“I've created a Site Model, but now Vectorworks is running slowly?”
When importing a DWG or a Survey, it's possible that there could be more points than needed for most site models. This can result in some slowness, especially if we're placing in a lot of Site Modifiers. One thing worth checking is the Source Data of the Site Model; we can get into that by right clicking on the Site Model and then choosing to "Recreate from Source Data".
Going into a Top/Plan view and selecting the Reshape tool will give you a better view on how many points the Site Model is calculating. For example, this Site Model is calculating the site with 1,545 points; this can start to get even larger with additional Site Modifiers and other changes.
We can trim down the amount of points with Modify > Drafting Aids > Simplify Polys. You can see more information on the entire command and details here:
But for this example I'm just going to use a Minimum Distance of 2', which will only allow a point along those source lines every 2'.
This site model now only has 149 points, which is less than 10% the amount of data the previous Site Model had to process. You can see the differences in the contours and 3D models below (left is original, right is updated):
It's still keeping all the key points of the previous contours, so your calculations will be mostly the same. You can always experiment with this and reduce the Minimum Distance farther if you're trying to stay more true to the original source, but it's up to you to determine the best simplification for your Site Model.
