The following procedures create a web cut that the software can place when a plate and bounded profile are detailed.

Copy and Rename an Existing Web Symbol

  1. Open the file using the Symbol2D environment.

  2. Delete any existing geometry from the file.

Create the Input Geometry

  1. If the bounding object is a profile, copy in the actual profile. If the bounding object is a plate, sketch a spline.

  2. Copy and paste the slot geometry for which the clip will be used.

  3. Delete any unnecessary geometry.

  4. Lock the input geometry segments.

    Bounding Object - Profile

    Use only the necessary geometry.

    Bounding Object - Plate

  5. Create the bounded geometry using only the necessary line segments. Typical lines include Top, Bott, and Top_Range_Right_Bottom.

  6. Lock the input geometry segments.

Name the Input Geometry

  1. Right-click each profile segment, and open the Properties dialog box.

  2. Click the User tab, and check the segment name. Name all the bounded and bounding edges.

Create Input Groups

  1. Create an input group for the bounding geometry.

  2. Create an input group for the bounded geometry.

    A - Bounding Group

    B - Bounded Group

Name the Input Groups

  • Click Name Inputs. Click Name, and select the input name in the Value field. Click Apply.

    A - Bounding

    B - Bounded

Create the Web Cut Geometry

  1. Sketch the web cut geometry on the Default layer or on the CrossSectionPlaneLayer, depending on how it should trim.

  2. Make sure that the geometry forms a closed contour.

Create the Bounding Plate Geometry

  1. If the bounding object is a plate, use a spline.

  2. Use the Place/Offset Curve with Relationship command.

  3. Place the spline on the CrossSectionPlane layer.

Group the Web Cut Geometry

  1. Hold the CTRL key, and select the segments in a clockwise sequence.

  2. Click Group.

  3. Use the Name Geometry dialog box to name the edges that will be welded. If the bounding object is a plate, use IdealizedBoundary. If the bounding object is a profile, the web cut edge name should match.

Constrain and Dimension the Geometry

  • Place the dimensions on the CrossSectionPlane, Default, or NoShortPtAdj layer, depending on your requirements. For more information, see End Cuts.

Place Output Points

  • Place a point to define the location of the flange cut.

    A - Place points for both the top and the bottom flange.

Group and Name the Output Points

  1. Select the points, and group them.

  2. Use the Add Point Names dialog box to name the points.

Add Parameter Names to the Dimensions

  1. Click Symbol Properties, and click the Parameters tab.

  2. The parameter names must match the names in the bulkload file.

Define the Representation

  1. Click Symbol Representation, and assign the geometry to the WebCut group.

  2. Assign the group of points to the WebCutPoints group.

Sketch the Profile Geometry

  1. On the ProfileSketch layer, add the geometry and dimensions that will appear on the profile sketch.

  2. Constrain the geometry to follow the web cut.

  3. Do not constrain the profile sketch geometry to other profile sketchy geometry. Only constrain it to the web cut or input geometry.

  4. Make sure that all dimensions are driven.

  5. Sketch lines away from the web cut, then connect the ends to the web cut lines.

    The profile sketch geometry follows the shape of the web cut.

Dimension the Profile Sketch

  1. Add driven dimensions that need to display on the profile sketch.

  2. Dimensions should be created from the profile sketch geometry.

Place the Profile Sketch Points

  1. TopLengthPoint - This is the longest possible length projection of the top. This point is required.

  2. BottomLengthPoint - This is the longest possible length projection on the bottom. This point is required.

  3. TopConnectPoint - This point is used to connect the web cut on the profile sketch.

  4. BottomConnectPoint - This point is used to connect the web cut on the profile sketch.

  5. RangeConnectPoint - This point lines up the web and flange cut on the profile sketch.

    A - TopLengthPoint

    B - FlangeConnectPoint and TopConnectPoint

    C - BottomLengthPoint and BottomConnectPoint

Create the Profile Sketch Representation

  1. Group all geometry, dimensions, and points that will go on the profile sketch.

  2. Select the group for a representation called WebProfileSketchCurve.

Save the Symbol File

  1. Save the symbol with a .SYM extension.

  2. Before you close the file, check the symbol's timestamp to verify that it was saved. If it was not, click Save As, and overwrite the file.

  3. Save the file to the symbol share under the [SharedContent Folder]\FTLibrary\Web Cuts folder.

Modify the C# Rules

  • Add new Smart Items to the proper selector, then save and recompile the project.

Modify the Bulkload Spreadsheet

  • In the [Product Folder]\ShipCatalogData\BulkLoad\DataFiles\StructDetail folder, modify the FT_SRDConstDetailsEndCuts.xls file to add the new symbol.

Bulkload the Symbol

  • Bulkload in Append or Add mode.

Place the New Web Cut in the Model

  • Flange cuts have an additional input; they require points from the web cut.

  • Flange cuts should avoid cutting the web when the web slopes all the way to the top of the profile.

  • Flange cuts only have two output representations: FlangeCut and FlangeProfileSketchCurve.
