I have applied the workbench below to first clean the lines and then to convert them to polygons. The correct number of polygons should match the number of texts. My thought is that the tools applied to clean the lines are not sufficient.

What other tools should be included in the workbench to first clean the lines:
1. Remove duplicates
2. Ensure lines snapping
Thank you

I think segment snapping before the Intersector would be effective. And stroking arcs (and ellipses if exist) before the snapping might also be effective.
In addition, found these exceptional cases in the data.
1) three polygons that contain multiple texts for each.
2) one polygon that contains no text.
3) one text that does not correspond to any polygon.
4) a few lines that don't become polygon edges.

Sure the CAD data is really “dirty”. This is why we need to clean it as much as possible.
1. I have applied the ArcStroker
2. But couldn’t find the “segment snapping” tool.
However, I think that the number of polygons derived from lines should be CLOSE to the number of texts. Otherwise, this will indicate that the lines are not yet cleaned.
By the way, there is no effect neither for the “ArcStroker” nor for the “matcher”.
What other tools should be applied to make the number of polygons quite close to the number of texts?

The data is dirty to a degree that all tools will never clean it. I check the resulted polygons and found out many slivers.
Better if the data is correct at the level of AutoCAD and then applying FME.

I inspected your data with this workspace, FYI.

"I think segment snapping before the Intersector would be effective. And stroking arcs (and ellipses if exist) before the snapping might also be effective."
This is the result of my inspection about your data. Red polygon contains no text; Green polygons contain multiple texts for each; Red text (left-top corner) does not correspond to any polygon.

I tried to build same workbench as yours but
1. I fail to build the testfilter
2. To enlarge the text to be visible in the “fme inspector”
Could you please share your workbench?

To enlarge text size in FME Data Inspector, modify "fme_text_size" attribute value.

I have applied the same settings for the “testfilter” but with no luck.

And, which of the ArcStroker and the Snapper should be used previously?
See more carefully my workspace, posts, and related help docs., please.

Very much appreciated for the massive efforts and help.
The LineCloser transformer has done the job in my case.
