[Plugin] Selection Memory

[thomthom]

Overview
Response to this thread: http://forums.sketchucation.com/viewtopic.php?f=15%26amp;t=42390
Will let the user cycle through the five last selection sets. Useful when you for instance accidentally deselects a carefully crafted selection.

Important!
This plugin has not been tested under OSX! It is not known how it will behave under SketchUp OSX where one process can have multiple models open. Unpredictable behaviour will most likely occur - possibly bugsplats.

Modification
To modify the number of saved sets, modify this constant:
SELECTION_STACK_SIZE = 5
I recommend you do not change this to a too large number.

Access
Edit > Cycle Previous Selections

Features

• Cycle Previous Selections
  Cycles through the last 5 selection sets.

Requirements

• SketchUp 8 or newer - ( Other versions untested )
• Might work with older version. Just test for yourself. Either it works or it doesn't.

Nice tool

Works like a charm

Thanks, thomthom:
Tested in Sketchup 7, also. Worked on first try.

When you double click - two selections sets are made. One for the first click on the face - and one on the second click when edges are selected.
If you deselect after a doubleclick you need to cycle two times to restore the selection with both borders. It is a bit counter-intuitive some times like that.

Basically how it works:
Every times you change the selection - the selection set is stored in the selection stack.
Cycle selection advances the internal index and fetches the selection set associated with that index.

The plugin is a bit rough around the edges like that.

Thanks!
It seems not working with edges with the last selection. I mean select a rectangle with a double click-->deselect-->"cycle previous selection" and only the face is selected. But if you've made another selection and go back to the initial selection then it works.
SU pro 7.1

Oh, I see. Thanks again.

[massimo]

Another thing: it seems not working with selection window from left to right. Is that normal?
Also not working with artisan's select brush.

Seems to work here. SU8?
As far as I've seen - it work with any selection.

Not sure how Artisan's selection brush works. If it continuously updates the selection then it might cause unexpected behaviour - as the stack will the flushed very quickly. It works by using SketchUp's selection observer...

[numerobis]

WOW! This sounds great! I have to test it...
thanks!!!

[massimo]

I have SU 7.1 and can confirm that here not works with left-->right selection while it works with right-->left selection.

Just tried it myself - I see no problems with Left to Right as oppose to Right to Left...

Are you able to make a short video of what you see?

[thomthom]

Ah - it's something to do with how it retrieves back the previous selections. What you are experiencing is probably that it retrieves an earlier selection set. Might be empty.

There is five slots of selection sets - always - even when you start a fresh model. Keep cycle through and it will come back. I'll have a look at it. But this plugin isn't on top of my priority list.

[massimo]

Ehm...I'm afraid not. Anyway this is what i do:

• Draw a simple rectangle for example;
• Select all (edges and face) with a left-->right window.
• click anywhere to deselect;
• run "cycle previous selection" and nothing happens.
  EDIT it's not working with right-->left selection either.

Ah! That's maybe the reason. Thought that with a fresh model the "memory" would have been deleted.

[thomthom]

Well, it does - but there's a pre-reserved set of slots regardless. Which then are "filled" as you use it.

The plugin was written very quickly so unfortunately it has this behaviour which is illogical from a user point of view.

[massimo]

Ok, no problem.

[andybot]

Thanks Thomthom
works as expected for me!

[thomthom]

Version 1.0.1
Did a quick tweak to it. I believe it should retrieve the previous selection more predictably now.

[massimo]

Now it seems to work just fine.
