I'm trying to determine a way of color banding my point files so that different ranges of elevations are visually represented by different colors. See example below that I believe was done with a different software program.
You could do it using Lord Hailey's method, of course.
If you don't know about / don't want to learn about / don't have time to learn about expressions, probably what I would do is pop your points into a spreadsheet editor, like Excel, and sort and break them into seperate individual files according to whatever pattern you are desiring, and then add each file as a seperate Point Group in the drawing. You can then control the various Point Groups to display more how you want them.
Of course, for sheer CAD brilliance and impressing the ladies, Lord Hailey's solution is certainly flashier and more manly.
That's what I would do, anyway.
No need to take the points through Excel. You can include points in a point group based on their elevation.
Which is precisely what I did to come up with the image I posted. Took about 3 minutes to setup the label styles and create the point groups. These could then be saved to a DWT for use in future drawings.
You could even skip the point groups. Open the point editor, sort by elevation, select a group of points and assign the first label style. Select points in the next elevation range and assign the second style etc.
Jeff - What do the Child Styles involve - never been very sure and hence never use them??
I'm working on a similar task at the moment and I set my point styles to Layer 0 and Colour to ByBlock and in points editor I just select the relevant points and assign the layer as required (the layer has the correct colour)
For this quick example I just created 4 child styles of the ElevationOnly label style, giving each one a name of "Elevation Only - 92", "Elevation Only - 93", etc. Then I changed the text component color to the color I desired for that range.
Using Child Styles insures that if the Parent style changes, other than the properties specifically changed in the child styles, so, too, will the children.
And by using the Point Groups it all stays dynamic.
Thanks Jeff - I'll look more at child styles I think
