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

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

If you already have a drawing that you consider as a standard, you may want to use the blocks from that drawing. The easiest way to manage the blocks is using tool palette. So do we need to open the drawings, drag and drop each block to the palette?... Read More

Actions 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: Move action causes objects to move a specified distance and angle such as a point,... Read More

Parameters have an appearance similar to dimensions. Parameters also specify positions, distances, and angles for geometry in block reference. When you add a parameter to a dynamic block definition, the parameter defines one or more custom properties... Read More

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

General Steps of Creating a Dynamic Block Definition In order to get a Dynamic Block Definition, improve block editing efficiency and avoid repeating modifications, we can create Dynamic Block by the following steps.  Step1: Planning: Before... Read More

You can use this function to multi-select objects with the same name in specified area. Menu : Express>Selection Tools>Get Selection by Block Name Command Entry : GETBLKSEL Operation steps: 1.Start the command. 2.Select object, specify a block... Read More
