The element property Section Count refers to the number of spatial sections into which the element is divided along its length by the implicit numerical engine. For any element there will be a minimum of five sections. Depending on the value of the Computational Distance property, which you set in the Property Editor for Calculation Options, additional sections are added for longer pipes. The default computational distance is 50 feet so that there will be five sections for any element up to 250 ft. Beyond that length, a section is added for each 50 ft of length. You can control the number of sections by increasing or decreasing the computational distance, which will decrease or increase the number of sections accordingly.
