How to scale in AutoCAD, all about using Scale in drawings

On this article, I’ve included as many situations as potential where scaling is required and I’ve explained them with related examples.

Easy Scale command

Using scale command you’ll be able to change the dimensions of an object in AutoCAD. To elucidate scale command I’ll use this easy window block which has the dimensions of 10 unit alongside the X-axis and 15 models alongside Y-axis.

Select the scale software from Modify panel of the home tab or use its command SC.

Now choose the window drawing and press enter. Now you need to select the base level. The bottom level will remain fastened when the item is scaled, in this case, I am using the decrease left corner of the window as the base level.

The command line will now immediate you to specify the scale issue. This scale issue truly determines the final measurement of your window.

A scale factor of 0 to 1 will lower the dimensions of your object (in this case window). For example, a scale factor of 0.5 will scale back the general measurement of your drawing to half of its unique dimensions and a scale issue of zero.25 will lower the dimensions of the thing to one-fourth of the unique measurement.

Similarly, scale factor higher than 1 will improve the dimensions of the drawing. For example, a scale factor of 2 will improve the dimensions to twice of its unique worth and a scale factor of 3 will improve the dimensions 3 times.

Enter the scale factor and press enter. In this case, I’m using a scale factor of two, the ultimate measurement of the thing will grow to be 20 unit along the X-axis and 30 unit along the Y-axis.

Further tip: If you need to hold the unique object even after altering the scale then click on on “Copy” choice from the command line when prompted for the scale factor.

Scale using reference

Think about this state of affairs, we have now the window used in the previous example with the size along the X-axis 10 models and peak of 15 models. Now we would like to change the dimensions of this window so that the length alongside the X-axis now turns into 17 unit and the peak should change proportionally.

Now, in this case, you need to use the “Reference” choice of scale command to change the dimensions of the item.

As soon as again begin the scale command and then select the window and press enter. Now specify the lower left nook of the window as the base point, you need to use another base level as nicely if you’d like.

Now the command line will immediate you for scale issue, on this immediate click on on the Reference choice from the command line.

Now the command line will prompt you to specify the reference length. Sort 10 and press enter, this is the current size of the window alongside the X-axis.

Now command line will prompt you to specify the new length which you want for the 10 unit line of the window. On this case sort 17 and press enter again.

Now the bottom of the window will grow to be 17 models in length and peak of the window will mechanically change proportionally.

As you’ll be able to see, this command is sort of useful if you’d like to change the dimensions of an object with reference to different present objects or any reference length and in this case, you obviously don’t want to specify the scale issue.

Scaling Blocks

The scale instructions explained above will work for block references too and you don’t need to use any particular property to sale blocks. Nevertheless, you’ll be able to scale your blocks with totally different scale elements alongside the X, Y and Z axis which I will clarify here.

I will use this drawing of a easy chair to clarify this.

First, we’d like to convert this easy object into a block and for that, you need to use B command. This article explains extra about making a block in AutoCAD.

Just be sure that while creating the block you keep “Scale Uniformly” field unchecked as proven in the image here.

Upon getting your block prepared you’ll be able to change scales after which insert it in your drawing. To insert the block use I command.

Sort I and press enter, the Insert window will present up. On this window, you possibly can assign the scale of the block alongside X, Y and Z axis individually. Should you hold the value of scale factor similar alongside X, Y and Z axis then the overall measurement of the block will change.

Let’s use the scale issue of 1 along the X-axis and 1.5 alongside the Y-axis, I’ll maintain scale alongside the Z axis as 1.

Now click OK and click on at some extent to insert the block. The block will appear to be picture B shown under where image A is the original block at the general scale of 1.

As you possibly can clearly see the block, in this case, shall be scaled to an element of 1.5 solely in the Y path and never in another course.

Scaling Xrefs and pictures

Xrefs or external references are entities like DWG information, PDF or photographs that can be inserted in a drawing as a reference. You’ll be able to scale your Xrefs whereas inserting them or you’ll be able to change their measurement even after inserting them into the drawing.

For this example, I’ll use a DWG file but you should use the same technique for PDF file and Pictures.

Sort ATTACH and press enter, the connect window will open up. Choose DWG from the format dropdown as proven in the picture under. Now select the situation where your file is saved then choose the drawing and click on on open.

The Xref window will open up where you’ll be able to assign totally different scale for various axes and you may even maintain it at 1 for all the axes to hold the original measurement of hooked up Xref.

Even after including the Xref you’ll be able to change its scale using the property palette. Just choose the Xref from drawing area then sort PR and press enter. The property palette will open up, scroll down in the palette and change the scale from the geometry tab of the property palette.

