Hello all.
There is something I am just not gettin with regards to using grips to edit a cylinder. Lets say, I, from the righ side, draw a cylinder of some diameter and some height. I then change the view to top. What you have, in appearance is a rectangle. If you highlight it, and you then see the grips that are associated with a cylinder. If I grab the stretch one, and pull it left or right, you see a line go up and down and it will not stretch the cylinder. Now, if I change the view to isometric, I can stretch the cylinder. Why am I not able to stretch it in the top view?
Thanks!

check your uscfollow variable and try again....
this is one of my favorite LAME defaults....it's a 3d application WHY would one NOT want the Coordinate system to change to match the view is beyond my ability to ever imagine...... :ugly:
-
very odd...
I just ran a test
set view to left side draw a cylinder
switch to top view
stretch the cylinder...longer or shorter no problem
switch back to left view
stretch cylinder (diameter) in or out
all works just fine....
using the grips...not the command

uh... everyone who models in a non-orthographic view, for one.
-
uh huh, but whould'nt you want the ucs to go along with you as you changed into those non othographic views?
I know I sure do...

hell no.
I like looking at a roughly isometric perspective when modeling on an XY plane, so I can see the Z elevation... I wouldn't want it the UCS to suddenly change to orient the XY to be normal to my screen at all times... Unless I'm misreading what you're saying, I think that's a terrible idea.

and with that you point out autocad's biggest weakness:
the inability to have multiple REAL TIME active viewports to do ones 3d modeling with....as in Microstation and 3d viz and Max....
it makes working in 3d so much easier....

I dunno man, I've done my fair share of modeling in Rhino, Max, and a few misc other programs in minor amounts... done a great deal of modeling in Inventor and Solidworks as well...
I find the single viewport quite capable... the option to have more would please many people I'm sure...
I'm mainly just trying to make the point that I feel you're EXCEPTIONALLY overstating the situation, and that your claims of it being a FAULT or being a "lame default" are simply... way off base.
Also, you do realize you -can- have multiple views, simoultaneously in modelspace, though, right?
-
yes one can have multiple views, however they are not ALL active at any given momment, so one can not select an item in say the iso view and then use an objects snap point from the left side view.....
And I don't no that I am overstating the case. As one of the most common questions new users ask is.
Why If I changed from one veiw to another and a draw a line do I only see a point? Or some variation thereof.
Reason being the ucsfollow default in a; 3D application being set to OFF, seems to be way wrong.
-
if they changed UCSFollow's default, the first thing I would do is add another line to my startup lsp to switch it back...
I can't think of any reason the UCS should be normal to your computer screen, no context I've ever had would make me think that would be a positive change... when working in 3D, you normally -want- to see 3 axes' directions, not 2.... then you're working in 2D.

Barry part of this could also be the following:
http://usa.autodesk.com/adsk/servlet/ps/item?siteID=123112&id=8048136&linkID=9240617 (http://usa.autodesk.com/adsk/servlet/ps/item?siteID=123112&id=8048136&linkID=9240617)
When you tried to use the PRESSPULL command on a closed 2D object that is not in the current user coordinate system (UCS), you were not able to select the shape you wanted and initiate the command. On the command line, you saw the following message:
0 loops extracted.
0 Regions created.
Solution
The PRESSPULL command will not work on 2D shapes that are outside of the current UCS. To use the PRESSPULL command on these shapes, you must set the current UCS to align with the object. Follow these steps:
At the command prompt, enter UCS.
Enter OB or OBJECT.
Select the object.
Repeat the PRESSPULL command.
A good example of having the UCS follow option set to on, as this would most likely eliminate this type error.

Didn't fix my issue... but it definitely made it weird.... and annoying. haha.

Not sure what I am doing wrong then... or what settings I have not right for what I want. Longer and shorter is what I want.

Not having that problem. Thanks all the same though.

It was Ortho being on. Can't have that on. Geez. :roll:
