Reverse distances and bearings

[Arty]

Hi,

 

I'm working with siteplans and have a lot of distances and bearings in my drawing. Sometimes i need to reverse them. Is there a command in AutoCAD 2012 where you can reverse a hole heap of distances and bearings all at once? Mirror make them up side down... I want them to swop sides of the line they refer to.

If there two words BRG DIST 100d57'23" 123.457 easy just find space and rewrite as dist brg using a lisp. Lee-Mac has a find character lisp on his web site as a start point. While I think about it sure someone will post soloution. Going home now.

So all you want to do is change the POSITION of the bearing and distance not actually reverse it (ex. - a NW bearing becomes a SE bearing). Is that right?

I believe the OP wants to do the second thing. That's what s/he means by swapping the ends. It's fairly common in surveying.

 

The solution will depend on whether the edges are independent polylines or components of parcel objects.

Sorry Cyber but I do not get that same impression because the OP goes on to say...

 

"Mirror make them up side down... I want them to swop (swap) sides of the line..."

Perhaps the OP could post a picture so we can see what is required.

Hey guys and thanks for trying to help. Sorry if I made you confused... Remark is right. I want to change the positions of the bearing and the distance where the bearing will change direction. I have now moved them and changed them one by one, so all is good, but for future reference it would be great to know if there is a command where you can make them change sides of the line and automatically change direction...

 

What I am doing is: In my project I have a long road through the site plan with smaller lots on eather side. The bearings should be on the road but they are on the lots at the moment. It's many bearings to move out to the road and to have a command switching this for you yould be nice!

 

In attached jpg there is a picture of the road and all bearings and distances in that section. Hope you get a better idea of what I'm after.

That's some strange road layout if all you are using is straight line segments to define what should really be a curve.

 

What you need is Lee Mac's Flip Text lisp routine which can be found in this thread. http://www.cadtutor.net/forum/showthread.php?46627-Flip-Multiple-Texts-180-Degrees

Well I don't know what's strange or not, this is how my company do it... I've been there 6 weeks so I don't take any responsibility for how thay have set up their work, but I'd like to make my work smoother and faster so thanks for your help. Not sure what a lisp routine is...?

can you explain so i know what you mean I should be doing? Thanks!

A lisp routine is a program that is run inside of AutoCAD. You can load the routine via the APPLOAD command. Once loaded you can run the command by typing FlipTxt at the command line. Follow the prompts.

[Arty]

Okay...I'm kinda green so not sure what I am looking for to load... I looked at the link you sent but not sure what to do with that code...

Heaps of folders poped up when I wrote APPLOAD in AutoCAD, not sure how to continue from there...

You have to copy the code from the link into your app (lisp or *.lsp files) folder(s) so you can see it after typing appload, then select it as the one to load and run.

A lot of those lines are probably cord bearings. When drawing a survey up, the cord bearings are the first chunk of data I look for when doing the curves. There are a bunch of curves with different radii one after the other on that road. It must be in Europe or South Asia, or maybe Florida. Lotsa little lakes down here to avoid.

 

I'm wondering why they are using headings instead of compass bearings. I have never seen a single land development drawing with a bearing greater than 90 deg., before. Maybe they will put in the NE SE SW & NW later?

 

I'm also wondering why I'm typing this in near darkness while my wife watches Dancing With the Stars right over there >>>>.

Thanks guys!

 

All done and loaded

Its normal practice here in AUS to go round in a circle so a 4 side lot would be BRG 0 90 180 270 it does though get confusing sometimes two parallel lines may be brg 0 other 180

[ReMark]

Maybe we need a short tutorial about what to do when one finds code posted on a forum like this and someone wishes to make use of it.

[eldon]

What would have been interesting is to have seen a picture of what the OP started with.

 

The picture of the result is not very informative as to the problem.

Normal, is it now?

Well, that's what comes from being upside down all the time. All yer heads are pointing south all day long and everybody knows North is Up.

 

Here in the US it's practice to try and keep North at the top of the page (which you probably do as well) and draw the parcel as it naturally sits on the ground starting at a point and proceding clockwise around the property. Each time the bearing hits 90, we change the compass point, NE to SE, for instance, and start going back down to 0 deg again. We are always going either primarily North or South with the degrees showing how far we are tilted away from North or South, in an Easterly or Westerly bearing.

 

I still have not figured out how to tell vanilla AutoCad I want to go clockwise. When I do it makes ALL my bearings backwards.

What? let her cook? Out of the question. never again. Have you ever seen nearly raw chicken come out of a slow cooker after 8 hours? I have. 'S awrite though. Cooking (at least not that kind) was not part of my selection criteria.
