Stretch and flip

[Anonymous]

Hey guys,

I am trying to creat a dynamic block that stretches evenly on both sides and also has a flip command. I can't seem to get these commands to work together properly. I got the block to stretch correctly but if I flip the block more than once it doubles in size.  Attached is my file I am trying to use. Can anyone help me? I need to be able to flip the block in any direction and stretch both direction simultaneously.

Hi Hwalker,

Thanks for the reply, however if I simply change it to midpoint, the line would go in a different angle(please have a look at the attached file)

Also can you please explain me how the scale action is working in this block.

What are you using the scale action for? If you want to keep the dashed line at the same position where it is now, just add it to stretch 3.

The reason why it's "moving" is because you've added it to the SCALE. Scale affects objects in both the X and Y directions.

Hi Libbya,

The attached block works fine but once it's flip the hatch needs to stretch. Can you please advise how to make that happen.

@ndikesh what about centering the block and then stretching both sides???? you can then use a midpoint snap where the current base point is to move into position if so desired!!!

Here's how I would create that behavior.  See screencast:

@Libbya , you are awesome. Thanks a lot.

Dear @Libbya,

I saw you're expert on this Stretch-Flip problem/issue/challenge thing.
I tried multiple approaches (with phantom distance; with point) described in this threat and nothing worked for me. Is it possible, to look into attached files (both variants) and see what I'm missing and doing wrong? 

Thanks.

P.S.: Of course anybody else can help. 😉

@MRupnik You need to flip the appropriate stretch/move actions.  Flipping an action with an angle offset flips the angle offset EXCEPT if the angle offset is 0 or 180 it remains unchanged.  Because of this you need to get a little fancy.  With your main linear parameter, stretch a chained parameter with an angle offset that ISN'T 0 or 180.  Then have that chained parameter use the complementary angle offset to stretch the objects you want stretched.   You then need to flip ONE of the stretch actions (either the one stretching the chained parameter OR the one associated with the chained parameter).

You had multiple issues in both of the blocks.  I don't have time to explain all of them.  Here are your two blocks back functioning properly.  Hope that helps.

Wow @Libbya, that was fast. And great, thank you.
So, from what I can see, my basic problem was, that my actions were 0 or 180°and thus flip didn't flip it? 
Again, this was really helpful and already in use.
