Stretchable Array

lrodgersL3G4V — Fri, 18 Apr 2025 15:42:50 GMT

Can you have a stretchable array? I want to have a rebar end array to every 2" but also every foot.

Does that make sense. I want to be able to section thru the rebar in a concrete slab every foot (multiple rebar), but also be able to put it in a thickened slab or bond beam at 4 to 6" apart for only 2 of them. Right now I have it with a 1' array.

Would you please post an example of the expected result, so we can see your intention.

In the jpg below I have the top rebar arraying at 12". And I'd like to also be able to array it at 4" like the bottom rebar.

I must confess that I still don't understand your intention.

Therefore, I'm attaching a first draft as a basis for discussion.

How about something like this:

those are 2 separate arrays on 2 rebars correct? I was wondering if it could be done with 2 arrays on the same rebar?

Or if you could select the array spacing before you actually array it.

My attempt does use two separate arrays, but they're within the same block. A single bar diameter selection sets the bar size for both arrays. A visibility state selection chooses if there is just one row of bars or two. When there are two you get the option of selecting the vertical separation between the two rows.

Neither of these solutions is what I was looking for.

What I want is to select the rebar and then stretch it to 12" spacing and then select a second instance of the same block and be able to stretch it at 2" spacing.

Based on Mark's suggestion this next rough attempt.

That is closer to what I need. I would need visibility states for 4" and 6" spacing. Now I can not have visibility states for the different sizes of rebar. Unless a double lookup table would work for that?

Here's a second attempt. This one uses the ARRAYPATH to do the array of the bar(s). There are three of these, one for each size bar. The spacing of the bars is a User Parameter. (types in to the spacing value of the arraypath's properties) There is also a Block Properties table that supplies possible values to the spacing user parameter.

I have it working with 12 visibility states. But now I'm wondering if it can be done so its easier for the user if we used a double look up?

perhaps using a block property table?

Or, if you urgently want to use double lookup, try this.
