I'm have trouble getting this block to work, I've tried polar stretch all differect ways but cannot get it to work, I would be grateful for any ideas/suggestions
I'm tring to pivot everything at the base point and only stretch the end part.
It needs to be polar
Solved! Go to Solution.
Don't know if I understood it correctly but is it something like this you want?
Well, to exactly do what you said, the simplest way would be... I think...
Let me know if you really ment this.
Now I'am confused ^^, what kind of function do you want Lawson?
Beginning to think mine was abit out of line xD
Edit: This is way out of my line of work so I really don't have a clue of what it is meant to do
Hey Adam, I can't speak for him, but I think that he would ultimately want something in between both of our solutions. I gave him exactly what he had written, but as a former structural drafter, I can say that you would almost always want the turnbuckle to have the tensioner assembly centered. This proves to be a bit difficult when using a polar stretch parameter on multiple in-line objects. I tried adding an additional stretch action to the polar parameter using a .5 multiplier to center the adjuster, but that screws up the rotation. I had just as much trouble with trying a second polar stretch action to do this instead. Neither one rotated correctly. I'd love to see it done correctly.
I only did one side because it's all that is needed to show the function, thinking that it's easy to copy and remake it on the other side aswell. But I just realized that is probably not possible, the 1 blockproperty tablet per block restriction prevents you from using different angles on both sides. =/
Makes it pretty worthless.
Off the record, I totally forgot about the polar stretch action :X
I very seldom use it since I never really learned it in the beginning, and since all my block was done with normal stretch I kinda forgot about it, thanks for the reminder :X
I could probably have made it abit easier for myself if I had used the built-in rotation stretch =P
Never be embarrassed Adam - you've helped out a lot of us over the years! We all forget some of these ill documented things when we don't use them. I just picked this up because I've been working through something similar lately.
I thought I should keep at it and learn some things. I was able to create an auto-centering turnbuckle after all - a little thinking on how to aviod double rotating the end of the outer shaft and use of a construction line and a symitrical constraint and volia! Hope the OP (or someone else) can benefit from this.
a few tags to help others find the answer...
chained polar stretches
polar stretch and rotate
Ron, your first one is exactly what I was looking for
Thank you for your help, I'd be interested in how you got it to work, I've tried to recreat it but cannot
Yer welcome sir. It was good for me to work through the issues with the polar stretch. If you are wondering how to set up this kind of action, I used a polar parameter and turn off one grip, then added a polar strretch action. The polar stretch action is different than other stretch actions in that it prompts you for the crossing window, then the entities to be stretched, then a third prompt- Items to be rotated only. The secret is in what you include in the second prompt and what you include in the third prompt.
Hope that helps explain. If you found my work helpful, would you mind selecting "Accept as solution"? Thanks!
