Shrinking or redusing in size

Anonymous — Wed, 11 Oct 2017 03:23:33 GMT

I am a beginner and using AutoCad 2012. I have an object drawn and need to reduce it in size by 1/4" all round. Scaling doesn't seem to work (certainly reduces it length wise but the width is reduced proportionally. Can anyone help me complete the shrink?

Thanks,

Brian

How about using EXTEND command?.

It can scale up your object to one direction.

For more information, See this Link.

,Hello,

If you want to reduce all sides by 1/4" then scale is the perfect option.

SC > Select Object > Show base point > .25 (as the scale factor)

If you want to change only one side then you can use STRETCH (S) or you can use EXTEND (EX) as mentioned by Sonppw.

Hi,

SCALE command will reduce all of your object size by entering a scale factor. if you like to share your object with us to help you more.

If you wish to reduce the size of your objects along one axis, then usually stretch will be the go-to command. However if you wish for other elements in you drawing to reduce in size proportionally along the same axis you will need to do a work around.

You can turn your objects in a block (_BLOCK) and then insert the block again (_INSERT) but scale it along a single axis (for example x=1 y=1.5) then you will have effectively stretched your entire block along a single axis but unlike stretch all parts of your drawing will have stretched proportionally along the same axis.

I have added some screenshots to clarify the difference, as well as my .dwg in which I made the test. It still contains the block 'test' so you can practice there for your insert.

OFFSET distance 0.25" select the object and click inside it should work but can't tell for sure without the dwg to check it out.

Hi imadHabash;

Thanks very much for the reply & help. Another
reply suggested using OFFSET which worked on
reducing all sides by ¼”.

Thanks again imadHabash.

Hi Michiel;

Thanks for your reply & help. This solution
worked very well. Thought I was over my head when
I seen _BLOCK & _INSERT, but OMG, it worked.

Thanks again,

Brian

That sounds like what you're doing it to is a [presumably closed] Polyline, Circle, Ellipse or Spline, including the Erase-the-original option. The appropriate method would vary a lot, depending on exactly what kind(s) of object(s) you're working with, and in some cases would require more than one operation. For instance, a rectangle made of four Lines could have its edges brought in using Offset on each Line, but if you did that, it would also require them to be shortened, such as with Lengthen or Fillet or Stretch or Change or Trim. Stretch would do it with the use of only one command name, but you'd have to use that command four times, once for each edge. @Michiel.Valcke mentioned some other possibilities.
