After a dynamic block is inserted into an AutoCAD drawing, you can select it and modify its display through a special set of custom grips. That’s what AutoCAD calls them. When you select a nondynamic block, you see a single grip at the insertion point. Apr 01, 2019 Draw a circle using Centre and radius command. Enter center as 0,0 and radius as 20. Step 2: Creation of block. Type 'B' and hit enter to create block. Once the command is executed the following window will appear. Enter the name of block. Click on pick point option. Then select the object. Check the 'open in block editor' option and click Ok. Say goodbye to the hours spent editing your library of standard blocks.

In a dynamic block reference, a scale actionbehaves similar to the SCALE command.
The scaleaction is similar to the SCALE command. In a dynamic blockreference, a scale action causes the block's selection set to scalewhen the associated parameter is edited by moving grips or by usingthe Properties palette.
In a dynamicblock definition, you associate a scale action with an entireparameter, not a key point on the parameter. You can associate ascale action with any of the following parameters:
- Linear
- Polar
- XY
Afterassociating a scale action with a parameter, you associate theaction with a selection set of geometry.
Specify theType of Base Point for a Scale Action
The scaleaction has a property called Base Type. Withthis property, you specify whether the base point for the scalefactor is dependent or independent.
If the basetype is dependent, the objects in the selection set scale relativeto the base point of the parameter with which the scale action isassociated. In the following example, a scale action is associatedwith an XY parameter. The scale action base type is dependent. Thebase point of the XY parameter is located at the lower left cornerof the rectangle. When the custom grip is used to scale the block,it scales relative to the lower-left corner of the rectangle.
If the basetype is independent (shown in the Block Editor as an X marker), youspecify a base point independent of the parameter with which thescale action is associated. The objects in the selection set willscale relative to this independent base point you specify. In thefollowing example, a scale action is associated with an XYparameter. The scale action base type is independent. Theindependent base point is located at the center of the circle. Whenthe custom grip is used to scale the block, it scales relative tothe center of the circle.
Specify theScale Type Property for a Scale Action
Using Dynamic Blocks In Autocad Project
When a scaleaction is associated with an XY parameter, the scale action has anoverride property called Scale Type. Thisproperty specifies whether the scale factor applied is theparameter's X distance, Y distance, or X and Y coordinate value distance from the parameter's basepoint.
For example,you specify X Distance as the Scale Type for a scale action in adynamic block definition. In a drawing, when you edit the blockreference by dragging a grip on the XY parameter only along the Yaxis, the associated geometry does not scale.
