Problem with merge tool in 3D

MatusKolenka — Thu, 26 Oct 2023 18:54:12 GMT

I am working on 3D map of the city. All buildings are visualized from polygons. My task is to connect polygons into buildings. I tried it with the "Merge" tool, but i have big issues with it.
Firstly,as you can see on the photo, after merging polygons, the whole shape is distorted or even completly disapears.
Secondly, as i try to merge for example wall with roof, error "cannot merge overlaping polygons with differing z values.

I will be very grateful for your time and advices

Best regards

Hi!

Try to find the field that has/have different length size, via the attribute table. The polygon those have been displayed blue in your map means that the size of its length does not match the other polygon.

Best,

my whole attribute table looks like this:

Hi !

I use these steps, try it, i hope it will work for you.

Don't worry about attribute and property, if these steps worked for you.

Good Luck

Hi!

You are most welcome, what is the problem? Please send me a screenshot where you faced a problem. Your attribute table does not have Height for the building. If you want to merge polygon with polygon, there is another method. Your attribute table as you shown above does not have height, you can fill it with the elevation height of your 3D attribute table via geoprocessing tool.

what is this another method you are talking about?

Hi!

Please do not think about merging (another method), you have already in the final step to connect your 2D shp with 3D Scene.

Good luck

Hi!

1.Convert you 2D map to 3D as I shown on my screenshots.

2. Select height from elevation menu again, and make sure it works well.

3. Select View tab and then link views as shown below.

As soon as you done this process your 2D and 3D connected together.

I manually created an attribute field for height and then extruded it, it works well. Below is a 3D view of Košice Slovakia.

Your attribute table already has height for the building.

Good luck

After following your steps, all my polygons have 4 vertices. But in my case, i need also polygons with only 3 vertices (such as roofs). Also, i tried to generate height with geoprocessing tool "Generate elevation bands", but unfortunetly, this tool its not licensed to me.

But i am trying different strategy now. Instead of working with polygons, i visualized all my geometry with points, where i can calculate height. I can merge points into specific buidlings, but i do not know, how to create polygons from points.

Thank you for your time and advices

Hi!

Here are the methods to convert polygon to points and points to polygon:

1. Convert polygon to points

2. Convert points to polygon.

Best,
