If a LISP routine or a manual input forces a density calculation that falls out of bounds, AutoCAD triggers an integer error.
Mastering these small prompts makes the difference between a frustrating AutoCAD session and a smooth, professional workflow.
Several underlying AutoCAD system variables accept maximum inputs of exactly 20000 . If a customized AutoLISP script, third-party add-on, or manual command attempts to push a variable beyond this hardcoded threshold, the software blocks the operation. Step-by-Step Solutions Solution 1: Adjust the Hatch Scale and Density Limits
Simply type a whole number between 1 and 20000. For example: autocad please enter an integer from 1 to 20000
When confronted with this message, use the following troubleshooting steps to correct your input and proceed with your work. Step 1: Verify Your Input Format
If the error appears while modifying line appearances or working within viewports, your scale factors are likely out of bounds. Step 1: Reset Global Linetype Scale Type LTSCALE in the command line and press .
Command: ARRAY Enter number of items: 'CAL >> Expression: 10000+5000 Result: 15000 If a LISP routine or a manual input
Type PURGE and press . Click Purge All to remove unused blocks, layers, and linetypes that might carry corrupted scaling data. Summary of Key Variables System Variable Default Value Maximum Value MAXHATCH
This prompt appears when you are using the SCALE (or ZOOM ) command in AutoCAD and the software expects a whole number (an integer) to define a magnification factor or a viewport scale.
Retry your action to see if a visual dialog box provides more context. Step 3: Run the AUDIT and PURGE Commands If a customized AutoLISP script, third-party add-on, or
If you are trying to view a list of layers, blocks, or linetypes and the list isn't appearing correctly—or you see the integer error—check your MAXSORT settings. Type into the command line and press Enter.
Are you seeing this error specifically when opening the tab, or does it happen immediately upon typing the OPTIONS command? Cannot Access OPTIONS Dialog BOX - Forums, Autodesk
This restriction is hard-coded into specific AutoCAD commands and features to prevent errors, memory overflow, or nonsensical values. For instance, asking AutoCAD to generate 50,000 copies of an object in an array could crash your system or hang the software.
Before diving into solutions, it's helpful to know why AutoCAD uses this specific range. The 1-20000 limit is commonly associated with the , which controls the display smoothness of curves and circles by increasing the number of line segments used for on-screen representation. A higher value produces smoother visuals at the cost of performance, while a lower value yields a faster display of simpler, faceted shapes.
Here’s a review based on a realistic user experience with the AutoCAD prompt:
