1. API Connection
To use MIDAS GH, you must first establish a connection with CIVIL NX.
1-1 Execute the Grasshopper API Connection Component
1. In Grasshopper, navigate to:
① [Midas] > ② [Tools] > ③ "Midas Setting" component, and execute it.
2. Double-click the ④ icon in the "Midas Setting" component to open the "Midas Setting" window.
1-2 CIVIL NX API Setting
1. In CIVIL NX, navigate to:
ⓐ [Apps] tab > ⓑ [API] group > ⓒ Midas Settings, and execute it.
1-3 API Connection
1. In CIVIL NX, click the "Copy" button for ⓐ Base URL.
2. Paste the copied value into ① Base URL in Grasshopper.
3. In CIVIL NX, click the "Copy" button for ⓐ MAPI-Key.
4. Paste the copied value into ① MAPI-Key in Grasshopper.
5. In CIVIL NX, click the ⓒ "Connect" button.
6. In Grasshopper, click the ③ "OK" button.
Once connected, the Midas Setting in Grasshopper retains the settings information. It only needs to be updated if the MAPI-Key changes.
2. Component Execution
Once the connection is complete, let's verify the connection by creating an element in CIVIL NX.
MIDAS GH, like CIVIL NX, supports one-dimensional elements such as "Beam", two-dimensional elements such as "Plate", and three-dimensional elements such as "Solid". Among these, we will start by creating the simplest element, the "Beam".
2-1 Create Component
1. In Grasshopper, navigate to:
① [Midas] > ② [Node/Element] > ③ "Beam", and execute the component.
2-2 Input Data
1. Create a ① "Line" component in Grasshopper.
2. Right-click on the icon of the "Line" component and select ② "Set One Line".
3. In Rhino, specify the ③ "Start Point" and ④ "End Point" to create the line.
4. Connect the ① "Line" component to the ⑤ "Line" input slot of the "Beam" component.
2-3 Run Component
1. Execute the ① "Run" button on the "Beam" component.
2. Verify that ② "Node" and ③ "Element" are created in CIVIL NX.
The component functions even with the minimum required input values. However, data must be provided for the API to function if there are no default values specified in the manual.
