Size constraints
When undertaking an Autodesign, the Size Constraints property allows you to ensure that the sections proposed by Tekla Structural Designer match any particular size constraints you may have.
For instance:
- Minimum width - you may want to ensure a minimum flange width to satisfy bearing requirements for any supported beams. To achieve this, you would enter a value as the Minimum width, and Tekla Structural Designer would not consider sections with flanges less than the specified minimum width for the design of the beam.
- Maximum depth - you may want to ensure that the maximum beam depth is specified to ensure that it fits within a floor zone. To achieve this, you would enter a value as the Maximum depth and Tekla Structural Designer would not consider sections with depths greater than the specified value for the design of the beam.
- Max span/depth ratio (beams only) - you may want to set a max span/depth
ratio limit above which autodesign will reject sections that are of
insufficient depth.
- The depth is taken as the depth from the section properties - for single and double angles this is the vertical leg length.
- Limit is not applied to any member which has rotation.
Note: Size constraints only work when undertaking
an Autodesign

You can control which sections in a design order list are considered, by following the procedure below.
