Stretch command

[DODGE]

Hi Guys
It's one of those days today.:cry:
I have just been trying the stretch command. I have never used this before today so thought it might be good to learn a bit more.
I have managed to stretch items ok but not accurately. I tried to stretch a simple rectangle 200mm to the right.
I hit the stretch command and make my selection, hit enter then type in 200mm enter, and it goes right off the screen.:shock:
If I drag the rectangle it's fine but not accurate.
This might be another dumb question, but hey you gotta ask.

To stretch your rectangle to the right 200mm (assuming your units are mm)
STRETCH command. Select using Crossing of the right side of the rectangle. Type in @200,0 and it should stretch fine.:)

DODGE....

After you make you selection, hit ENTER and then type @200<90.......where 200 is your distance, and 90 is the bearing (angle) direction you want to stretch in.

Use CROSSING to select for stretching, and if you cross the end point of any entity, you will have to deselect that entity before you hit ENTER.

See if that works.....:)

Cheers

[DODGE]

Yep tried both these.
This is weird.
After I use crossing to select I type@200<90 and then enter.
The rectangle shoots off to the right at an angle of 12.3º.
I chucked a dimension on it and it's 41m long????
What the?

I think you had better check your drawing units (UNITS) and check your direction control (part of the drawing units dialogue box).

Also...are you drawing in metres or millimetres? Also check your UCS is set to world. :)

EDIT.....also, you don't need to chuck a dimension on it to see how long it is......use the command DIST.

DODGE....

Here's a lisp routine to return a distance and bearing......

Hi Al
I'm drawing in millimetres.
How do I make sure UCS is set to world?
D

[Alan Cullen]

Type UCS....you'll get a lot of options on the command line (it should default to WORLD...if it doesn't, just type W......try all that and get back to me.

[DODGE]

Thats all fine Al
It's set to world
D

[Alan Cullen]

So.....are you still having stretch problems......or is everything now as it should be ? :)

[DODGE]

Yep Al
It's still doing the same, I can't understand it.
Looks like I will be giving the Autocad bible a bashing tonight.

[mdbdesign]

I try on 2002, 2005, 2007 and v10 work OK even I change UCS???!!!

[Alan Cullen]

DODGE.....post that drawing up and I'll have a look at it......probably quicker than trying to sort it out by going back and forth here...

[DODGE]

Thanks Al
But I don't really have a drawing I was just playing
around with a rectangle trying to learn stuff while
I had a spare hour.

[Alan Cullen]

Hmmmm....it sounds like you have a problem with your setup in your template.

Check your drawing units again, and set them to the following......

Drawing Units
Length
Type.....decimal
precision....1
Angle
Type.....Deg/Min/Sec
Precision.....0d00'00"
Clockwise.....tick
Insertion Scale.....unitless
Direction Control
Base angle....North....tick

I know architects use East as 0 degrees and measure angles counter clockwise, however there is no reason why you shouldn't use the cartisian system.....

North......0 degrees
East.......90 degrees
South......180 degrees
West........270 degrees

Apart from that I really don't know that I can help you without having a look at your drawing template.

Hi
I have been encountering the same problem as Dodge (only on the STRETCH command though).
For instant a sample 500x500 polyline square I want to stretch it to 500x800 and extend to the right. (I know I can simply draw it but here is for exercise).
1. selected objects by crossing window.
2. specifed bottom left as base point
3. specify second point:
If I pick the bottom left again, press enter – nothing changed
If I pick a new point. Doesn’t matter where, the whole object will move to the second picked point without change of shape.
Please help.

The secret to stretching is how you select. You must use the crossing window, and any lines wholly in the window will be moved, and any lines half in the window will stretch.

When you have selected correctly, and have ORTHO on, then move the mouse in the direction you want to stretch, and enter the distance at the command line. :D

Yeah this will work, i do it the same way except using polar instead of ortho
