Recently, a reader asked how to plot to a specific scale from model space.
Ordinarily, I recommend plotting from paper space. You have better tools there for laying out your drawing and inserting a title block. But you can also plot from model space. In fact, this is the original method for plotting in AutoCAD, many years ago.
Here are the steps:
- From the Model tab, click the Plot button on the Quick Access toolbar or choose Output tab, Plot. This starts the PLOT command and opens the Plot dialog box.
- If necessary, choose your printer/plotter from the Name drop-down list.
- Look in the Plot Scale section at the lower-right corner of the dialog box. By default, Fit to Paper is checked, as you can see on the right.
- Uncheck the Fit to Paper checkbox.
- Click the Scale drop-down list and choose the scale that you want. In the figure below, I chose 1/4″ = 1′-0″. This is a common architectural scale in the United States.
- To check what the result will look like, click Preview. Click the X (Close) button on the Preview toolbar to exit the preview (although you can plot directly from this screen).
- Click OK to plot.
Do you plot from model space? If yes, why don’t you use paper space? I’m just curious. Leave a comment!
Besides AutoCAD, what do you use?

Multifunctional grips are small, contextual menus that let you edit the properties of an object or component. Use them to quickly edit objects.
For example, when you draw a rectangle, each vertex has multifunctional grips that let you add, remove, or stretch that vertex.
Similarly, an array has multifunctional grips that let you edit the number of rows in a rectangular array or the angle between items in the polar array.
How to use a multifunctional grip
To use a multifunctional grip, follow these steps:
- Select the object.
- Hover over a grip.
- Choose one of the options that appears.
You can also make a grip “hot” by clicking it and then right-clicking it. Along with the other shortcut menu items, you’ll find the multifunctional grip options.
Multifunctional grips have been expanded since they were introduced. For example, the rectangle’s center grip menu also lets you convert the side of the rectangle to an arc. Watch the video to see how it works.
Which objects have multifunctional grips?
The key to using the multifunctional grips is to know which objects have them. Here’s a rundown:
- 2D objects: Lines, polylines, arcs, elliptical arcs, splines, arrays, and hatches. Also dimensions and multileaders
- 3D objects: 3D faces, edges, and vertices
Control multifunctional grips with a system variable
The GRIPMULTIFUNCTIONAL system variable lets you control how multifunctional grips work. The default setting is 3 which gives you the behavior I described above; it’s a combination of the 1 and 2 settings. Here are the other settings:
- 0: Multifunctional grip options are not available
- 1: Access the options by pressing Ctrl to change grip behavior (Ctrl-cycling)
- 2: Access the options using the grip menu that you see when you hover over a grip

Several people have asked about inexplicably large files.
Kerry Overall wrote me,
I’ve seen unusually large CAD .dwg files. I had the same problem when a colleague stumbled onto a solution that greatly helped me. Open the drawing….wblock, click on “Entire Drawing” and save it. I had a simple file that was 73mb and by doing this it reduced it down to 3mb. And quickly , too.
The WBLOCK command writes (saves) the objects in a drawing as a new drawing. You can specify specific objects or the entire drawing.
A bonus is that you lose many settings in the current drawing. You can therefore use this technique to troubleshoot problem drawings that don’t behave the way you want them to. It’s often hard to ferret out the settings that might be causing the problem — such as system variables — so moving the objects to a new drawing can be an easy fix.
To be more precise, here are the steps:
- If you want, you can select objects in advance.
- Type wblock on the command line or choose Insert> Block Definition panel> click the Create Block drop-down arrow and choose Write Block. (It’s easiest to just type it on the command line.) The Write Block dialog box opens. If you pre-selected objects, the number of objects appears in the Objects section of the dialog box.
- To write the entire drawing, choose Entire Drawing at the top.
- You can choose a base point. If you want to be able to insert the drawing (or the selected objects) using a base point on one of the objects, for example, click the Pick Point button and specify the base point.
- In the Objects section, you can choose to retain the objects in the current drawing, convert them to a block, or delete them from the drawing.
- In the Dstination section, click the Ellipsis button and browse to the location where you want to save the new drawing. Give the drawing a name and click the Save button.
- If desired, choose units from the Insert Units drop-down list. You can choose Unitless. You can even choose light years or parsecs if you’re thinking really big!
- Click OK.
If you did these steps to make your drawing smaller, go into Windows Explorer and check the size of the original and new drawings.

