With our last article, I hope that you’ve got to know how to use CAD commands that begin with A.
Now let’s move on to B!
As its name suggests, this command is to create blocks.
A block is an entity composed of several independent entities, making it easy for you to create and use different combinations of objects.
- Draw the geometrical entities to be included in the block.
- Select all the entities to be included in the block.
- Input [BLOCK] and press Enter.
- Name the block.
- Define the base point, which is the insertion point of the block.
- Define the behavior (usually, you can go with the default “Allow exploding” option).
After creating a block and saving the drawing, you can open it in the Design Center or add it to the Tool Palettes for later access and use.
After inputting this command, the Block Attribute Manager will pop up and allow you to manage and edit the attributes, texts, and properties of attribute blocks.
Keep reading to see how BEDIT can help you with this issue!
Sometimes you may want to modify the blocks you have already created. The BEDIT command helps you edit them easily in the Block Editor.
- Enter [BEDIT] and press Enter.
- The Edit Block Definition dialog box will appear.
- Select one definition name of a block from the list.
Then you can edit the selected block in the Block Editor. For example, defining its attributes to avoid the issue we’ve mentioned using BATTMAN.
If you want to print some object(s) in your drawing, try using BMPOUT to save them in the Bitmap (BMP) format for a better result since this file format stores the color data of each pixel in the image without any compression.
- Input [BMPOUT] and press Enter.
- Select the object(s) to be saved in .bmp format.
- Input a file name.
- Specify the save path and click Save.
Then you can create a BMP file containing the selected object(s), which are of higher resolution than JPG files.
This command is a must for drawing U-shaped staircases in a plan! It is useful for drawing circuit diagrams as well.
For a quicker breakpoint selection, I suggest that you modify some settings first. Right-click on the Object Snap in the status bar at the bottom and select Settings to open the Drafting Settings dialogue box. On the Object Snap menu, select all options but the Object Snap On as the image below shows.
- Input [BREAK] and press Enter.
- Click on the entity that is to be broken (wherever you click is the first breakpoint by default).
- If needed, input “first” or simply, “f”, press Enter, and click on the first breakpoint on the selected entity.
- Specify the second breakpoint on the selected entity with a click.
Then the part between these two breakpoints will be cut off.
That’s all for this time! “B” sure to practice and review regularly, and “C” you next time!
