你好@binabina,I J乌斯季想,当你在2D多边形使用挤出机,挤出你与他们的Z值,而不是添加到具体的离地高度。在现实中,你的建筑可能没有他们在z = 0的基础,但位于不同的高度。因此,为了得到正确的模型,你首先要获得每个2D的基础建设高度多边形(例如从DEM),然后挤压它们。
Thank you!
What if I dont have any DEM?And what exactly is the minimum and maximum z value?
Do you maybe know how i could put on a roof on my buildings after the extruder?
你的问题让我想起了这篇文章的2D到3D的简单模式:拉伸建筑物轮廓这可能是有帮助的检查,因为它也打在挤出2D多边形3D建筑物的话题。它示出了使用的一个例子挤出机变压器,该变压器@takashi建议。
如果您需要设置为还没有高度信息大厦任意默认的高度,你很可能设置使用缺少的属性和默认值AttributeManager之前通过挤出机运行它。请务必设置属性之前过滤掉不高的建筑物,所以它不会取代合法建筑物高度。你可以做一个测试器过滤的过程。
希望那有所帮助!
Thank you.
The AttributeManager did not work for me, i tried do choose a default value for those which are empty (tester worked) but he did not but values inside
hmm, can you share what your workspace looks like, perhaps with a screenshot similar to jonas_nelson's?I was imagining a Tester > AttributeManager to set a height attribute with a default value > Extruder to extrude these polygons to the default height by the attribute created in the AttributeManager.
This is my workbench and attribute manager..maybe my attribute manager has wrong setting?The attribute where u want to add values is calculated_height
