    Do we need to convert a point file to a FBK in 2010? I've seen some of the upgrades in coding and have cautious optimism.

    Hi Freddy,

    The short answer: No, you don't have to convert the point file to a fieldbook. For example, if you have a text file with the following lines:

    1,5000,5000,0.00,B BC1
    2,5000,6000,0.00,BC1
    3,6000,6000,0.00,BC1

    And simply import the survey data as a point file (PNEZD Comma Delimited), the data will be properly read, and the linework will be properly drawn.

    The long answer: This is a significant step forward. In the past, it wasn't readily understood that you could run SVLINK and convert this "User-defined ASCII" file into an "Autodesk-Softdesk FBK with Linework." When the FBK was imported, the linework would be drawn properly. But with the advancements in C3D 2010, this is no longer necessary.

    You can now create survey data by importing a field book file, a landxml file, a point file (as above), or points from a drawing. The "Linework Code Set" holds the key to the linework creation tools, and the linework is always created based upon the description of the point.

    Thanks Scott. Does this mean my point description will now say B TC1? If I use the FBK file can I get my standard description of TC1?

    Hope things are going well for ya, let me know if I can do anything.

    You can filter down the descriptions using description keys.

    Actually, using your example [b]TC1[/b] above, as long as you have a figure prefix TC in your Figure Prefix Database, you don't need the "B" or "BEG" or anything else for that matter, period. Civil 3D will begin a figure automatically if it finds the figure prefix in the database.

    First shot on TC1, nothing happens. Next shot on TC2, nothing happens. Third shot on TC1 - line is automatically drawn. You can even use the / as an "escape" during a sequence of shots - this would allow you take shots out of numerical order and still see correct linework. In the following example, i shot the midpoint of a curve first, then the PC, then the PT. But was still able to create an arc at the curb return.

    15,5374.9371,5320.2997,0.00,BOC3 / [i](shoot BOC3 and escape - do not start a figure)[/i]
    16,5374.9371,5368.6031,0.00,BOC3 H0.5 H2 RPN15 BC [i](shoot BOC3 - this will start a figure, then recall point 15 for the midpoint of an arc)[/i]

    17,5390.9371,5368.6031,0.00,CL1
    18,5406.9371,5368.6031,0.00,BOC1
    19,5369.0793,5262.4419,0.00,BOC2
    20,5369.0793,5306.1576,0.00,BOC3 [i](finally the last shot on the curb return)[/i]
    21,5354.9371,5300.2997,0.00,BOC3 ([i]creates a line tangent to the curb return)[/i]
    22,5354.9371,5284.2997,0.00,CL2 CPN12

    So how cool is it that you don't have to take all three points on a curve shots in a row like the old LDD format? WTG Autodesk and Rob Todd!!!

    I hear ya! This will most definitely enable us to use Civil 3D for our survey dept.
