1 MIN 1 CAD: Get a Fix on CAD Commands Beginning with F, G & H

ZWSchool 2020-01-03 17:27:38
Hi, everyone. Good to find that you’re still hanging in! They always say, fewer but better. Let’s speed up our pace of learning and get a better grip on CAD commands beginning with F, G and H!

HATCH

I feel like we didn’t give enough credit to the humble Hatch command in the article on Super Hatch. With Hatch, you can fill entities with various hatch patterns or gradients to tell what they are made of. First, let’s find out how to specify the patterns, colors and layers of your hatches in the Hatch dialogue box. Steps:
  1. Input [Hatch] and press Enter to invoke the Hatch dialogue box.
  2. Click the icon expand icon at the bottom right of the dialogue box to expand it.
  3. Select a hatch pattern, color and layer.
  4. Select the to-be-hatched entity by clicking it.
  5. Click “OK”.
Now you can easily check and manage your hatches in the Properties panel. Hatch Then, here’s how to specify the angle and scale of your hatches. Steps:
  1. Input [Hatch] and press Enter to invoke the Hatch dialogue box.
  2. Select a hatch pattern.
  3. Customize the angle the hatch pattern is going to rotate, and the scale it is going to scale.
  4. Repeat the above steps 4-6.
See? I can create the standard section of part models in this way. Hatch [su_spoiler title="Tip" open="yes" style="fancy" icon="chevron-circle"]You can view the hatch result vividly while picking the to-be-hatched entities if you tick off the Dynamic Preview option in the Hatch dialogue box. After previewing, press Enter and you can go back to the Hatch Dialogue box. Click “OK” to confirm it.[/su_spoiler]

FIELD

Fields are strings of texts that will be updated along with the change of field values, which means that if objects of the same properties change, the fields will also change accordingly and automatically. They are very helpful with annotation and calculation. For example, let’s see how a total area, in this case, the area of 4 lawns can be automatically calculated by fields. And first, I’ll hatch one of the lawns and calculate the area of that hatch. Steps:
  1. Input [Field] and press Enter to invoke the Field dialogue box after hatching one of the areas.
  2. Choose a field name, select a hatch from the drawing as the object type, choose a property, and click “OK”.
  3. Enter “Height”, press Enter and specify the height of the field.
  4. Insert the field at a proper place.
After I got the area of one lawn in the form of field, I double-clicked the hatch in the drawing to invoke the Hatch dialogue box. Then, I hatched the other 3 lawns. Finally, I used the Regen command to regenerate all the field values and got the total area of the 4 lawns. Field There you go. No more sweating over calculating areas. You mustn’t miss out on this command if you’re a landscape designer.

FILTER

With a filter, you can quickly find the objects you want. Unlike Quick Select that allows you to search for objects of the same features all together, Filter helps you find objects of different features all at once. You can create a filter in 2 ways - Graphic Search and Text Search. Let’s have a look at the Graphic Search first and discuss the Text Search in the Find command section later. Steps:
  1. Input [FI] and press Enter to invoke the Graph filterlocate dialogue box.
  2. In the “Create Filter” section, specify the object type, filter properties and value.
  3. Click the “Add to List” button to add the filtering conditions to the “Filter List” on the left.
  4. Click the “Find” button and the objects matching the conditions will be listed in the “Search result” section.
  5. Select the desired objects in “Search result”, click ”Zoom to” to check whether they are the objects you want in close-up and then “OK” to keep designing.
Filter In this case, I specified the Object Type as Hatch, Property as Layer and Value as 1 so that I easily found the blue gradients in Layer 1.

FIND

Now, let’s talk a bit more about the Text Search module. With the Find command, you can find a specific string of text from the entire drawing, blow it up or replace it. It is really useful when you need to spot a particular string in piles of annotations. Steps:
  1. Input [Find] and press Enter to invoke the Graph filterlocate dialogue box.
  2. Fill in the “Find string” box with the desired texts.
  3. Customize the rest of the find and replace options.
  4. Click “Find” and the strings in line with the texts you’ve entered will be listed in “Search result”.
  5. Select the strings in “Search result”, click ”Zoom to” to check whether they are the texts you want in close-up and then you can choose to replace one of them, replace or select them all.
In the example below, I used Find to locate the annotations, “i=1%” and replace them all with “i=1.2%”. Find

GROUP

As its name suggests, you can use this command to group separate entities. With Group, it is easy to select, move, copy and edit all the components of a group. Steps:
  1. Input [G] and press Enter to invoke the Group dialogue box where you can select, create and modify groups.
  2. Name and describe the new group or check the “Create as unnamed group” box to create an unnamed one.
  3. Click the “Select entities and create group” button, select the to-be-grouped entities in the model space and press Enter to quit selecting.
  4. Select the to-be-modified group from the group list and then make modifications to it as you like, such as removing or adding entities.
  5. Click “OK” to finish grouping.
group With my table and chairs grouped, I can copy them effortlessly. What a useful command for interior designers! [su_spoiler title="Tips" open="yes" style="fancy" icon="chevron-circle"]1. PICKSTYLE is a system variable that controls the selection of associative hatches and groups. The effects of its 4 values are explained below. 0: You can select the individual components of a group or an associative hatch itself. 1 (the default value): You can select an entire group by selecting one of its components. 2: You can select an associative hatch and the object it fills together. 3: Both results of values 1 and 2 can be achieved. 2. Groups are similar to blocks. However, you can select and edit the components of a group separately without exploding it first, which is not the case with a block. And unlike blocks, groups can’t be inserted in other drawings.[/su_spoiler] Got the “g”ist? I hope that you “f”ind these “h”acks useful. If you do, leave a comment to let me know!
