Currently not found yet, secondary correction of angle is needed in this situation

When developing based on face family placement, running the program found that positions of parking spaces all changed, only origin position can be aligned
Error placement
Through troubleshooting, suspected related to vector of slab itself, ==i.e. first line of slab profile==. Through analyzing different slabs in four directions, can find that foundation preview position of face-based family is continuously changing, and keeping parallel with vector, as shown below:
Image Description
Vectors of three slabs
Slabs of same thickness type and without slope, only first drawn spline is different. Found that initial state of each parking space is changing. If developing without considering this issue, ==will cause position change on planar sloped slab or other situation slabs.== Of course this change can be controlled by space bar, but it violates premise of development function reducing work loss.
But this conjecture is just my hypothesis, still need to verify with official.

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.
