The LC/Envelope actions are manipulations of the calculated results applied for the Load Cases (LC) and the Envelopes superposition files (Sup), as management actions to create new files that will include the desired values. They're listed below and more information can be found at Help F1 or at RM Bridge Analyzer User Manual.

• LcInit - Initialize LC: Create a new load case with empty results or with factored results of an existing load case.
• LcAddLc - LC Added to another LC: Add the factored results of one given load case to a second load case.
• LcDel - Delete LC: erase an existing load case.
• LcClear - Clear the LC: Reset the load care results for certain elements and DOF
• LsInit: Initialize a new load set.
• LsDemo: Model element removal by writing definitions to an existing load set.
• LsCorB: Compensate for deformation after element removal (at element begin)
• LsCorE: Compensate for deformation after element removal (at element end)
• LsCamb: Fabrication shape - Include current displacements for position correction of elements to be newly activated.
• SupInit: Initialize a new superposition file with zero results or with factored results of an existing superposition file.
• SuppAddLc: Superimpose load case results to a superposition file by unconditionally adding the results.
• SuppAddSup: Superimpose envelope results to a superposition file by unconditionally adding the results.
• SupAndLc: Superimpose load case results to a superposition file by conditionally adding the results. New result values are added to existing minimum envelope values if they  are negative and existing maximum envelope values if they are positive
• SupAndSup: Superimpose envelope results to a superposition file by conditionally adding the results. New result values are added to existing minimum envelope values if they are negative and existing maximum envelope values if they are positive.
• SupAndXLc: Superimpose load case results to a superposition file by adding the results with the appropriately positive or negative sign to get the most unfavorable results.
• SupAndXSup: Superimpose envelope results to a superposition file by adding the results with the appropriately positive or negative sign to get the most unfavorable results.
• SupOrLc: Conditional replacement of the superposition file results by given load case results. Load case results replace existing minimum envelope values if they are smaller and existing maximum envelope values if they are greater.
• SupOrSup: Conditional replacement of the superposition file results by given load case results. Load case results replace existing minimum envelope values if they are smaller and existing maximum envelope values if they are greater.
• SupOrXLc: Conditional replacement of the superposition file results by given load case results with a positive or negative sign. The superposition rule SupOr is applied twice with the given load case results of both signs.
• SupOrXSup: Conditional replacement of the superposition file results by given envelope results with a positive or negative sign. The superposition rule SupOr is applied twice with the given envelope results of both signs.
• SupSqr: The squares of all values in the given envelope are calculated and stored to a given superposition file or rewritten to the source envelope if no superposition file is given. A factor may be applied.
• SupSqrt: The square roots of all values in the given envelope are calculated and stored to a given superposition file or rewritten to the source envelope if no superposition file is given. A factor may be applied.
• SupComb: Apply a combination table to calculate an envelope as the combination of factored load cases. The resulting envelope is often used for fiber stress checks (Action FibChk).
• SupImp: Calculate a dynamic impact factor by comparison of envelopes from a dynamic and a static calculation.
• Sup2D: Reduce given superposition file results to 2D with values Qz, Mx, and My set to zero. This is intended to be used only for design checks in the vertical plane.
• TrackSup: This action tracks a superposition file and generates the list/excel output of various sources (load case, sup, etc.) making a contribution to each result component in the superposition file.
• SupCoex: This action tracks a superposition file and generates the list of the coexistent in the superposition.
