CHAPTER 2 "MODELLING" 57 4.2.1.4 Consolidation of grids in cases where a 2nd dwg is imported in masonry studies In cases where in masonry studies a 2nd dwg is imported, the surfaces are not included in the 1st group and a second independent group is created. The procedure to follow when you have two or more floor contours from different dwg is as follows: - Import the first dwg, - you do, as you know, a face recognition and create the ground floor. - Then you bring in the second dwg, - you identify faces and "glue" the first floor on top of the ground floor. You now have two main groups and lines that are identified and/or need to be broken. Same process for as many floors as I have. Finally, using the "Consolidate" command, you select all the main groups that have been created and create a new one that includes all the subgroups with their outlines now as they should be. If you want, you can now erase the original groups and their outline lines. 4.2.2 Outer Limit with Lines-Bow Instruction to set the Outer Limit of the surface. OBSERVATION: If there is no grid, the dialog box for defining the grid as previously described opens. If there is a defined grid, it is used as described below. To define the outer boundary of the surface grid, you first draw it with the help of lines, polylines or arcs. Then select the command and: - If the outline is closed and there are no common lines with other outlines and/or branches, then it is sufficient to left-click on one of the lines to set it and right-click to complete the command. - If the contour is closed and there are common lines with other contours and/or branches, then left-click and point to the lines of the surface contour one by one. - The program provides automatic error detection in finding closed contours for the definition of surface contours and displays in red X the points where the selected contour is not closed.