Most mice have a wheel and you can use it in a number of ways — scroll it in 2 directions, click it, and double-click it. Plus, you can combine keys such as the Shift key with the mouse wheel to get even more capabilities. AutoCAD makes good use of your mouse wheel. Here are some of the options.
System variables that affect the mouse wheel
3 system variables affect how your mouse wheel works.
ZOOMFACTOR: This system variable sets the amount of magnification change that occurs when you scroll the whell forward or backward. You can choose from 3 to 100 and the default value is 60. A higher value changes the magnification more.
ZOOMWHEEL: This sets the direction of the scrolling. By default, this is set to 0, which means that when you scroll the wheel forward you zoom in and when you scroll it backward, you zoom out. If you set the value to 1, you reverse the action. Most people change this setting when they have other software that works the opposite of the AutoCAD default and they want the zooming to be the same in all their software.
MBUTTONPAN: By default (set to 1), when you press the mouse wheel and drag, you pan across your drawing. However, when you set this system variable to 0, the wheel acts like a middle button and supports the action that you define in the CUI or CUIX menu file, which could be just about anything.
Mouse wheel actions that you can use
Here are the actions you can perform when MBUTTONPAN is set to the default of 1.
Zoom in or out: Rotate the wheel forward to zoom in, backward to zoom out. (As mentioned above, you can change the direction with the ZOOMWHEEL system variable.)
Zoom to extents: Double-click the wheel button.
Pan: Press and drag with the wheel button.
Pan (joystick): Press Ctrl and the wheel button and drag the mouse. This is used in 3D, although I’m not sure I understand exactly what’s happening. Try it out and see if it’s useful for you.
3D Orbit: Press Shift and the wheel button and drag the mouse.
Free Orbit: Press Ctrl, Shift and the wheel button all at once and drag the mouse. You’ll see the 3D orbit arcball as you do this.

There’s no reason to recreate the wheel – or text or dimension styles, if you have them elsewhere. The easiest way to import a text or dimension style from another drawing is to use the DesignCenter.
Follow these steps:
- Go to the View tab, Palettes, DesignCenter or type designcenter on the command line.
- From the Folder list (it looks a lot like Windows Explorer) navigate to the folder, then the drawing that has the text or dimension style that you need.
- Click the drawing’s Plus sign to expand it and choose the type of elements that you want to import, such as a text style.
- On the right, you’ll see a list of the text styles that are available in the drawing. Drag the one you want onto the drawing area.
You can also use the Content Explorer, although the set-up process is more complex. Here are the steps:
- Click the Plug-Ins tab, then click Explore.
- If the folder where the drawing you is not listed, click Add Watched Folder at the bottom.
- Navigate to the folder, select it, and click OK. AutoCAD scans the drawings in the folder; this process may take some time. The Content Explorer works best when you plan in advance.
- When the process of scanning is done, or if the folder you want is listed, you can do one of two things:
- If you know the name of the element, enter it in the Search box at the top of the Content Explorer.
- If you know the location and name of the drawing, double-click the folder and navigate to the drawing. Double-click the drawing to display its elements.
- When you see the element you want, such as a text style, drag it onto the drawing area to import it into your drawing.

