C3D - point to point inverse

nope

Do you want a 3D inverse or plane inverse? If you want Plane (2D) go to the command line at the bottom and right click pick options and then drafting tab - check the box for replace Z value with current value. This will have you measure in 2D. You can then type the 'DI' command and pick the nodes of the two points you want. It will display the distance between them. The alternative is to draw a line between them using 'L' command and then 'LIST' the line.

Also, you can draw a line in between the two points and label it with bearing and distance using the annotate tab and add label. Just select the correct label type. (Hopefully one is set up in the drawing) if not you'll have to create one, which is kind of complicated especially if you're not familiar with C3D.

try typing in "COGOEDITOR" at the command line

> Is there an easy way I can get the inverse dist and bearing from the drawing?
No. And that is more than a bit perplexing. It is possible, but so convoluted that you would never do it even if it was thoroughly explained, so I won't.

Instead, draw a line between the points. Then in the "Analyse" ribbon menu, in the "Inquiry" section, pick the icon that looks like a 90°arc with 3 nodes. It's is called "Line and arc information". Then pick on the line (or arc, as the case may be). You will get your inverse information.

Alternatively you can activate that command by entering "CGLIST" at the command line.

yea really.....I had to double check to make sure there wasn't an easy way, but I can't find one. Why do they make it so difficult?

> Why do they make it so difficult?
Softdesk and LDD where equally convoluted with this one simple function. They made no effort to improve it in 20 years. They just don't get it.

2d inverse is 'CGCDIST', but it does not output a bearing 🙁
Usually i use a labelled polyline for a 2d dist and bearing.

I'm not sure what the difficulty is here. Open the Inquiry tool, choose Point inverse and pick two cogo points. Seems pretty simple to me.

Yes, there is a way.

On the "Analyze" pulldown menue, go to the "Inquiry" menu. In it you will see what is called the "Inquiry Tool".

Once opened, the Inquiry Tool has several options of inquiry. One is point inverse. Enter your point #'s or do a screen pick of the point entity by clicking on the boxes with the ...'s next to the point 1 number, point 2 number entries. You'll get an automatic result of the bearing and horizontal distance.

If you want the 3d distance then you can do a point to point inverse using the "Measuregeom" command.

Thanks for the replies.
I am looking for a way to get 2D distances easily.
I use a program called Softdesk8 on autocad R14 (i know, dont laugh, its very old).
there is a stakeout routine that will give the 2D distance from a given point to all points within a given radius. there is also a command for inverse points which give the bearing and distance. it gives the option of typing the point number or picking the point.
I was hoping to find something like this in C3D.

In softdesk I also like being able to find where a point is in the drawing by starting the line command and when you give it the first point number a line will appear from the mouse cursor to the point.

I think I like this C3D, but it is fairly heavy and is not suited to casual use.

As a few have pointed out, you can use the inquiry tool which i personally find to be a bit cumbersome for everyday quick inverse checks. I find it useful when I just want to know the inverse between XXX and XXX without having to zoom around in the dwg to find it and click it, etc....

This is what I do: Make sure all your points come in with zero elevation(this is set in your point style, maker sure your units are set to surveyor bearings in the DDUnits command, make sure you have 'node' osnap on and the simply use the Distance command (which I have shortcut to be just 'd') then pick your two points and you have exactly what you need. My templates are all setup with these settings so its a really simple process. The one gripe I do have is that you can't select the point number, elevation or description portion of the point (like you could in LDD). You must be sure you select the point to ensure the 'node' is selected.

this looks like it will do what I want

Thank you. I think the "ANALYZE -> inquiry -> inquiry tool -> point inverse " command will do what I need.
I am a bit more familiar with softdesk so I find their routine easier.

The easiest way I have found is the simple distance command:"DI"
Set your options to current Z value

This is an inverse 315 to 316.

You can do it with point numbers if you want the wrong answer;

> there is a stakeout routine that will give the 2D distance from a given point to all points within a given radius.

That routine is also available in Civil3d. It's one of the report options available in the Toolbox tab on the Toolspace.

But Carlson Survey and install it on Civil 3d, the best money you'll spend for working with points.

I have two lisp routines that work very easy.

2DD for 2D distances and bearing. Invoke command pick two points.

3DD for 3D distances and bearing. Invoke command pick two points.

All command line.

C3D is not tool friendly for simple cogo routines.

To punch in deeds I use a lisp routine LBD- pick start point and roll. Simple

The ribbon sticks and drop down menus stink.

Smartdraft add-ons for C3D gotchas

Point inverse and a few other gotchas are solved with the addition of Smartdraft from John Cooke at Civil Training, LLC. I think he has a website named Smartdraft.

After using C3D for 8 months, I can now say " I'll still take Carlson any day"

Thanks.....didn't know that was in there. I have the inquiry tool as a shortcut tool palette but it doesn't have all the same bells and whistles as if you open it that way.