You can too use scale command to change the overall scale of hooked up Xref.

In an identical approach, you possibly can change the scale of hooked up pictures and PDF information. Right here I will connect a picture of the floor plan to clarify it.

Sort ATTACH and press enter then choose an image and click OK. Specify some extent in the drawing are to insert it and press enter to accept the default scale of 1.

After inserting the picture in my drawing it appeared like this.

This picture is just not correctly scaled ie the 10′ size on the image is just not truly 10′ on the drawing. To fix this we’d like to scale this image again with reference to any present dimension in the ground plan image.

Let’s take the reference of 10′ length which is on the top of this flooring plan.

Sort SC and press enter to begin the scale command. Now select the floor plan image and press enter again. Click on on the highest left corner of the picture as the bottom point after which choose the reference choice from the command line.

Now click on at level A then point B (refer picture under) to specify the reference and sort 10′ and press enter again. Now the space AB on the picture will change to 10′ and other distances will regulate accordingly.

In this case, I have used Architectural models so ensure you change the unit to architectural before using scale choice in this example. To vary it to Architectural sort UN press enter after which select Architectural from Length drop-down as shown in the image right here.

Scaling Hatches

Once you add hatches in any closed area it might appear as if a strong pattern or it might not appear at all. Typically occasions this occurs because of the improper scale of hatches which might be simply adjusted from hatch creation panel to make them look right.

Begin hatch command from the Draw panel or use its command H. A short lived hatch creation tab will present up. Choose the hatch pattern after which specify the world where you need to add the hatch.

If the dimensions of the hatch sample could be very small or very giant then change its scale from the scale subject of properties panel as shown in the purple field of the picture under.

If the pattern could be very small you then want to improve the value in the scale area and if the sample is extensively spaced you then need to decrease the scale value. Here is how my ANSI 31 hatch sample seems to be on a scale of 1, zero.05 and 50.

Even after adding the hatches if you choose them again it’ll open hatch creation tab from where you’ll be able to again modify the hatch scale or other properties.

It’s also possible to change the hatch scale from property palette, simply choose the hatch sample, then sort PR and press enter. It will open the property palette, scroll down to the Sample part and alter the scale as proven in the picture under.

Scaling Viewports

Drawings are sometimes made in mannequin area however text, title blocks and other required info associated to drawing are usually added in the format or paper area. In this part, I’ll explain strategies of creating viewports in paper area and changing their scale to fit the drawing.

I am using this easy elevation drawing to explain this function.

This drawing is in mannequin area but we’ll insert this one in viewports of various scale in the format. Start by choosing Format 1 from the bottom left tabs, it’s also possible to hit the + icon to make new format tab.

The format area will open up with a default viewport and your mannequin area drawing shall be mechanically added in it. Delete the prevailing viewport and then click on on the Page Setup choice from Format tab as shown in the picture here.

Click on on Modify button in the page setup manager window and change settings of the format like printer/plotter and web page measurement. I have selected DWG to PDF.pc3 in the plotter and ANSI A because the paper measurement.

After making these modifications click OK to exit all open home windows. Now we are all set to make our viewports.

Sort -VPORTS and press enter (don’t overlook to add the sprint before vports). Now click on at some extent shut to the top left of the format properly within plotter margin and then click at one other point to make a rectangular viewport. Repeat the command and make two extra rectangular viewports in the identical format view.

After making all the viewports your format area ought to appear to be this.

At present, the scale of drawing contained in the viewport is routinely set by AutoCAD however you possibly can change it manually. To vary the scale select the viewport boundary then change the scale from scale choice of status bar as shown in the picture here.

If the scale which you want to use just isn’t obtainable in this record of viewport scales then you possibly can add your personal customized scale too. To add the customized scale choose any viewport then click on scale choice from the status bar as shown in the picture above and choose Customized choice from the listing of scales.

“Edit Drawing Scales” window will open up. Let’s assume that we would like to add a scale of 1:6 in this record, for that click on on add button.

Within the identify area of the subsequent window add 1:6 and then add 1 in the paper unit and 6 in the drawing unit area. Click on OK to settle for the modifications and shut all open home windows.

You will notice that your new scale is now added to the record and now you can use it in your viewports. You can too watch the video proven under to know extra about scaling drawings in paper area or layouts.


So, this was all about using scale choice in totally different instruments and options of AutoCAD. There are nonetheless some features like the Annotative scale in AutoCAD and use of scale in format area which I’ve I have not included right here as they’re mentioned already in relevant articles and movies.

I hope you can see this article useful, if in case you have any query related to this article let me know in the comments under and don’t overlook to share the article.