A donut looks like a wide circle with a hole in it but is actually made up of 2 semi-circle polylines. You can use donuts for electronic schematics, as trees or bushes, or as symbols.
Here are the steps to create a donut:
- Choose Home tab and expand the Draw panel to find the DONUT command, or type donut.
- At the Specify inside diameter of donut <2.0000>: prompt, type the diameter of the hole. To create a filled circle, type 0. The command remembers your previous diameter and uses it as the default.
- At the Specify outside diameter of donut <4.0000>: prompt, type the diameter of the entire donut.
- At the Specify center of donut or <exit>: prompt, place the donut by specifying where you want its center to go.
- The command repeats automatically, so the next prompt is Specify center of donut or <exit>: Continue to specify center points or press Enter to end the command.
Fun fact: You can type doughnut to start this commend.
What do you use donuts for? Or, did you use donuts in the past and replace them with something else? leave a comment to share your experience!
Layers are a big issue when it comes to maintaining drawing standards. Where you work, you may have lots of rules about which layers your drawings can have.
Xrefs can be a problem for drawing standards, because when you attach an xref, its layers come along for the ride. This is especially an issue when the xrefs come from an outside organization, such as a subcontractor.
You can have AutoCAD notify you when new layers are added to a drawing. This layer notification feature doesn’t work with a drawing standards file but is just based on the layers that exist in your drawing. For more information about drawing standards files, see my post, “Use a Standards file to bring an AutoCAD drawing into line.”
Set up layer notification
Here are the steps to set up layer notification:
- Choose View tab, Palettes panel, Layer Properties (or type layer) to open the Layer Properties Manager.
- Click the Settings button (it looks like a wrench) to open the Layer Settings dialog box. You’ll use the top half of this dialog box.
- Check the New Layer Notification checkbox.
- Check the Evaluate New Layers Added to Drawing check box.
- Keep the default option, which is to evaluate only new xref layers, or choose Evaluate All New Layers if you want to be notified whenever a new layer is added. If your templates already have all the layers you need, this option can help prevent inexperienced users from adding layers. At least, they’ll see a notification!
- To specify when the notification appears, check the Notify When New Layers Are Present checkbox.
- Use the other checkboxes it determine when the notification appears.
- Click OK.
Note: If you don’t check the Notify When New Layers Are Present checkbox, you won’t see a notification bubble, but can still check for unwanted layers by right-clicking the Unreconciled New Layers alert icon on the right side of the status bar and choosing View Unreconciled New Layers. The Layer Properties Manager opens with a filter that displays only those layers. You can then delete them or change their properties.
What to do when you get a notification
When you see a notification bubble or dialog box, click its link to open the Layer Properties Manager (with a filter that displays only unreconciled layers) where you can fix the problem.
When you start customizing the ribbon, you may want to create a new tab to hold all of your custom commands. On the other hand, you may want to add custom commands to existing tabs and put them in context.
If you want a new tab, here are the steps:
- Type cui to open the Customize User Interface dialog box.
- Expand the Ribbon item. Right-click the Tabs item and choose New Tab. Type a name for the tab (keep it short).
- Right-click the Panels item and choose New Panel. Type a name for the panel.
- Drag the new panel to the new tab.
- To add the tab to your workspace. select the Workspaces item and choose the workspace. Find your new tab under Ribbon, Tabs and drag it to the Ribbon Tabs item in the Workspace Contents box. You have to be careful to drag without clicking your custom tab (and releasing the mouse button). If you expand the Ribbon Tabs item, you now see that your custom tab is there. You can also click OK to close the dialog box and see that the tab appears on your ribbon.
- In the Customization in All Files section, under Panels, expand your new panel. A panel comes with a preset structure that you can change. Find the command in the lower-left box of the dialog box, called the Command List. If you want to add custom commands, choose Custom Commands from the drop-down list in the Command List section. This will help you find your custom commands more easily.
- If your command doesn’t have a button, select it from the Command List and use the Button Image section at the upper-right to choose and edit your button. Click Save and save your image. It will be a BMP file. Remember the location!
- To assign the image to the command, choose the command from the Command List section. Click the Small Image item in the Properties pane on the right. Click the Ellipsis button and browse to your BMP file. (Note: It’s possible to lose this type of customization when you upgrade to a new release of AutoCAD.)
- To add the command to your panel, drag it from the Command List to Row 1 in your custom panel. This means that you’re dragging from the lower-left box to the upper-left box in the dialog box. There are lots and lots of panels, but yours should be at the bottom of the list.
- Click Apply and OK. Click your new tab to find your custom commands.
Here is my custom tab.
Here is the panel with 2 custom commands on it.
