Hmm. Odd. There seems to be some extraneous xdata associated with the wide polyline.
Pline in block after explode:
Code:
Command: xdlist
Initializing...
Select object:
Enter application name <*>:
* Registered Application Name: ACAD
* Code 1000, ASCII string: ASC_BOUNDS
* Code 1002, Starting or ending brace: {
* Code 1070, 16-bit integer: 19
* Code 1005, Database handle: 12A4A
* Code 1002, Starting or ending brace: }
Object has 16352 bytes of Xdata space available.
Polyline after refedit/explode pline/pedit w/refclose/explode:
Code:
Command: xdlist
Initializing...
Select object:
Enter application name <*>:
* Registered Application Name: ACAD
* Code 1000, ASCII string: ASC_BOUNDS
* Code 1002, Starting or ending brace: {
* Code 1070, 16-bit integer: 19
* Code 1002, Starting or ending brace: }
Object has 16361 bytes of Xdata space available.
Was this part of a lisp routine with reactors at one time?
Edit: ps. the block moved without crashing after doing the refedit, also.
