Dynamic Block help

All links need approval until you reach 10 posts, but you can attach images directly in CADTutor, no link needed and no waiting for approval, you can attach lots of things directly to CADTutor, just click Go Advanced then Manage Attachments.

Your image is not awaiting approval though, I can't see it because third party image hosting sites are blocked at my work.

Duly noted, I appreciate the explanation. Makes enough sense for me

I'll try and explain. Let me know if any of this is unclear.

• You need a single Distance parameter. You can attach multiple stretch actions to this in order to properly control the location of your objects. This is what allows you to 'slide' in between the two visibility states. As your distance moves past 18" the lookup table toggles the visibility state according to the rules that you have set. I used two stretch actions for the center aligned setup in order to keep your point object in the right location. Only one stretch action was needed for the end aligned setup.
• You need a double lookup set, not a single lookup set. To do this right click and copy the Lookup Set and then paste it back in and rename it. Then right click to edit it's properties and click on the add actions button and add another lookup.
• Then you can assign the Distance parameter to one lookup and the visibility parameter to the other. You tie them together with a random tag (I used 's' and 'l'), that is the same in both lookups.

You will want BACTIONBARMODE set to '0' through all this in order to properly work with double lookups.

I have finished your block but I thought I'd let you try before posting it.

Thanks. I will work with these notes and comment after I have tried to complete it. I do want to try and figure this out, so thanks for not posting it yet.

I think I got it. Thanks iconeo. My problem was the BACTIONBARMODE was set to 1. I could never see the double lookups. Once I changed that to 0, holy crap there was a literal cloud of lookups from the sets I had previously inserted. Had to delete every one and start over. But it turned out good I think.

Thanks for giving me a chance to learn it.

See attached.

Glad to hear it. Mastering double lookups adds a whole new dimension to dynamic blocks.

This is very minor but using [0",1'-6") means that at 18" it will toggle to 'end aligned'. [0",1'-6"] and (1'-6",) would better suit your purposes.

Thanks.

I agree. I already have many uses in mind to work on. Thank you for all the help and pointers.

Minor changes are good. It will get me on the correct path to do it best for how CAD interprets it. I will make those changes.

Thank you again.

My next task is to tackle a dynamic block similar in fashion, but a lot more complicated. I may be back with questions, but the premise is this...

1) distance stretch.
2) hole 3" from each end
3) hole centered between each end hole when distance reaches 24" to 32"
4) at 32" a hole is entered 16" from each end hole
5) then repeat from step 3 from those two newest holes.

Hope that makes sense. Any pointers to begin would be appreciated. How many lookups would I be looking at here? I'm thinking visibility states would not be good in this regards.

If I understand you correctly I think you would only need to add one more visibility state. Your lookups will handle all of the toggling of states but simply added more use cases. Just be sure to have a unique identifier for each visibility state that the lookup can tie into.
