scaling using object snaps

[gib65]

When I scale, I use object snaps to specify the base point, but I don't seem to have the option of using object snaps to specify the extents of the object I want to scale. Instead, I'm asked to specify a scaling factor.

What if I want to scale something down to match the size of another object using that object's snap points. For example, I have a floor layout and a wall. The wall is too big so I want to scale it down but I don't know the exact size. I can move one corner of the wall onto the corresponding corner of the floor layout using object snaps. Now, how would I scale the wall down so that the opposite corner matches up with the corresponding corner of the floor layout? That is, I want to click on the opposite bottom corner of the wall and then click on the corresponding corner of the floor layout and have the wall scale down accordingly. Is this possible?

Try the "align" command, it has an option to scale to the points you select for aligning.

In addition to CarlB's advise.

After specifing a base point the user is offered-
Specify scale factor or [Reference]:


Type "r" at the command. You will be able to do what you described, albeit in a somewhat convoluted manner.

For a more fluid interaction I use the macro:
^C^C_Select \scale previous ;\r @;

Similarly, this is a more user friendly rotate with reference:
^C^C_Select \rotate previous ;\r @;
