Revit二次开发结构柱Solid.Faces取值出现问题
仅提供中文版本
由于项目需要，需要对结构柱顶面进行取值。在对顶面取值中发现edge长度取值错误，通过lookup发现取出顶面含有六条边:(
作为一个矩形柱是不可能的事情。但是没有思考清楚问什么会出现多取两个值的情况，而且里面边长只有一个符合柱本身需求。
第一次取值使用的是familyinstance情况下直接取geometry，发现错误后通过先对symbol取值再取顶面值会正确。初步想法是由于顶面与其他构件连接造成的geometry取值错误。

QT+ CLion + Revit 问题汇总
ui因为一直想实现QT+CLion+Revit的开发路径，所以从头开始学习QT与C++，在这里记录一下QT遇到的问题及后续的问题。如果开发周期不足估计会用一两周爆肝出来，随时会断更。 目前的思路是C++创建dll，在dll里面编写QT界面，之后用C++ Revit 的API接口实现整个步骤。中间需要用到sqlite3的数据库组件，目前就想到这么多。现在已经实现c++读取sqlite3并完成数据接口。 由于项目进度，之前为了实现cpp+QT耽误了太多时间，所以国庆肝了三天完成整个程序，能够将整个数据库的结构模型创建在revit中，在思路已经清晰的情况下，写起来速度确实快了很多，用完cpp再用c#发现c#的继承还挺好用的，测试一下整个项目之后再继续修复这个项目。下面是所有楼板的成果，21层的框架结构预估时间在十分钟以内可以完成，我是分块测试没有集中测试，明天去公司测试一下。 @[toc] 2021/09/14SQLite3带有中文路径的字符串转码12345678910111213141516171819202122232425262728293031323334...

WCF Use Console to Drive Revit
Currently doing family library project, already made WPF interface but because it was WPF project at start, intermediate interaction operations need to be implemented in Revit, thinking of driving Revit through WPF thereby implementing communication between two windows. One way is generic, implemented using external event, this path is relatively easyAnother way is when reading jimmy‘s blog found a case, using WCF as connection to drive two independent programs.

WPF Revit Secondary Development Using Tree Structure to Display Revit Data
During function development, it is necessary to use attribute structures to make the Revit data structure itself clearer. When writing code, the MVVM pattern was adopted, and data collection and organization were completed in the backend.
