A friend in the industry asked me to write a plug-in to quickly create elevation.[TransactionAttribute (Autodesk. Revit. Attributes. TransactionMode.

Revit does not know why there is a strange rule that it is impossible to draw a line of length less than 0.8mm in length. (0.8mm equals 32 of one inch). Cause a lot of small short lines cannot be drawn.In light steel thin-walled member, its thickness is only 0.5, some 0.7, can not be drawn. This brings some limitations to Revit's work.Here is a programmatic way to create less than 0.8mm, and its usage is a bit hard to think of.First we create a long l

How does Word 2010 's formula convert to a MathType formula? The following is an introduction to how Word formulas are converted to MathType formulas. Since most computer systems today are 64-bit systems, the problem is that they appear on 64-bit operating systems, 32-bit Office 2010. The folder for Office 2010 under this system is C:\Program Files (x86) \microsoft Office\office14, note that this is a dir

POI reads cell information and cell formulas, and poi reads cell formulas. Java EXCEL tools are generally POI and JXL. I am a loyal fan of POI. (In fact, I have never used JXL ). Most of the current excel versions are later than 07, so I usually use POI on the basis of 07. Cells have Styles, values, and value types. Style copy is encapsulated into a function: Public XSSFCellStyle cloneAllCellStyle (XSSFCell

Note: This article will not mention the details of the project, but will look at this issue from a general or general perspective .......... Yesterday, the day before yesterday, I went on a business trip and made a small project to help others improve the accuracy of their existing Approximation Formulas... in fact, in practice, the approximate formula is used a lot, because the computer will only perform the +-*/operation, and the essence is only +.
