About the coordinate system of CAESAR II

The CAESAR II software does use the coordinate system of Descartes' right-hand screw rule by default, but you can change the coordinate system to the left-hand screw rule through settings. The specific setting method is as follows: 1. Open the CAESAR II software and select the "Options" option in the main menu. 2. In the pop-up options dialog box, select the "Modeling" tab. 3. In the "Coordinates" option, change the "Coordinate System" option to "Left-Handed Helical". 4. Click the "OK" button to save the changes. At this time, you can use the coordinate system of the left-hand spiral rule for modeling and analysis. It should be noted that if the project requires the use of a coordinate system using the left-hand spiral rule, this coordinate system must always be used in modeling and analysis, otherwise it may lead to incorrect calculation results. .

Sorry, I didn’t find the modeling option in options. I am using 2019. Does this function only exist in higher versions?

Sorry, my answer is wrong. There is no Modeling option in the CAESAR II 2019 version, but it has been replaced by the Setup option. In this version, you can change the coordinate system to the left-hand spiral rule by following the steps below: 1. Open CAESAR II 2019 and enter the project. 2. Select the "Setup" option in the main menu. 3. Select the "Coordinates" tab in the pop-up options dialog box. 4. Select the "Left-Handed Helical" option in the "Coordinate System" option. 5. Click the "OK" button to save changes. At this point, the coordinate system of the left-hand spiral rule can be used for modeling and analysis. It should be noted that if the project requires the use of a coordinate system using the left-hand spiral rule, this coordinate system must always be used in modeling and analysis, otherwise it may lead to incorrect calculation results. .

I saw the word home>setup in the help, but there is no such option in 2019. Can you take a screenshot to see if you want to change the icon?

Hi friends, if you are using a lower version that can implement the coordinate system of the left-hand spiral rule, please take a screenshot of the modified coordinate system. I will find a lower version later and try to change it. It is estimated that the later version of CAESAR II has modified this operation, and the txt file may need to be modified, maybe this function can be achieved.

The project's coordinates are different from the right-hand criterion, so the software cannot be set to this coordinate system. It is recommended that the project verify whether the coordinate system is correct. Generally, mechanics software uses the right-hand criterion. The software can only set the coordinates in the following image style.
