After Running the analysis under the Results tab defined envelope not showing
Could you please attach the model where several envelopes are shown in that list?
then what is the use of that envelope option , in some model it is shown and in some it is not
Yes and it is not supposed to be shown there.
Only two envelope are there one for strength and one for service and both are not shown there
This dialog is not meant to show all created envelopes. It just allows you to show the enveloped results of the active envelope selected in the Results Setup dialog as I showed in the previous screenshot.
