Is there a function in Access to calculate the station and offset of a KNOWN point to a selected alignment? If so, I can't find it. And I also would like to do the reverse of that, and key in NEW point station and offset to a selected alignment.?ÿ
For example: I was asked to provide the station and offset of a previously located utility pole in relation to our proposed roadway alignment.
Also is there anyway to calculate an intersection of two alignments? Or to calculate the intersection of a line and an selected alignment??ÿ
For example: If I have a skewed pier line, and want to calculate the intersection of that pier line with the proposed roadway alignment.
Thank you!
I found out how to find the station and offset of a KNOWN point to a selected baseline...but I am still trying to figure out how to calculate a NEW point by station and offset relative to a KNOWN alignment. I know you can stake out station and offset to an alignment, but I just want to calculate a point by station and offset to an alignment. It seems to me, that the software will only let you create a point station and offset to just a line, or two selected points.
Go to KEY IN,?ÿ when it asks for point name, hit OPTIONS at the bottom and change it to STATION and OFFSET.
For the intersectiong alignments, youll probably have to create points at one end of each line, then do a bearing-bearing intersection in COGO.
The only problem with that work around is that it wont work for an alignment in a radius.?ÿ
For instance, yesterday I needed to layout an offset to the outside edge of deck (which is in a curve) but along a skewed abutment line. This is excactly when I could use the ability to intersect a line, or two points with an alignment.?ÿ

The bearing distance function does that
Im not following exactly what you are trying to do, but in a curve I usually put the radius point in the file so I can turn off skews to a curve.?ÿ
Thanks for the KEY IN info for station offset, not sure if I ever would have found that.
This is what I'm trying to do. Not sure if this file attachment will work.....

From what I can tell from that drawing, the 70 deg. skew is off the other baseline (I assume it's off the tangent since it's just before the PC, even though it is shown off the curve.)?ÿ So create a point at the center of the pier on that alignment, and create the radius point of the curve you want to offset, then it's a bearing/distance intersection.?ÿ Easier to do in CAD than in Access, but it's doable.

That looks like you are trying to intersect the black line with the red line, there is a routine in Access under calculate a point called bearing bearing for that, you need to have a point on each line and known bearings. I would do that in calculate a point, pull down to the bearing bearing function.

Or via COGO - Compute Point - Four point intersection if you have 4 points.
Ever downloaded and read the Trimble General survey Help file? Lots of info and well explained.
