply. I must be doing something wrong. It's the last stage I just can't get my head round it!

Thanks this is exactly the information I was looking for.

In IntellicadMS, you can use lookup parameters or visibility states to create dynamic blocks that toggle between shapes like welding callouts.

While IntelliCAD may not support the exact same features as AutoCAD, you can still use lookup parameters to create a simplified version of what you're aiming for. The lookup parameter allows you to define multiple states for your block, which can be assigned to different shapes.

Absolutely, you're on the right track—and yes, you can use the Lookup parameter in dynamic blocks to show and hide various shapes, though it does come with a few limitations, especially depending on the AutoCAD version or vertical (like LT vs full AutoCAD) you're using.

It sounds like a printer scaling issue, not a drawing problem. Check that your print settings are set to "Actual Size" or 100% scale, and disable any “fit to page” options. Also, verify your paper size and printer driver settings. IntelliCAD likely isn't the issue if both machines show the same result.
