Profiling a Set of Points

I'm rehashing this one because a user asked me if it was possible to create a profile from a feature line.

I must give credit where credit is due. My good friend, Phillip Lynch, showed me this cool feature.

Scenario: so you’ve been given a set of points in line and have been asked to generate a profile from those points only. You don’t have an existing surface, nor do you need one. All you need is the profile of just the points.

Problem: you cannot create a profile without first sampling an existing ground surface.

Problem solved. . .

First, generate a feature line from those points. This can be done with a 3DPOLY that you connect from node to node and then converting the 3DPOLY to a feature line or by manually drawing a feature line from node to node. The node object snap must be used to absorb the point elevation:

Then select the feature line to active the context sensitive ribbon. In the ribbon you’ll find the quick profile tool:

In the “Create Quick Profiles” dialog box set your styles as desired:

Drop your profile anywhere on the screen. Now remember this is a quick profile, which means that if you save your drawing, close it, and return it will not be there when you get back. This is just a temporary profile:

But I want to make this a permanent feature in my drawing. To do this head over to the “Output” tab and find the “Export to LandXML” button:

In the “Export to LandXML” dialog box find the “Pick from drawing” button near the bottom of the box:

At the command line you will be prompted to select the objects to export. Select the profile (not the profile view):

Back in the “Export to LandXML” dialog box, click OK.

Save the XML file do a desired location on your system.

Save your drawing and the profile and profile view disappear.

Now navigate to the “Insert” tab and find the “LandXML” button:

Navigate to the saved XML file.

In the “Import LandXML” dialog box you’ll see that the profile is ready to be inserted:

However, when the importation is complete you will not see a profile in your drawing. You will see an alignment overlaid on your feature line:

Navigate to the prospector and you’ll see that you’ll have that alignment in your list. You will also see the profile in your list, but no profile view:

All you have to do at this point is import the profile view. Navigate to the “Home” tab and select “Profile View” > “Create Profile View”:

Go through the “Create Profile View” wizard and set your settings to your desire, then select the “Create Profile View” button and place the profile view anywhere you want in your drawing.

This profile and profile view are now a permanent part of your drawing.
