If you have installed a newer version of AutoCAD (2012 or higher) you may have noticed a significant lag on the crosshair when you first launch. AutoCAD is background loading the ribbon panels to make the switching faster. If you would rather have your delays on the ribbon click, then type RIBBONBGLOAD at the command prompt and enter 0.
For AutoCAD users 2013 and higher, imagine an AutoCAD command line that starts up *instantly* and will let you open files, make changes and save the file. The new Core Console has been referred to as a ‘headless AutoCAD’ since it does not show the graphics editor (and all the interface burdon that comes with it, such as the ribbon). It is the perfect environment for running scripts since they typically don’t require any user interaction anyway.
The AcCoreConsole.exe is in the primary AutoCAD folder, you may want to consider creating a shortcut to it from the desktop. You will also find more information on the Core Console at the following URL (Kean Walmsley’s Through the Interface Blog).
Many users are not aware of this tool because it’s not on the menus inside AutoCAD. Instead use Start > All Programs > Autodesk > AutoCAD and you will find a shortcut. If you need additional control take a look at ToolPac’s Repath tool at http://www.dotsoft.com/toolpac.htm.
To add an attribute to a block that’s already defined (and used) in the drawing, simply issue the BEDIT command, select the block defined and use the ATTDEF command. It’s likely you will want to turn on the “Align below previous attribute definition” toggle. Then close the Block Editor and Save Changes.
The most important consideration now is that existing inserts don’t have a placeholder for your new attribute! AutoCAD’s built in ATTSYNC command can correct this. Issue the command, press enter to <Select> and pick any insert of your block, press enter to confirm. All the instances of your insert now display the newly added attribute with the default value. You can now simply double-click an insert to change the value in the enhanced attribute editor.
This controls whether AutoCAD picks the elevation of the snap point, the default being 0 (use the Z value). If you change the variable setting to 1, AutoCAD will use the value of the ELEVATION system variable instead. This can be very useful in an elevated drawing when you don’t want newly drawn geometry to take on the elevations of the existing geometry.
Don’t forget to set it back if you need to snap to elevations, for example when drawing 3dPolylines.
If you need to make changes to all (or most) layers in a drawing, with this dialog displayed press Ctrl+A (or right click and choose Select All), then click the operation. For example, if you click the linetype (or other) fields you are making changes to all selected items in the list.
If there are items you wish to exclude hold Ctrl while clicking to deselect them.
An extra tip along these lines. You can press Ctrl+C to copy the properties of the selected rows to the clipboard, ready to paste into other applications like MS Excel, etc.
You may want to consider creating a backup of your profile(s) in AutoCAD. Some add-ons may modify the profile in code (ours don’t) and you may make unintentional changes to the profile yourself.
Users (especially with dual monitors) can sometimes move dialogs to the secondary monitor and AutoCAD will remember that position. If the extra monitor is removed (or left behind by a notebook on the road) the dialog can’t be seen and the command appears to lock AutoCAD up. To confirm, if press ESC to cancel control will return to the editor. Here are a couple of ways to correct the problem.
When designing blocks, it’s always best to create the geometry centered around the origin of 0,0. Sometimes users can create a block from geometry in model space and it ends up difficult to use when inserting the block.
To correct this, issue the BEDIT command, select the misbehaving block, then use the move command to move the block elements to 0,0. You may need to use a specific base point (such as the midpoint of a feature) to 0,0.
On starting the CUI command you may receive alerts about unresolved files that can no longer be found. To clean these up, expand the ‘Partial Customization Files’ section and look along the list for items with an (Unresolved) suffix. If you can’t resolve the item, right click and choose ‘Unload’.
