A modeling situation may occur which requires a node to be located at a specific position. Some examples of this type of situation are the following.
- A load or constraint will be applied to the model at a specific location.
- Additional elements, such as actuators, beams or pulleys, will be connected to a CAD solid model at a specific location.
- The results must be calculated at a specific location.
These situations will require the addition of seed points to the model. Seed points must be placed on the surface of the CAD solid model. A seed point can be added using two methods.
- If the X, Y and Z coordinates of the seed point location are known, select Draw
Draw Construction Vertex. This will access the Define Construction Vertex. Specify the X, Y and Z coordinates and press the <Enter> key. The seed points will be represented on the model as a small blue square. - Once a mesh has been created, a vertex can be selected. A seed point can be added to a selected vertex by right-clicking and selecting Add Construction Vertices. This method will also allow you to specify a seed point at a location relative to the selected vertex. For example, if you want a vertex to be located 2.5 inches from a corner of a part, you can select the corner node, right-click, select Add Construction Vertices. Then, enter the relative distance from the corner. The model must be meshed again for the vertices to be located at the seed points.
Seed points can be removed from a model by selecting them in the display area, right-click and select the Delete command (or press the <Delete> key).
