Site Model

[BJS]

Is there an easy way to "sketch" out a model of a building site or lot? Most of what I read requires data from a surveyor and what I would like to do is simply place my building model onto a site that is approximately correct in 3D. It seems there must be a straightforward way to create a polygon and "lift" up areas with a higher grade etc. I don't need extreme precision here.

Thanks for any input.

You can use the grid method for creating a site model. Then you can just input elevation points from a grid overlaid on the survey.

Or you can lay out some 3D loci using spot elevations on the survey, and select those to create the site.

A quick and dirty way of creating a simple site model is:

- Draw the site shape with Nurbs Curve tool.

- Convert to a Nurbs Surface (Model/3D Powerpack menu).

- Set weight to 1 and change U and V vertice values to give you a reasonable mesh across the site.

- Use the 3D Reshape tool to adjust the locations and heights of individual vertices.

If you want an object that you can mould with control then you should use the DTM. It will produce a better result and can be manipulated more easily.
