Issue with closed Polylines & Overlapping Objects.

[Anonymous]

Hi All,

I have a dwg. file that i need to upload into a third party system, which is a basic floor plan of a building consisting 6 layers, 1 each to define the space, floor & building, and 3 text layers to give each space an ID, Name, class. I have done this multiple times on other drawings without issue, but it appears this file or drawing is the devil 😂

When uploading i am getting errors, such as 

1) "layer data, failure reason: the value on the name layer is blank"

2) "entity handle: 2xxxx, failure reason, the boundary is empty"

Things i have tried,

-I have also put in place a LISP function to identify Gaps in polylines,

-I ensured all polylines are closed

-I have ensured all objects match those of layer type defaults

-I have used the Purge Function. 

-I have tried the autoconstraint command. 

-I have tried the Plan/World command.

-I have tried the boundary function (with errors, more below)

-I have ensured no polyline are intersecting 

Other background

Commonly when i may receive a boundary error, i then use the zoom/object command to search the entity handle, find it, review the corners and fix appropriately. it may be simple random extension of a line. 

I believe the the root cause of my problem is

When i select an object that is a closed polyline, and i use the overkill command, it will identify an overlapping object and delete, the polyline now is now no longer "closed", so now i  make it closed using the properties and selecting yes, now i will have a overlapping again, this is just a cycle on repeat, why is this happening???? 

Also to add when doing the boundary command, i receive the attached error, but all polylines are closed. This causes me to think the only potential problem i believe is the UCS setup, but for the life of me i do not recall making any changes to this, and i cant quite grasp how to to ensure select all object and align to the UCS/World.

Also attached a snipit of some spaces that appear to be uploading successfully, and yes i viewed the properties of these polyline or area and tried to see any difference, no luck.

Any assistance or guidance would be appreciated.

Hi,

i understand your issue in general . since we have your drawing , would you please guide us to look where in your drawing about the errors that you found ?

Appreciate the response,

the issue lies in the AREA-SPACE layer i suspect, these are simple outlines of a room. i believe multiples of these "area-space" polylines are having this issue. I do not know why some have been successful and some not.

These "area-space" polylines need to be a closed polyline to be recognized and uploaded by the third party system, the three separate text labels need to be placed with in to give the room identification,

When uploading the drawing, the plug in asks you to define the text layers, i suspect it is then looking for the a single "area-space" layer boundary, which is where the errors occur, because its telling you the boundaries dont existing even though they are closed? then i assume there must be duplicates or overlapping lines..

Is it to do with the UCS? errors between closing polylines and the overlapping objects?  

Attached image of the plug in window snipit, you can imagine you tell the plug in which layers to identify, these layers are created based on defaults such as colour, name convention etc. when you tell the plug in to upload the floor plan tot he building floor you choose it will tell you which one are successful and the errors.

would you please check the attached CAD drawing AREA-SPACE layer ? any changes ?

Hi,

That worked, so the third party plugin is now is picking up all those area-space polylines, 

Can you please share how you did this? or what was the issue?

FYI, the two error are just duplication's in the text label which i will fix.

Great !! when i try to start Boundary command in your green shapes i face the same error that you have !! this took me to isolate that layer ( Layiso command ) then Explode them all . i make a new boundary to all exploded shapes . some times when working with big areas of rectangles and using grips gives errors in other CAD procedures like Boundary or Hatch or any command that need to scanning through . also making your unclosed polylines closed from Prosperities pallet some times make such an error .  So , the idea is to redraw your rectangles make you get out from such an errors .

hope that solve your issue . 

All the best ..

appreciate it,

May i ask when you did the explode of all the polylines rectangles? did you redraw another polyline over the top? or use a command to join the lines back together?

PEDIT i assume or another command that i may not know of?

No , just use BOUNDARY or BPOLY ( Pick Points ) command .
