These tools form the foundation of many modeling workflows, whether you’re building architectural skins, organic forms, or technical components. ![](https://staticfiles.gleap.io/gattachments/AG6L61N3NOPVjaVrVLQErNKsvUr6ldoAFsnaXtRc70ruLCYnA2o1o77GiNao8o9syNpMcWPA6a8.png) ### **Curve to Surface** Converts a single curve into a surface by extending or filling it, giving a planar or ruled surface based on the curve’s shape. ![](https://staticfiles.gleap.io/gattachments/mq1RybM1QJbvsjPacLxPnHHdsDiWli5xYOsBRyFxxiHABziRDftPaUR5eYXvNfkjVMc25qcjOA8.png) ### **Extrude Point** Creates a surface by pushing a point in a specified direction, forming a ruled surface that stretches from the original point. **Profile**: The input curve that defines the direction and shape of the extrusion. ![](https://staticfiles.gleap.io/gattachments/dk3IKVaWHnJi74UYK2IIS1Oj05hqfbDq3BdF6DRA9Y1fQGX17W51fYoWMckdkG2PIRfudaTLtsg.png) ### **Extrude Curve** Generates a surface by extruding a curve along a direction or path, producing walls, panels, and linear extensions. You can decide the length and direction of extrusion from **Vector** port. _(By default its In Z direction)_ ![](https://staticfiles.gleap.io/gattachments/nW4I1sW7x4MYgZwdzRA1H6ChK56T8U6Trr2uLzfAqwmmW2TSN0k2cM6IXhDvdN5xnkKdqwljCj5.png) ### **Extrude Along** Extends geometry by following a guiding curve, allowing more controlled and organic extrusion paths. **Extrusion**: The geometry or object that will be extended along the path. **Profile**: The guiding curve or path that controls the direction and shape of the extrusion. ![](https://staticfiles.gleap.io/gattachments/Arkl3IJoIUp13CswQqD5JLetfof2D5eiCNxe9Hht2EnJ0F7BcIncNc643zLVfpA6EALmS1fUnrh.png) ### **Sweep2** Creates a surface using two profile curves that are guided along a path or between additional guide curves for more complex shaping. All three curves must lie on different planes for the Geometry to generate ![](https://staticfiles.gleap.io/gattachments/2RefUz9sAB3FKlAHV0hVl99VdvEg6FKIsWmQ4hnANWP0vVrCc1mlUhWfFX5bK93sqmJjBUhoBGO.png) ### **Loft Surface** Creates a smooth surface by connecting several curves in order, blending them together into one continuous shape. The overlapping/common areas of the curves are not included in the final surface. **Degree**: Controls how smooth or curved the loft becomes when connecting the shapes. ![](https://staticfiles.gleap.io/gattachments/MOXe70HUGNWgU1ivZpKAZ9YbQH0KQi8wXth6MCdtbdlioZFDjcE2BffCHplbaMGdIDSqAcpyjx6.png) ### **Revolve Surface** Generates a surface by rotating a curve around an axis, commonly used for circular, radial, or symmetrical forms. **Profile**: The curve that will be rotated to form the surface. **Origin**: The point where the rotation axis starts. **Direction (Input Vector)**: Defines the direction of the axis the profile spins around. **Angle**: How far the profile rotates (e.g., 360° for a full shape). ![](https://staticfiles.gleap.io/gattachments/5fYXYzvyp7JrDJQFaik1PpcXh7lStEbZmVq3WrARlmgbD0xcCoOOoASYG2FNk9F2JfptOIWHZk0.png) ### **Surface from Points** Constructs a surface by interpreting a grid or structured list of points as a UV mesh. ### **Surface from Curves** Creates a boundary-based surface using multiple input curves to define its perimeter. ![](https://staticfiles.gleap.io/gattachments/ip7cXIzb5KAcXkDEdJ20aUKtarKbHnjTBZj4ls5X4qpDEQSXTmNi88edNUTYZIjZusDvioEKRry.png) ### **Pipe** Produces a cylindrical or tubular surface for the input **Radius**, that follows the shape of a path curve. ![](https://staticfiles.gleap.io/gattachments/Mmn3orgIfOXq5Ulm2oGxdETuBbUZZ4jI8pXigOR9YpwSdHJUD7Yg9mGqf7NMQvAME3HlTlKKhin.png) ### **Pipe Variable** Creates a pipe whose radius changes along the curve, allowing tapered, bulged, or organically shaped tubes. **Base Curve**: The path the pipe will follow. **Parameters**: Positions along the curve (0 to 1) where the radius changes. **Radii**: The radius values at those positions, controlling how thick or thin the pipe becomes. ![](https://staticfiles.gleap.io/gattachments/Ubo869XtFwZWDqmPbP6KXHxFhGeoT9XReTh3E1IL0A4cs9eqmdvPJU7CsSioi6SJSXJgj1wdBOf.png) ### **Surface 4Pnt** Generates a surface defined by exactly four corner points, forming a flexible quadrilateral surface. ### **Surface by Edges** Builds a surface by selecting boundary edges, creating a surface that closely matches the surrounding geometry. Does not include the intersectional surface. ### **Sum Surface** Combines two curves into one smooth, continuous surface. The first curve acts like the main path, and the second curve shapes how the surface transitions as it follows that path. ### **Rectangle Surface** Creates a flat, rectangular surface based on width, height, or corner points. ### **Circle Surface** Forms a circular planar surface defined by a radius or boundary circle. ### **Surface Area** Calculates the total area of a given surface. ### **Evaluate Surface** Returns properties such as the point location, normal vector, or curvature at specific UV coordinates on the surface. ### **Surface Edges** Extracts the boundary edges of a surface, separating them into individual curves. **Output Port:** **Edges**: These are the **outer boundary curves** of the surface, the perimeter or outline that forms the visible border of the surface. **Face Edges**: These are the **inner edges** created by trims, holes, or cut-outs on the surface, anything inside the boundary that also forms an edge. ### **Surface Iso Curves** Displays or retrieves the isocurves running along a surface’s U or V directions. ### **Face Normala** Computes the Normal and Center of each surface face, helpful for understanding orientation. ![](https://staticfiles.gleap.io/gattachments/AcLuZDaoQqTNuQV3E5WFaQb6zRUBPnFLgXQC39BSHSTNvypAPshoriJ4iGKLPX2C4fdMs6KlgtK.png) ### **Cap** Closes open surfaces by generating flat or fitting end caps. ![](https://staticfiles.gleap.io/gattachments/5NKM5NQKTUCtBh6iAsHeMrSCHm4PvRBhRXZworUj05KKwm0Tkkh8YTUO4cINK4DO0nxwzEe32k0.png) ### **Offset Surface** Creates a surface that is parallel and at a constant distance from the original one. Hide the Original Geometry Node for better preview.

Arc

Smooth, rounded transition

Parallel curve with arcs

Rounded surface extension

Intersection

Stops/adjusts at intersections

Curve meets other geometry

Surface edges align with other surfaces

Tangent

Preserves tangency, smoothness

Curve follows tangent direction

Surface offset preserves tangency

### **Side Thickness** Adds thickness along the sides of a surface, producing solid-like geometry from sheet-like forms. ![](https://staticfiles.gleap.io/gattachments/LWOJkFnkRqLWtBMHe4QXoFgHf89N36kwNBzVtT9pfZm3NnMte1YwUz4d4j0MGPQd0wLRUBippTh.png) ### **Divide Surface** Splits a surface into smaller panels or a UV grid, preparing it for patterning, tiling, or modular design. You can choose the U count and V count of Grid.
