10A. DIMENSIONING PART 1/4

3. Existing construction and addition of new construction The procedure followed here is a "mixture" of the first two previously mentioned. You define the two materials (New and Existing) and then do selective sizing in two phases: - You define the Existing as the active sizing material and selectively size only the Existing elements and then - You define New as the active dimensioning material and dimension the New. OBSERVATION: If you want to change the category of an item from New to Existing, you simply dimension it selectively with the corresponding material active. Finally, by selecting the "Apply to all categories of items" button, the materials you specify for one category of building elements (e.g. Pillars) are automatically copied to all other categories of building elements and so you do not need to specify them again, provided of course that the qualities are the same. This feature applies to both new and existing hardware.
