How to resize an object while keeping its aspect ration

[emx]

What would be the correct way to resize an object while keeping the ratio the same?

 

I'm having a not too simple shape and would like to resize it. On other software (I'm thinking e.g. Visio), you would select the entire object and then resize by sliding one of the selection's corners. This would increase the size of the object while keeping the same ratio. For example a 4x2 rectangle would be resized to 12x6.

 

In my current AutoCAD project, I need to increase the length of an object (e.g. from 800 to 850) but the ratio of all its other dimensions should be kept proportionally the same.

 

Thanks for any hint!

Selecting all objects that compose your project and using the command SCALE will do the job.

When the program ask you to select a base point choose a a start point of the length that should change from 800 to 850 (you could choose another poine but that's the way I use to do) and then when the program ask you to insert a scale factor or a reference type R, enter, choose start point and end point of the length and then type in 850 as a new value. This will scale all your project by the same factor. Just a note: dimensions text will not be scaled.

Another way is to make a block of all your project and then scale it.

 

Hope this will help you to sort things out

Yes, this is exactly what I was looking for. Thanks!

You are welcome. Glad I could help.

I think we may have covered it already, but it's best to check we have all the keywords in there

while in scale mode after you defined the basepoint you could type in "850/800" as a scale factor...this will only work with whole number tho...

Is it possible to change the dimension for one direction but leaving it unchanged for the other?

For example, 400x400 changed to 600x400.

Try making a block of your object. Then, when inserting it, enter the desired scale factor for the axis you want. You can also change this in your properties palette after the block is inserted.

Hi there,

If I had say 4 rectangular shapes representing 4 buildings in plan, I would have to create 4 blocks and scale them appropriately?

Looks like that's a possible solution to this problem. In another thread, another user had a similar problem regarding changing the measurements of dimensions. Looks like AutoCAD, unlike Solidworks, can only change dimensions through the scale, stretch and similar tools instead of just inputting a number.

 

Thanks anyway.

You can "just input a number" in the scale command. Another powerful option of that command is the "reference" when you give an existing distance (from the keyboard or from the screen) and the desired length for that distance. AutoCAD will transform all the selected objects accordingly.
