Using the Trace command

When I use a default polygon like Border, Default, I can use the Trace command. However, the simple drawing commands don't give me that choice. Is this intended behaviour?

The reason I want to use them is that a border (In Mercator style, at least) is a smooth polygon, and it doesn't go into the corners of my fractalised landmasses when I trace the coastline. If someone can tell me how to solve that instead, it would preclude my needing the other solution. Right now, I'm adding extra nodes at each corner, but that's not very efficient.

    Yes. Only the advanced tools have the trace function.

    To solve your problem, I believe editing the drawing tool you are using (or better yet, make a copy of it and edit the copy), and have it use another shape should help.

    - Open the drawing tools dialog
    - Click Advanced
    - Select the desired tool in the list
    - Hit 'New'. This will create a copy of the currently selected tool under a new name
    - Select the new tool.
    - Select the polygon shape in the "Draw Methods" section. Each method has it's own set of options that can be accessed by clicking "Options" after selecting the draw method
    - Hit save to save the new tool.

    You now have an exact copy of an existing drawing tool, using another shape.

    Will "trace" work in CC2/CC2 Pro? I try to use it, and I am given a negative response.

    Thanks,

    What negative response? IIRC the trace function of the drawing tools works the same in CC3 as in CC2 Pro.

    What about CC2? It should not happen, but when the key is pressed, I get a response referencing CC2 and not being able to do this command (and I upgraded to CC2 Pro a long time ago). What is the problem?

    Thank you,

    CC2 does not have drawing tools and therefore no Trace option to use. Still not sure what command you are actually using.

    If you get an error message referencing "CC2", that does not mean you are using CC2 though, the message popups tend to still have CC2 in the title, no matter which program you are actually in.

    Is there a "trace" function for CC2 Pro? I have seen "trace" show up in other contexts (like adding to an entity). Is there a reference for "trace"? How is "TRACE" supposed to be used? I have a mad idea about irregular walls...

    Sincerely,

    Trace is part of the drawing tools. Keep an eye on the command line: If you start a drawing tool, you'll notice the "T-Trace" option when it is available. I can't check for CC2 Pro right now, but tracing should be possible with it too, as it uses drawing tools.

    To actually trace something, hit "T", the click the entity to trace. Click the start point for the trace, then the endpoint. Note that with entities with many nodes (most notably fractalized polygons), tracing can be a bit sluggish. Be patient.

    Does Trace work on all lines? When I had tried to use it (when I'm not confusing it with "Outline" - Sorry Ralf!)it would not recognize the point I chose to start this whole business. Is there a problem with an end point?

    Sincerely,

    You can trace a line, but always only one at a time ... that makes it very inconvenient. You'd normally use trace on a path or polygon (smooth, straight or fractal does not matter). Not sure what you mean by "problem with an end point".

    First,

    Ralf: The "trace" function is pretty unreliable for me. I attempt to choose a starting point (probably using endpoint) to ensure that the function begins smoothly at the starting point) and I have a problem getting the program to recognize the beginning point of the trace.

    Is the program going around and around (looping) an entity? What buttons would interfere with the smooth use of the trace function? I want to be sure that there are no errant buttons pressed and confusing the program. Is the "trace" function useless for a fractalized line (lots of little lines) or not? Can they be united short of a multipoly for the purpose of tracing?

    Thanks for your attention,

    I use Multipoly instead of trace. I use the previous map/scan as a guide. My eyes just don't handle lots of small detail.

    Sorpaw, I'm adding a page from the very first Annual mapping guide to this post, that explains the process of tracing.

    As to you questions:

    1. The program is not looping the entity. But it redraws the tracing line each time you move the mouse and on complex entities this takes a moment. That's why it might seems slow and a bit awkward when you trace complex entities.

    2. As with any other commands in CC3, you can use some other commands within Trace and others you can't. Zooms and Redraw are things oyu can always do in between, but if you start an edition command like Move, Erase, etc. the current command (the trace) will be interrupted.

    3. No, trace can be used fine on a fractalized entity, but it may be slow. See above.

    4. You need to differentiate between line entities and path entities here. A line is just a single stretch between two points. A path is made out of lots of different nodes connected by straight sections. If you explode a path, you get several lines. If you have multiple lines you can't trace them in one go, only ever one at a time. But if you have one path, it can be traced just fine. You can see whether a coastline (or whatever) on ypour map is made out of multiple or a single entities, by selecting it for any command. The command line shows how many entities you have selected.

    You CAN make a series of lines into a path, as log as they are all connected (endpoints touching each other): Right-click the Explode button and choose "Line to Path" to do so.
