Scaling uniformly using VCB
-
HI,
Sorry if this has been asked, but have just spent the last 1 1/2 hours looking for the answer, here, youtube,sketchucation etc.I think I saw somewhere someone asking of a tapered column could be drawn, 500mm at the base, 1000mm height and 400mm at the top.
I got to thinking,
Draw the circle at the bottom, 500mm
Push/pull to 1000mm
Scale the top 0.8 (or 80%) of the large circle (sorry percentage maths is a struggle for me thats why I chose easy numbers
)The question is: is it possible to click on the top of the column, select the Scale tool, and type in 0.8 to the VCB to get the finished taper?
If it can be done, how would one go about it, I have tried everything I know, which I admit is not a lot yet.
Thanks in advance

Phil,
Just start your scaling operation and then type the values (do npt click into the VCB).
Note that with the Shift key you can modify uniform / non uniform while with the Ctrl key the scale about opposite / scale about center options.
In this case you'd need a uniform scale about the center.
You can either type in the ratio (0.8 in this case) or the correct measurement (400mm) but followed by the mm otherwise it will become 400 times larger.
With the side grips it is also easy to snap to an inference point while with the corner grips it is not (or even impossible? I never managed to...)
Finally, I hope you don't mind me moving this thread for this tutorial forums are really for finished, "destilled" tutorials...

I don't mind you moving this thread, sorry I put it in the wrong section.
I have followed your advice, but, the top pf the column resizes off centre, how do I get it to resize concentric about the middle?
thanks again. -
By pressing down the Ctrl key while doing the operation. (You cannot enter anything into the VCB while pressing the key but right after you release it and enter the value and hit enter, it will jump there).

You learn something new every day! I've spent so much time trying to ctrl/center to the right value, now I know I don't have to do it manually, yeah!

Hi Philip, hi folks.
See attached SU file for ideas.
I used one of the side handles with the SHIFT key and the ALT key together to get a scale about the center AND a uniform scale along two axis at once.
That is on a Mac. On a PC you would use SHIFT and CTRL.

Hi Jean,
Thank you for the tutorial, but I must be missing something,
I made a copy of the profile on sheet one, then followed your directions,
But (and this is where I am missing something) Every time I let go of the Shift and CTRL keys (PC) tp type in the dimension, the red scale handle that is on the center disappears to the outside and when I type in the figures the model scales only on one axis.
What am I doing wrong?
thanks

Philip,
Just keep the Shift+Ctrl buttons pressed when starting the scale operation then release everything, type and hit enter.
Like with most of the actions in SU, you can enter the values into the VCB immediately after the operation (in this case scaling) and not only during the operation. -

It started to make sense, and it also worked, thanks for taking the time

Sorry to dig up this old one...but is it possible to do a 'Copy+ scale uniform around center'?
Basically I need to offset an object to the centerpoint while scaling the coby down.
A box in a box so to speak....(in my case no box but car windows I need to make double glazed)Is that possible?
-
No, with the scale tool you cannot perform copying (like the linear and radial arrays with the Ctrl^Move or Rotate tools).
I know what you mean because I have played around with boat hulls and when I wanted to make thickness to the tediously created mesh, I obviously didn't want to stitch all those beziers together again.
My workaround in this case usually is that I make a Ctrl+Move copy somewhere out, scale the new copy (carefully choosing which direction, about opposite point or center etc. I scale it) and then move it back.
Now however there is this great script "Joint Push Pull" by Fredo that can help you (although I succeeded to screw it up with a hull but that was most probably my fault
)I have made this shield (and also its edges even thicker) with this script. On that path I could not have used the Follow me tool so finely. I guess if your glass is not too curvy, it must work pretty well.

You can do Copy, then Paste in Place and scale the new copy - I think that has the same effect.

True but make sure you group the geometry prior to it since otherwise it will simply merge with the original.

Thanks Greyhead and Gaeius for the tips.
the simple copy and 'paste in place method' worked like a charm.
