If you apply a dashed or complex linetype to an incredibly long polyline, and the linetype scale ( LTSCALE ) is set too small, AutoCAD attempts to generate an infinite number of dashes. This can occasionally conflict with internal regeneration limits. Select the problematic line or layer. Open the Properties palette and look for Linetype Scale .
Problem: Attribute definition for a part number required values up to 50,000. Error: Appeared when saving the block. Solution: Changed attribute type from Integer to Text/String, then entered numbers without integer validation.
When you see this specific error, it means you or a running script attempted to input a value of 0, a negative number, or a number greater than 20,000 into a field that strictly requires a whole number (integer) between 1 and 20,000. Common Triggers and How to Fix Them
How to Fix the AutoCAD Error: "Please enter an integer from 1 to 20000" autocad please enter an integer from 1 to 20000
❌ You might be in a different command mode. Press Esc to cancel, then re-enter the command.
Alternatively, increase your hatch scale factor so AutoCAD doesn't have to draw as many dense lines. 2. Array Command Limits
Do not use the command line for this. Select the viewport, go to the Properties Panel (Ctrl + 1), and find Standard Scale . Select your scale from the dropdown list to avoid manual calculation errors. If you apply a dashed or complex linetype
Once you've resolved the issue, here are the best practices to ensure it doesn't return.
If you attempt to hatch a massive area with a very dense pattern scale, AutoCAD will try to generate hundreds of thousands of lines. If the calculated lines exceed the internal safety ceiling, or if a script tries to force MAXHATCH outside its allowed boundaries, the error triggers.
| Question | Answer | |----------|--------| | | AutoCAD needs a whole number (1–20000) for a command setting. | | Is it an error? | No — it’s an input constraint. | | What should I type? | Any integer 1 through 20000. | | Can I change the range? | No — it’s hardcoded per command. | | What if I need more than 20000? | Use multiple arrays or batch processing. | Open the Properties palette and look for Linetype Scale
Here are the most effective ways to resolve this issue based on the scenario: Solution 1: Divide Large Arrays (Workaround)
The error message also appears in other scenarios, each with its own specific integer bounds:
Use the POLYLINE ( PL ) command to draw temporary dividing lines across your target area.
If you accidentally typed 10,000 (with a comma) or 10.000 (with a decimal point), AutoCAD sees that as a non-integer. Remove commas and decimal points.
When filling a large or highly detailed area with a hatch pattern, AutoCAD calculates individual hatch lines. If the area is too large or the hatch scale is too small, the number of lines exceeds AutoCAD's default limit, triggering the error.
