SCALE Command Not Working

[Anonymous]

I am trying to attach a google earth image and scale it. 

Using the Scale command, I don't get accurate results. Here's how I'm trying to do it. 

Attach the jpg

Start the scale command

Select the attached jpg and hit ENTER

Click the base point (one end of the scale bar in the jpg)

Select R for Reference and hit ENTER

Specify reference length (200) and hit ENTER

Then it asks me to specify a new length ... I must be messing up the sequence. What am I doing wrong?

Thanks.

You will need to know a distance of something on the map, like the length of a building.  Then for reference you point to the opposite ends of the building and then type in the actual distance.

Select R for Reference and hit ENTER

Specify reference length (200) and hit ENTER

R for ref

pick end point and the other end point then the distance.

Right. I have a distance. The image has a scale bar in it, so I know it's 200 feet. 

I'm using the start of the scale bar as my reference point.

Hi,

you might try command _ALIGN, that gives you the choice to select transformation points and then it rotates AND scales the objects accordingly to the reference points.

 I'm also unclear about what is meant by "base point". How do I determine that?

Scale bar is on the image so you have to draw a line on top of it so osnap can use it.

Select the line as reference.

Hi,

Create a new drawing, just one rectangle, now test command _SCALE and try different corners of that rectangle as basepoint and see how (into which direction) the size then changes 😉

Follow along with this. I'm scaling the cyan rectangle to the corner of the green line. Not quite on top of the red rectangle.

From another post but same idea.
