How to Make a Double Lookup

Libbya — Mon, 24 Aug 2015 21:20:28 GMT

Double lookups are so darn useful and slightly tricky to make so I figured I'd make a screencast in a dedicated thread that shows exactly how to make one and how to select each of the tables.

Libbya, thank you so much for posting this!! I was a bit lost from our previous thread as I've not used lookups before but this is awesome 🙂

Thanks,

cmaso

I didn't realize you had posted that. Still, it's nice to have the advanced options in the forum post, e.g. to be able to make it go fullscreen. I also intentionally moved extra-slowly so folks can see what actions are required. The commands at the bottom are also a nice addition although it is incorrect. Where it says 'add basepoint' is actually adding a double lookup and single lookup.

As shown in the screencast, in order to see both of the lookup tables that are associated with the double lookup, it is necessary to have the system variable BACTIONBARMODE=0. when BACTIONBARMODE equals zero it also makes it possible to add an action to another action's selection set. This is particularly useful for getting everything working correctly with flips. I usually keep that variable set to 0 but sometimes it is useful to switch it to 1 when I want to select all linwork and parameters, but not any actions. I got tired of typing out the whole name so I made this simple LISP that defines the command 'BA' which will toggle the BACTIONBARMODE system variable between 0 and 1.

(defun c:BA
  ( / )
  (if (= (getvar "bactionbarmode") 1)
	(setvar "bactionbarmode" 0)
	(setvar "bactionbarmode" 1))
  (princ)
  )

Mechanical 2020 does not have an option to add a second lookup. Am I doing something wrong?

You are trying to create a tool from the lookup action instead of the lookup parameter.

@Libbya That would do it, thanks!

why I don't have those 2 lightning thing, what I got after inserting double lookup is a small box just like this.

Re: How to Make a Double Lookup

I took the time in the initial screencast to specifically address that. You might want to watch it again.

which part of the video? first you copy lookup (parameters), pasted it, move it on top of basepoint then change its properties and used it. which part did I miss?

Re: How to Make a Double Lookup

Libbya — Tue, 21 Feb 2023 12:45:25 GMT

The part right after that in the video. You also didn't bother to read the posts. You are taking spoon-feeding to a whole new level.

Re: How to Make a Double Lookup

JoseMandirigma — Thu, 23 Feb 2023 05:40:18 GMT

I understand now. Additionally, you mentioned to watch it again based on your initial response. However, in the video, it didn't demonstrate how to change the variable, and it was only discussed in a post which I didn't bother to read. That was my mistake.

That is not true. At 1:54 in the video I start typing it in and the value is changed to 1 at ~2:08 in order to show the alternate display of the tables. I type it in again and change it back to 0 at the end of the video.

JoseMandirigma — Sun, 26 Feb 2023 11:54:37 GMT

Oh darn, my bad. How did I miss that? I rewatched the entire video and didn't see you change the variable before. Sorry about that, and thank you.

Is it possible to copy visibility states? @Libbya

Re: How to Make a Double Lookup

h_s_walker — Fri, 28 Jul 2023 10:36:40 GMT

@JackTryMC No you cannot copy visibility states between blocks. You need to create them again in the new block.

Or save the old block as the new block. I would also suggest starting a new thread with your exact problem

Yeah, start a new thread. Your question doesn't really have anything to do with the thread topic.

I found a similar way to do 2 lookups, but with one Lookup. You can add multiple parameters to a single lookup action. This also provides the ability to do asymmetrical lookups. For example, in the attached block, I have Width (X) and Height (Y) stretch parameters. With 2 lookups, selecting a value changes the height and width using the same value, i.e. a square. But with the lookup in this sample, I can implement a table with x and y of different values.
