You use the Block Editor to define and modify the objects and behavior in a block definition. In the Block Editor, you add parameters and actions, which define custom properties and dynamic behavior.You can access the Block Editor by typing BEDIT... Read More

For mechanical design, we often need to stretch the keyway to a certain length. Now, let us see how to realize the accurate stretch.1. Pick Linear Parameter: In block editor, pick the linear parameter, then click the entry frame which is on the right... Read More

Dynamic Block Creation (Linear Stretch) For example, during mechanical design, we often need to change the position as well as the dimension of the keyway. In this section, we will add a Linear stretch function for the keyway on the step shaft.1. Add... Read More

Open Block Editor (BEDIT), choose the Angle offset from 0°to 30°in the action property, save and exit the block editor Select the Dynamic Block and then move the right side grip. You will find it can only move in the direction of 30°as it is... Read More

Block actions (BACTIONTOOL) define how the geometry of a dynamic block reference will move or change when the custom properties of the block reference are manipulated in a drawing. Move Actions Command Entry : BActionTool → M In a dynamic block... Read More

If you want to realize symmetric stretch keeping keyway center no change and the length of smaller diameter shaft changes with stretch at the same time, how will realize that?1. Add Stretch for Step Shaft: Add stretch parameter and action for step... Read More

Take the step shaft as an example, if we stretch the left part of the step shaft and the keyway still is at the center point of smaller diameter shaft after stretching. As the following picture shows:   Then, we use the “Distance Multiplier”... Read More

There is an easy way to realize the two-way stretch which is adding two stretch actions. Though it can realize a two-way stretch, the action of stretch is independent. The parameter needs some additional setup to realize the two-way symmetrical... Read More

When you use the "roughness symbol block" to label the spare parts, the symbol is sometimes already in the right position, however, the characters' direction is not right. We need to add the "character flip" function to receive the correct label... Read More

Using the Visibility Parameter function, you can control the display and hide a certain view in Dynamic Block. 1. Prepare view: Draw three cars as below and define all of them as block.    2. Add Parameter of Visibility: Enter into Block... Read More
