Parametric Modeling

Basic usage: < br / >1. The node editor is where you can design parametric modeling. Parameter modeling consists of nodes and connections between nodes, and nodes are composed of input socket, field and output socket.
2. Add node: click the icon in the toolbar in the node editor window and place the node.
3. Mobile node: when moving a node, drag and drop the node directly; when moving all nodes as a whole, drag and drop with the mouse in the blank space.
4. Zoom node: the mouse wheel can zoom the window size of the node.
5. Connect two nodes: click the output socket of the first node, and then click the input socket of the second node. Only sockets of the same type can be connected. If you are not sure of the socket type, you can cancel the connection by hovering over the blank space.
6. If you enter the wrong data in the node field, the node border turns red.
7. Delete node: right click the node, and then click "delete this node"; right click in the blank space to clear all nodes (caution).
8. You can also find other operations by right clicking in the blank space of the node editor, such as "open scheme file", "freeze parameter entity", "show / hide thumbnail preview", etc.
9. Right click the solid model to extract shapes, points and vectors.
10. When completing parameter modeling, in addition to saving the model, don't forget to right-click "save scheme file" to facilitate importing scheme file to modify the model in the future.

Calculation and selection of nodes: < br / >Calculation < br / >This node type allows you to calculate mathematical formulas. The following elements are accepted in the mathematical formula.
Constant: Pi < br / >Variables: A, B, C, D, e, F, G, h, I, J, K, l < br / >Operators: +, -, *, /,% < br / >Function: min, Max, round, ceil, floor, asinh, asin, sin, acosh, cos, atanh, atan, Tan, exp, log2, log10, sqrt, cbrt < br / >Here are some correct mathematical formulas: < br / >floor(a)
a * max(b, c)
(a + b) / round(c)

Select < br / >This node type is used to select parameter entities that match the query. You can write a selection query using the following elements.
Numerical variables: A, B, C, D, e, F, G, h, I, J, K, l, Nth, width, height, depth < br / >Numeric operators: & lt;, & lt; =, =! =, >=, >
Boolean variables: first, even, odd, last, solid < br / >Boolean operators: and, or < br / >Boolean function: not < br / >Here are some effective selection queries: < br / >not(first)
width > a
first or nth = 4 or last
