Dynamic blocks are used frequently in daily work, but many people use dynamic block galleries that are collected from the Internet, and these tiles may be a little inconvenient in the process of use, so you need to make them manually.
Next, I will take you to systematically understand from the following three aspects, what is a dynamic block, and what convenience and help can be provided for our mapping work?
1. How to understand dynamic block, and what are its classifications and advantages?
2. How to make a dynamic block?
3. How to use the distance multiplier and increment settings in dynamic blocks?
01. What is a dynamic block?
How do you understand dynamic blocking, and what are its classifications and advantages?
The production of dynamic blocks has always troubled many people, so let's take a look at the production skills of dynamic blocks.
1. How to understand dynamic blocks?
Let's start with its definition:
a. Definitions:
The key to the definition of dynamic blocks is to set the parameters and actions reasonably, so that the tiles can change according to our needs.
b. Uses:
You can use dynamic blocks to create blocks that can change shape, size, or configuration, and you can integrate functions such as stretching, rotating, mirroring, scaling, and so on.
c. Tile classification:
(1) Normal tiles: select object group tiles;
(2) External Tiles: Output tiles as blocks;
(3) Dynamic block: customize the parameters according to the needs, and the tiles will change accordingly;
(4) Enhanced attribute block: attach some data to the label on the block;
(5) Nameless block: You can't edit it in place, you can only explode the edit;
(6) Nested blocks: the tiles contain other tile contents;
2. What are the types of dynamic blocks and their advantages?
Classification of dynamic blocks:
a. Move
b. Scaling
c. Stretching
d. Polar shaft stretching
e. Rotation
f. Flip (mirror)
g. Array
h. Inquiry
......
In addition to these commonly used action commands, there are many parameter sets and constraints that can be used directly with dynamic operations to achieve the same purpose.
Benefits of using dynamic blocks:
a. Assign block parameters to facilitate the use of block stretching
b. Reduce&Simplify the drawing operation steps
c. Improve the efficiency of drawing
02. How do I make a dynamic block?
After understanding the concept and classification of dynamic blocks, let's take a look at how dynamic blocks should be "done".
Let's analyze its usage tips from the following 3 aspects:
1. How to make a stretch dynamic block?
Extrude Dynamic Block Steps:
a. Select the door sleeve, B command into a block, enter the name of the block, and determine the position of the base point of the block;
b. Double-click the block to enter the block editor
c. Click on the line type in the parameter column to add the line type parameter to the door sleeve;
d. Select the distance 1 parameter, formulate the stretch control point, and separate the stretch control point from the block control point as much as possible;
e. Formulate the extruded frame according to the requirements of the command bar, then select the object, and the space is confirmed;
f. Formulate the extruded frame according to the requirements of the command bar, then select the object, and the space is confirmed;
2. How to make a zoom dynamic block?
Extrude dynamic block operation steps:
a. Create a block and pay attention to the position of the base point of the frame;
b. Create a block and pay attention to the position of the base point of the frame;
c. Select Linear in the parameter bar and add linear parameters to the rectangle;
d. Select zoom in the action bar, add zoom action to the linear parameters, and select all objects including parameters, and the space is determined;
e. Close the block editor, and check whether the tile is scaled incorrectly, if it is correct, the scaling dynamic block is completed;
3. How to use the polar axis dynamic block?
The creation of polar stretch dynamic blocks is basically the same as that of stretch dynamic blocks.
The parameter created is the polar axis, and the action is stretched as the polar axis.
The difference between them is that the polar axis stretches and when selecting the object, two X and Y axes are chosen.
After the block is edited, you can control the edit point to rotate and stretch the object at the same time, which is equivalent to a set of two dynamic commands, Stretch and Rotate the object.
03. How do I set up dynamic blocks?
The main thing is to use the distance multiplier with the increment setting in the dynamic block:
1. How to use the distance multiplier in dynamic blocks?
When it comes to the distance multiplier, it is estimated that many friends are even more confused, what is the distance multiplier?
For example, everyone will understand instantly~~
Above
When we encounter double doors, because the width of the door leaf in a project may be inconsistent, so we must constantly adjust the width of the door leaf, but the door style is the same, is this operation more troublesome?
Someone said that it is not enough to use stretching directly, do two stretches, and then adjust both sides.
Of course, this method is possible, but it is nothing more than a bit more troublesome, so we use the distance multiplier to simplify the operation steps and complete the stretching action more efficiently.
a. The base point of the block is set at the lower left corner of the door sleeve, which is separated from the tensile base point;
b. Select the linear parameter and set it below or above the door;
c. Select the stretching action to give linear parameters, select one side of the door leaf as the stretching range, and the space is determined, and then you can test whether the stretching is successful;
d. Select the stretching action to give the same linear parameter, select the door center line for the stretching range, including the door handle and the door opening line, and then cancel the selection of the door frame range, otherwise the stretching action will be wrong, and the space will be determined;
e. Select the second stretch action icon, Ctrl+1 to bring up the property panel, select the distance multiplier in the substitution column, set the value to 0.5, and then test whether the dynamic block is successful;
2. How do I use incremental settings in dynamic blocks?
The setting of the increment is to set the stretching distance on the basis of the stretching action, and the distance indication is displayed when stretching, which is generally set to the commonly used size;
We continue to set increments for this double door;
a. Double-click the door block to enter the block editor and select the linear parameter;
b. Ctrl+1 brings up the property panel, and in the value set column of the property panel, select the increment in the distance type;
c. Set the distance increment value of the double door to 50, the minimum distance is 1200, and the maximum distance is 1600, and the distance reference point will be displayed at the stretching action;
d. Test the tensile block, each stretching distance is fixed 50, the minimum distance of the door width is 1200, and the maximum is 1600;
The list function in the value set is to directly set the fixed door width, and then switch between the set values when stretched;
Select the small button to the right of the distance list;
Enter the door width value to be added in the panel, click Add, click OK, and the width indication of the corresponding value will appear next to the stretching action;
Brief summary.
Okay, that's all for today's sharing, and finally we summarize the key points of today's knowledge through a map:
