If it is not our survey work we ask for an xml file of the surface and 2d linework and text for the property and topographic surveys. We do not request or need their point objects specifically if we get the surface, syms and text labels.
That's nice, I was commenting for others sake who use these forums as a reference to finding solutions for potential issues.
The focus should be on what your subject line indicates, not a sub-topic that was introduced halfway though. Partially my fault for commenting on other's comments vs. sticking to what my main question is, and that's the visibility of points and point labels through and XREF. Maybe it's best to open a new thread since we're off on a major tangent.
As many have stated, get your DWT setup the way you want it to function. During your contract negotiations with the surveyor indicate in writing what they need to provide. If they do not provide the product per the contract send it back. After all, they are working for you. You should not have to manipulate the data in any way beyond cosmetic layering changes so the survey data shows up correctly in your design product.
With that said, we have our own in house surveying (me) that sets up our survey data, labels, styles, etc..... In civil3d we have a text layer and a point layer for each description code this allows us to freeze the text or symbols independently of each other.
My 2 cents....
I'm not exactly sure how extensive your surveys are.
If you're dealing with an existing site survey, with above and below ground locates, combined with a road survey... You're talking upwards of at least a 150 possible point descriptions and having a layer for both "point-description" and "point label-description" is not going to happen. High probability your drawing file would even open at that point.
Off topic, but that's precisely the type of work we do, our DWT has 517 layers all with appropriate filters to quickly turn things off and on. You may have misunderstood.....we have a separate "SYMB" layer for each code that requies a symbol. This is controlled by the description key set and then a separate "TEXT" layer that contains the point number, elevation and code' which is controlled by the label style. It works just fine and allows much flexibility in displaying points, markers, symbols and text. Working on a site project right now with over 7000 surveyed points.
