Two Rotation Issues

[kkline116]

Hello all... new to the forum, but long time lurker.

 

I'm having two challenges with the attached block. Dumper.dwg

 

1) I want the red box to go around the white box to the 3 location indicated with numbers, but NOT where the red X is (that's the rest of the machine, and the dumper can't go there).

 

2) Even where I *can* get the red box to rotate to, it bothers me that the little blue rotation dot moves when you use it to rotate. Why can't I get that to stay in the middle of the white box?

 

It starts off in the center:

 

 

Rotate, and it moves off center:

 

 

Any help would be greatly appreciated!

 

And I'll just take this opportunity to say thanks for all the other help on all the other threads. I've never even had to post because I was always able to get my questioned answered, but this one has me stumped and a search didn't return any results.

Okay, I figured out how to get it to rotate to just those 3 positions:

 

I just set the properties of the parameters to the following:

 

 

But I still can't get the rotation grip to stay in the middle of the machine:

 

 

Any ideas?

 

EDIT: What's really weird is that the dot moves to wherever your second click is. So, if you pick the rotation grip, and move your cursor outside the box, it moves the grip to that 2nd point... but then it keeps it there for all subsequent rotations.

 

 

Here's the updated drawing: Dumper 2.dwg

I think the problem is trying to get the rotation grip in it's own centre. I changed it slightly so that the base point is centred but the radius is only .0001, so at least visually it stays in the middle, I used a set list of angles which is another method.

Yep, that worked!

 

Thanks very much Steven!

Okay, so that worked in your block, but now I can't seem to get it to work in the rest of the blocks that I'm trying to make. And since I can't copy and paste a parameter, did you do anything else to make it work?

 

I took the properties of what you did and matched them exactly, but mine still moves.

 

For instance, take the attached drawing and compare the properties to the Dumper 2 you did. I made everything match exactly (that I can see), but my rotate grip still moves to wherever you click the 2nd time.

 

Dumper 3.dwg

 

I need to make about 10 of these things (different sizes, shapes, etc.), and if making the properties match doesn't fix it, I'm not sure what else to do.

It has me puzzled, I can find no difference between the two parameters (yours and mine) but if I delete the one you have done and redo it, then it works fine. How are you creating the parameter and action, do you use the block authoring palette?

[kkline116]

Yep. I open the block in block editor. Click on the Rotatation parameter, pick the midpoint of the diagnol line, move the cursor until the parameter looks like this:

 

 

Left click, select the "! box", select the pieces I want rotated, then make the properties match yours, and it still moves.

 

What's really throwing me is that the grip locks into place after the first movement... that's just weird.

Okay, I figured it out... I don't know why, but this is how I fixed it...

 

When you first put in the parameter, and you're setting the "BPARAMETER", the first dotted circle, pictured here:

 

 

You can't just hit "zero" because it tells you it's an invalid 2D point. So I just zoomed as far is as I could and made that circle as small as I could so that my Dynamic Input read zero inches, clicked, then zoomed out and set the label wherever, then set up the list of angels I wanted and now it works.

 

So it's something to do with that first circle (BPARAMETER). Apparently, if I set it with a distance (I just always clicked somewhere, but was never sure what that did), but if I did that, it allowed it to move. Now it doesn't.

 

I don't know... but whatever... it's working now.

[steven-g]

Thats the difference then. I set the radius to .0001 by typing that value in when prompted for the BPARAMETER.
