I'm having issues making the curve linework code BC and EC work.  As I understand if I start a line with a code of 'EP BC' and follow it with any number of 'EP' codes and finally end with 'EP EC' it should create a figure with a curve drawn through each point.  Similiar to the pline fit command.  This is not happening.  I am getting the curve drawn through the first three points, then straight lines connecting the rest.  Any suggestions?

Just curious on what your edge of concrete code iis, if EC, might need to switch end curve in linework code set. Since you would have edge of concrete and end curve being the same. We use PC and PT for curve linework.

I think your understanding of it might be the problem here.   I read it as only accepting 3 points for a simple curve code.

You may need to use OC on the intermediate curve shots. Last item on the Linework Code Set.

No and No.  You can use a BC code then as many figure names (ie: EB) as you like, then end with an EC.  I don't know why, but I changed the BC and EC code to PC and PT as suggested and it works great.  FYI, I am using number figure names (31,32,33... is concrete, 41,42...is gravel).  I am now having issues with it drawing lines between all my tree points.  Not sure how to correct this.  Trees are coded 410 12 (where 410 is code for Oak and 12 is caliper in inches).  I'm sure the line issue is because C3D sees the 410 as an iteration of the gravel code.  Any suggestions on this one?

Is it just stringing the 12" trees together? If so my guess would be that you have (12) defined as a figure in your figure prefix database.

Since you have 41 as gravel, 410 is probably being seen as gravel since it begins with 41. These are called figure "prefixes" for a reason. It's like having TR for trees and TRAIL. Since they both begin with TR you may run into problems.

Yes Matt, I think this is exactly what is happening.  But what changes do I need to make to fix it?  Our field crews use a data collector that has a numeric pad (it's an older Trimble CU) hence the use of the numeric code system.  Typing letters involves several extra key clicks for each letter.
