AutoCAD - Hidden line/Centerline/Dashed line won't join at vertices. Gap between final dash and end point vertex of line.

[BigBoyCAD]

Hi.

Using AutoCADLT 2025.

Problem: 

- When drawing both 'polyline' and 'line' using Hidden/Centerline/Dashed linetypes, a gap starts to form between the final dash and the end vertex of the line as the line lengthens.

Info:

(in the following 'line' refers to both polyline on line)

- The gap between the last dash and the end point vertex of the line remains even it is drawn as a single polyline/line.

- This means that some corners have gaps.

- This issue occurs with PLINEGEN variable set to both 1 & 0.

- This issue occurs when manually enabling/disabling 'line type generation' in properties once the polyline is selected. 

- Filleting/joining these lines does not solve the problem.

- Exploding and then filleting/joining these lines does not solve the problem.

- The gap only occurs on the end point of the line. Not the start point.

- When stretching the line, whether using start point or end point to stretch, the gap on the end point grows. 

- This issue does not occur on other work computers using the exact same layer, linetype, linetype scale and same dwg.

I have attached a .png to demonstrate the issue.

Any help on this would be greatly appreciated.

Thank you very much.

have you installed the latest 2025.1 LT update?

Hi Paul.

Yes I have the most recent update installed.

Unfortunately the problem persists.

On this particular computer does the same problem occur in a new drawing?

What if you create a new Windows profile with local admin rights and then sign in using that new profile?

Worse case would be to do a Reset

in case it's a graphics card issue, try disabling Gfxdx12 by setting that to 0 and then restart LT.

Update:

It seems the issue may be caused by a variable on my computer.
The issue transfers to another computer when a .dwg I created is opened on the other computer.

I have tried resetting AutoCAD. It didn't fix the problem.

I tried all else to no avail... then changing the 'Gfxdx12' variable to '0' sorted the issue.

Thank you very much mate.

Greatly appreciated.
