Created new alignment but no chainages

[dgc74]

I created a new alignment based on a survey topo. The first half of the alignment shows the sections/chainages but the second half does not. My alignment should be line, curve, line, line, curve, line, line, curve, line but when I check the design editor, it only shows the 5 elements. When I check the sub entity it appears some are not assigned numbers which have generated a warning symbol.

Why are the last 4 entities not recognized?

If those segments are indeed part of the alignment yet the chainage stops, they are not connected (ther's a gap), or one of the objects is drawn in the wrong direction.  Turn on the arrow component in the alignment style and you should see the arrows pointing all up-chainage.  if there is one that isn't, there's your problem.

Aside from what Matt suggests, is it possible you drew those unlinked pieces with a different alignment set current? If so you won't be able to connect those pieces to your alignment. To verify, check the name of the alignment in the properties of the pieces.

you please remember , this is a small idea , when ever you design the alignments on topos, you must use the polyline only , you never use the line command ....dontworry......:smileyhappy :

Not true. You can create successful alignments from lines and arcs, I do it all the time.

Thats the wrong way to create the chainge to alignments.

For example: If 1km length alignment( ie.,1000m) having chainage, the
alignment having some curves not a strightline, then how did you create the
chainage along the alignment at a time.If it is possible but taking long
time to create the chainage to alignment but small mistakes are coming.
ok thanking you sir,


with regards

I am not sure what you mean by that, but the fact remains that you can create alignments from lines and arcs in Civil 3D, and there is nothing wrong with doing so.

What are these "small mistakes"? Thanks.

In this case I think in not reading the manual before using the software.
I think that he is not using a label but manually adding this information.

IVS2112 NB:

Chainage (labels) are automatically created based on the start point of the alignment or selected zero marker.

You can upset the balance by adding user chainages and overriding the values forward or back wards.
