Open Roads crashes importing a CAiCE .PT4 file

When attempting to import a CAICE .PT4 file ORD hangs up or crashes. I exported the data out of CAiCE into a .KCP file containing just points and a .KCP file containing just survey chains. The points .KCP file will import just fine but the chains .KCP file import will crash. After many hours of aggravating chain editing I have come to the conclusion that it is a chain list issue.

For whatever reason there are times that if I have edited a survey chain CAiCE will place the same point number in a chain list back to back. Can't figure out yet why this happens. Probably never will. The repeat points do not seem to be coming out of EFB through the .OBS file so at this point I can only assume that the double points appear during the chain editing process.

These back to back numbers show up in .KCP files exported out of the database as illustrated below:

*** SURVEY CHAIN ***

CN: FBWB1

ST: 0.000000

ZN: 1

JN: 1

AT: F

FC: LLBW

AN: 0

DS: 6" WIDE BROKEN WHITE LANE LINE

CP: EBWB8,FBWB14,,15-15,1-7,FLL23

At this point the only fix to this is to edit the chains .KCP file line by line and remove the duplicate points from the point list. Maybe the import process could check for these occurrences and remove them?

Do you have a small sample file you can upload for us to replicate the issue (original .PT4 along with the chains KCP)? We can log a defect or at a minimum get development to look at an enhancement if this is a regular process in which Caice outputs the edited data.

It seems like you have it narrowed down to this specific issue with the point names, so I don't think this is related but you may check out this issue reported a while back with regards to the PT4 import. https://communities.bentley.com/products/road___site_design/f/geopak-inroads-mx-openroads-forum/136145/caice-pt4-file-import-issue

Hi Chris,

Thanks for the response.

I finally managed to get the database that I was working cleaned up and imported into ORD. But I have lots more that I can send you so I will find one that crashes ORD and send it to you along with the corresponding .KCP files.

I read through that other .PT4 thread and was kind of surprised to see long survey chains mentioned as a possible cause. When AGA was still a viable company and maintaining CAiCE one enhancement that was carried out was to make survey and geometry chains have an infinite length. This was done because at the time line strings in Microstation of infinite length were also supported. Maybe that is no longer the case.

I'll find a proper set of files to send to you.

Bill
