[0048] Step S13, defining marking information for marking to a marking special node of the ship model to complete the marking work.

[0049] It should be noted that the ship model to be labeled has model information and component information, so first the labeling target is identified and obtained, then labeled according to the preset three-dimensional labeling symbol library, and after labeling, the labeling information used for labeling is defined to the attributes of the ship model, so that when the user operates the mouse to hover over the ship model or the component on the screen interface, the labeling information will be displayed.

[0050] Further, the model information to be labeled in the ship model is identified, and the ship model is labeled based on the pre-constructed three-dimensional labeling symbol library, specifically including:

[0051] Match the three-dimensional labeling symbol library based on the standard drawing to generate a component labeling configuration table;

[0052] Identify the model geometry features and process information to be labeled to call the labeling configuration table to label the corresponding symbols, wherein,

[0053] Identify the model plate thickness orientation information to be labeled to call the labeling configuration table to label the plate thickness orientation symbol;

If there are, the positioning size between the main plate end and the nearest component is labeled, and the continuous positioning size between the component and the remaining components is labeled in sequence, and the plate thickness orientation label is labeled at the positioning size line. If the to-be-labeled component is at an integral position, a rib position label is additionally added.

If there are, the components on the main plate thickness surface are labeled according to the S21 step. The component features under the group erection are traversed to check whether the component boundary is flush with the main plate boundary. If not, the positioning size between the unflush boundary of the component and the nearest boundary of the main plate is labeled. The component features under the group erection are traversed to check whether the component installation angle is perpendicular to the main plate. If not, the acute angle formed with the main plate is selected to label the installation angle size.
