"There is no way to remove them without "right-click" add insert into drawing (which would blow this machine up) / not an option.'
Sounds like no good bookeping practices up front, so maybe you answered your own question as usual and you have to try this.
Lets us know if it smokes! Give the first guy a kick too you got the drawing from who didn't organize and date the decriptions.
You may be able to mitigate the smoke and damage by using surface boundaries, and only import relatively smaller areas at a time...
My Mass to Volume ration can be very high at times, but if you know where the new data goes shouldn't the bad data be in direct proximity to it?
"There is no way to remove them without "right-click" add insert into drawing (which would blow this machine up) / not an option.
The other thing I've noticed, if I find the breakline and remove BL320 and go back to remove 321 as that's the one I've unidentified. After you delete 1 breakline, they renumber themselves, so you have to go on the hunt again."
You can shift-select a whole bunch of breaklines and "not use" them in the surface definition this way also. This way would not affect the numbering like you mention.
Some valid options here. I ended up going with a wholesale rebuild problem now is all the surface edits applied (swap edge, and add line point etc.) are all erased from the surface. Would need to redo everything. Looks like i'll be going through and trying to remove the breaklines individually that need replacing. At the end of the day, this whole concept is flawed IMO.
If you've done substantial manual edits I'd consider a total recreate as a last resort.
I think the Delete/Oops approach mentioned above is a good way to approximate a graphical solution. Is there some reason why you feel that won't work for you?
I have another idea, just trying to quickly get to the desired end result of a surface that deletes the old bad data in places and adds new good data in those places.
This approach might work on a small scale, but blowing this up and working with the trainings can't be a good thing. We're talking 20km of road surface.
The approach I'm now going with its to "insert all breaklines" it chugged but eventually went through and inserted all the 3D polylines as my selectable breaklines. I removed the ones I needed to redefine. The problems I'm having here, involve an overlap of a pasted surface (an area that was corrected survey and I redid it and pasted into the EG surface as a result). Now the new surface I need to add is in both areas of the original EG and the area where I have a 2nd surface that was pasted into the EG.
Out of curiosity, once I paste a surface into my EG, does the EG keep this data independently after it's added. If edit the EG will the pasted surface EG2 become outdated. Are they linked together? If I edit one will the other update. Just trying to get a grasp on exactly which areas I need to ensure are rebuilt. I'm guessing I'll need to remove the old breaklines from both and maybe just add the update to the EG to get this done with. I'd hate to have to update the EG2 so it would apply to EG considering there's overlap.
As for the mess... "Garbage in = Garbage out" no need to "edit" survey data if it was done right in the first place.
