However, you can scale your blocks with different scale factors along the X, Y and Z axis which I will explain here. The scale commands explained above will work for block references too and you don’t need to use any special property to scale blocks. Now the base of the window will become 17 units in length and height of the window will automatically change proportionally.Īs you can see, this command is quite useful if you want to change the size of an object with reference to other existing objects or any reference length and in this case, you obviously don’t need to specify the scale factor. In this case type 17 and press enter again. Now command line will prompt you to specify the new length which you want for the 10 unit line of the window. Type 10 and press enter, this is the current length of the window along the X-axis. Now the command line will prompt you to specify the reference length. Now the command line will prompt you for scale factor, on this prompt click on the Reference option from the command line.

Now specify the lower left corner of the window as the base point, you can use any other base point as well if you want. Once again start the scale command and then select the window and press enter. Now, in this case, you can use the “Reference” option of scale command to change the size of the object. Now we want to change the size of this window so that the length along the X-axis now becomes 17 unit and the height should change proportionally. In this case, I am using a scale factor of 2, the final size of the object will become 20 unit along the X-axis and 30 unit along the Y-axis.Īdditional tip: If you want to keep the original object even after changing the scale then click on “Copy” option from the command line when prompted for the scale factor.Ĭonsider this scenario, we have the window used in the previous example with the length along the X-axis 10 units and height of 15 units. For example, a scale factor of 2 will increase the size to twice of its original value and a scale factor of 3 will increase the size three times.Įnter the scale factor and press enter. Similarly, scale factor greater than 1 will increase the size of the drawing. For example, a scale factor of 0.5 will reduce the overall size of your drawing to half of its original dimensions and a scale factor of 0.25 will decrease the size of the object to one-fourth of the original size. This scale factor actually determines the final size of your window.Ī scale factor of 0 to 1 will decrease the size of your object (in this case window). The command line will now prompt you to specify the scale factor.

The base point will remain fixed when the object is scaled, in this case, I am using the lower left corner of the window as the base point. Now select the window drawing and press enter. Select the scale tool from Modify panel of the home tab or use its command SC.

To explain scale command I will use this simple window block which has the size of 10 unit along the X-axis and 15 units along Y-axis. Using scale command you can change the size of an object in AutoCAD. In this article, I have included as many scenarios as possible where scaling is required and I have explained them with relevant examples.
