AutoCAD Presspull

Introduction

AutoCAD Presspull is a powerful tool in AutoCAD software that allows programmers to perform solid modeling and editing operations on 2D or 3D objects. It provides a simple and efficient way to modify objects by extruding, offsetting, or tapering the selected geometry. Presspull can be used to create complex 3D models and perform various design modifications.

Features

• Extrusion: AutoCAD Presspull allows programmers to easily extrude 2D or 3D objects by specifying a distance or a reference point. This feature is useful for creating solid objects with depth.
• Offsetting: Presspull can also be used to offset the selected geometry to create parallel copies. It is particularly handy for creating multiple copies of a shape with consistent spacing.
• Tapering: With Presspull, programmers can taper the selected geometry by specifying a tapering angle. This feature is useful for creating objects with a gradual change in width or height.
• Nested Geometry: Presspull supports the extrusion of nested geometry, which means it can extrude objects within objects. This feature allows programmers to create complex 3D models with ease.
• Dynamic Preview: AutoCAD Presspull provides real-time dynamic preview of the changes being made. This allows programmers to visualize the modifications before actually applying them, ensuring accuracy in the design process.

Usage

To use AutoCAD Presspull, programmers can leverage the AutoCAD API to access the Presspull functionality. Below is an example code snippet in AutoLISP, a programming language integrated within AutoCAD, to demonstrate the usage of Presspull:

; Select the geometry to apply Presspull
(setq selection (ssget))

; Specify the distance for extrusion
(setq extrusion-distance 10)

; Apply the Presspull operation
(command "._presspull" selection extrusion-distance "" "")

In the code snippet above, the selected geometry is passed to the Presspull command along with the desired extrusion distance. The Presspull operation is then executed using the "._presspull" command.

Conclusion

AutoCAD Presspull is a powerful tool that empowers programmers to perform solid modeling and editing operations with ease. Its versatile features, such as extrusion, offsetting, and tapering, make it a valuable tool for creating and modifying 2D and 3D objects. By incorporating Presspull into their workflow, programmers can enhance their productivity in AutoCAD.
