PVcase is able to work with any sort of site survey or topography that is presented in a .DWG format and has an elevation parameter or Z coordinates.

If you as a client are having some sort of issues with your site survey not working properly - please contact us & we will make it applicable.

Generally the best topographical surveys are with densely filled terrain defining objects. Working on these topographies result in more accurate layouts and smoother park development. Below you can find a few examples of good and bad topographical surveys.

1. Height measurements or height numbers;

Good topographies - these topographies have clear and densely populated terrain indicating objects.

Bad topography - height measurement indications are scattered and filled with other numerical information on the same object.

2. Contour lines;

Good topographies - contour lines are densely populated and have the same distances between them.

Bad topographies - distances between contour lines are too large or don't have elevation properties and are scattered in various distances between each other.

3. Mixed topographies;

Some surveys consist of several different indicative objects, like contour lines and height measurements. These offer even more precision.

4. Point data cloud;

Basically every point data cloud is good as long as points have dimensional coordinates as a property. Sometimes data is in blocks therefore needs to be exploded for usage (example below).

After using Explode command in AutoCAD, point object appears with 2 attributes next to it.

5. 3D faces;

3D faces can also be read well as long as they have position properties.

Note: Some 3D faces are made into blocks, surfaces or polyface meshes, which need to be converted using AutoCAD command Explode.
