One of the new and cool features introduced this year are the additions to the Survey functionality. Survey Query tool can be used to filter points and figures from Survey database by their properties. Since survey data is stored externally in survey database, it can be brought or referenced into a drawing-we all know that by now. Survey Queries now allow us to filter by any of the survey properties listed in either general or extended properties defined by user defined properties or brought in via LandXML.
One other thing you may notice when building a Survey query is the Survey ribbon that allows us to not only create new queries but to also insert them into the drawing or add them to the surface. It looks like this.
In survey tab you will see a new node “Survey Queries”, right-clicking on it will bring you to the Survey Query Builder.There you can name your query, add criteria and even preview it or save the query. So let’s see how to create one simple query out of points with description containing SDWK value. For lack of better idea, let’s say our goal is to filter all points defining our sidewalks.
As mentioned earlier, we can select any property from points and figures and build query from them. In this example I used code SDWK. So Property is set to Description, Operator: Contains and Value as SDWK. Notice other available options as well as what happens if you add one condition-the next row is populated allowing you to further narrow down your condition with AND and OR. If you select Display in Editor, program will display your results in Panorama. You may also choose to Save Query (it will show up in Survey tab) or click on Preview in Drawing. Notice little glyph (red box) on the image-this will indicates that you are in preview mode.
Off course, if you like what you see, you can save it or edit it in this Panorama.
Finally, you may wanted to add your queries to your surface - you can! Whether you queried your Survey database for points of Figures you can add them to your surface. One thing to note here is that the queries exist in the Survey database and not your drawing.
That is all I had for now, but if you would like to get little demonstration of this feature click on this link.
Cool stuff and easy to use-just what we want!
