GstarCAD has the ability to add descriptions to the block definitions in the drawing. Issue the BLOCK command, select the block from the list at top, then click in the lower 'Description' section and enter the description and finally click... Read More

Working with block references that represent symbols are essential in some industrial application drawings like electrical schematics, piping, etc. But a headache comes when try to place these blocks accurately overlapping or even breaking other... 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

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

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

Take 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 “Distance Multiplier” property of... 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

For mechanical design, we often need 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 entry frame which is in the right... Read More
