Is this statement correct?

Stream cross sections are drawn from left to right, looking downstream.

That's correct if it's how your legend or section label says....

That's how I've always seen it and how I've done them. Stationing for streams begins with 0+00 upstream increasing as you go downstream, and the cross-sections move like you read, left to right. The banks are defined by looking downstream, left and right.

I did six miles completely opposite.  Live and learn.

Just hold the drawings up to the Sun and look at them from the back.

@brad-ott 

If you haven't submitted or signed them yet, consider the mirror command, and the mirrtext setting.....

Had to do that in 1987 with some architect drawings on a clock tower in a strip mall.  They drew one tower and just noted that the other was a mirror image.

You should have seen how bowed out of place that steel was at thirty feet up!

Seemingly small comments and tips like this make this site so valuable.  Made us look good for a new client, without redoing 40-hours of drafting.  My thank you $ note to Wendell whenever I do send it, will be woefully inadequate, as usual.

Thank you, too @learner.

I believe that FEMA cross sections begin at the confluence of the steams as 0+00 and increase as you go upstream.  At least that's the way I remember it.  It has been a while since I reviewed sections though.

@andy-bruner yeah, we were told to start stationing 0+00 at downstream confluence where the ditch meets the creek and run stationing upstream from there.  But draw sections from the viewpoint perspective looking downstream.  This last bit was counter-intuitive for me.

It took 40 hours to draw cross sections? 😯
