good morningin Bentley Map often use the warp commandto adapt the topographic survey to the cadastral plan.
this command with the option Stretch changes the dgn.
When I measure on the original topographic survey(see attached dgn tr3_originale) the distance of a point from an object (in this case a tube axis in the project) I get a measure.
when I measure on the drawing ( see attached dgn tr3_warp.dgn) modified get another measure.
the warp command does the calculations.
My question is:
you can have the transformation parametersand with a macro MVBA make sure that the measurement made on the dgn modified with warp returns the real measurement of the survey
or any idea?
I apologize for my poor englishI hope I explainedmisure.zip
Hello, I am not sure if I understand properly your request.
If you do not want some sector of your map was influenced by the warp, you need to secure the sector by placing fix point on the edged of the sector. You must place source and target control points around that sector at the exact same coordinate. That should "set in place" the sector. Other solution will be to specify number of control points to be used.
For the transformation details, I will refer you to the Bentley Map help file where a short text will explain transformation methods used and weighting. I hope someone else could provide a better solutions on macro MVBA side. Sebastien Lefrancois [Bentley]
Hello. You want to keep the same distance between two elements even after the file has been warped. That is my understanding. The only way I see to "fix" the distance is by placing source and target control points on the same XYZ of the elements you do not want to move
... and If you asking the question it is because is matters. I hope someone could bring a better solution. Sebastien Lefrancois [Bentley]
