Automatically calculate plot dia after slope angle

Dear user,
If your survey has an attribute with the plot radius called "plot_radius" and another one with the slope angle (in degrees) called "slope_angle", the expression you typed will work as it is.
Create a new read-only attribute, called for example "plot_radius_adjusted" and use that expression as a default value expression (define it using the "Advanced" expression editor), following these steps:

• Create a new decimal attribute and mark it as read-only:

• In the expression editor that appears, click on the "Advanced" button on the top right corner:

• Copy and paste the expression in the text input:

• Apply the changes and if the expression is correct, the result should be this one:

Many thanks,
