CAD how to make dynamic blocks ww

Let's take drawing a bolt as an example. The first thing to do is to draw a basic figure of a bolt.

Create the bolt as a block reference and name it Bolt.

Enter the blocker and start "bolting". Click "Linear" in the "Parameters" column of the "Block Authoring Palette".

Use Linearity to label the start and end points of the extrusion.

Click "Stretch" in the "Actions" column of the "Block Authoring Palette".

At this time, the cursor is in the pick-up box state, click the parameter "Distance 1", and then specify the parameter point to be associated with the action, that is, select one of the endpoints of "Distance 1" as the stretch point.

<> exiting the blocker, you can see that the block reference "bolt" has become a dynamic block, click the arrow, and the bolt can be lengthened or shortened with the mouse.

Dynamic blocks, it is not difficult to understand that the tiles are set with some actions and parameters, so that they move according to our needs. The mystery and difficulty lies in whether the parameters and actions are set reasonably and appropriately, and whether the actions of the blocks meet the requirements. Let's take a look at how to use CAD to create dynamic blocks using doors as an example.

1. After opening the CAD software, select and execute the "Rectangle", "Line" and "Arc" commands in the blank file respectively to draw a 900mm wide flat door.

2. Enter command B, that is, "Create Block", and set the door object drawn in the above figure as a block, and set the name to "Gate".

3. Select "Blocker" in the tool.

4. The software pops up the dialog box of "Block Definition", sets the block of the previous window as an object, brings up the block window, and opens the door tile object in the view at the same time.

5. Set the block parameters, that is, "block writing palette", here we select "linear" and "rotation" to create the parameters respectively.

6. Select "Action", then select "Scale", select the line type that needs to be created, and when the system prompts "Select Object:", select all door objects, and press the spacebar to confirm, thus forming a zoom icon, indicating that dynamic scaling has been created.

7. Similarly, create a new dynamic rotation for the door.

8. Save all the settings just now, and exit the device, so that if you select the dynamic door you just created, you can see some feature point objects.

9. Below, drag the triangular feature point on the left side of the door with the mouse to scale the object at will. At this time, you need to turn off the "orthographic" mode first, of course, you can also select a circular feature point and drag it at will.

CAD is a very important drawing tool, 2D, 3D drawing modeling are supported, so there are many industries in use, it can be said that CAD is a necessary skill for people in the workplace. There are a lot of online CAD learning materials, but most of them are uneven in the two visibility states, and renamed to roughness symbols and juxtaposition, datum symbols!

Step 5: Make the irrelevant pattern invisible in the visible state, hide the datum symbol in the roughness state, and hide the roughness in the datum symbol state.

Step 6: Move the adjustments.

When you finish the visibility state, move the two views so that they overlap, and the overlap point is a commonly used datum point.

Step 7: Test the dynamic block.

Insert the dynamic block into the drawing, select the dynamic block and click the visibility parameter grip, select an item in the pop-up drop-down list, and the dynamic block will automatically change the display state.

b is the current block, and w is the permanent block.
