Photoshop: Resize images with Image size command

Digital images, whether taken with a camera or download, you can check the image size (Image Size) width x length in pixels size by command Image / Image Size …shortcut key (Alt+Ctrl+I) as shown in FIGURE1.


From the image size (Pixels Dimension) 800 x 446 pixels, compared to the size when printed (Document Size) 28.22 x 15.73 cm. Resolution (Resolution) 72 pixels / inch (the higher the resolution, the larger the file size will be).

If you want to resize the Pixels Dimension, enter the desired number in the width (width) or height (height) box.


Adjusting Image Size to suit use and reduce the file size another way. Because sometimes we don’t need large and high-resolution images, such as images to be sent via email, for example.

AutoCAD: UCS Z Axis

For AutoCAD Tips, now it’s an adjustment technique. UCS (User Coordinate System) when creating work on an inclined plane in a way that aligns with the inclined plane Instead of being perpendicular, for example, there is a piece of solids on one side, as shown in the FIGURE 1. By default, it’s UCS/World.


Therefore, if you want to adjust the UCS to the inclined plane, you must use the UCS/Z Axis command in the UCS tool group as shown in the FIGURE 2.

The UCS/Z Axis command has the following steps:

After selecting the command, AutoCAD will allow us to set the starting point (Origin) to select the Endpoint, the bottom corner of the plane, position 1 as shown in the FIGURE 3.


The UCS Icon will start here. Then let us set the end point of the Z axis (Z Axis point) which is position 2 as shown in the FIGURE 3, then the UCS will come to rest. Parallel to the plane as shown in the FIGURE 3. Try rotating (Orbit) to change the view to the side. You can see the placement of the UCS Icon as in the FIGURE 4.


Create a circle around the midpoint on the long side of the workpiece. It can be seen that the inclined circular cross-section is at right angles to the inclined plane because the Z-axis angle is equal to the inclined side of the workpiece as shown in the FIGURE 5.


Then use the Extrude command to create cylindrical solids along that inclined plane for the next step.


That is, iterating with the Array command to create an orderly array of objects. equal distance per piece makes the work as shown in the FIGURE 7.


Then select the Subtract command to cut the pieces apart. by choosing to keep the larger workpiece according to the steps


Got the work as shown in the FIGURE 9. The detailed solids can then be created further.


In summary, the UCS/Z Axis command helps to make operations based on various planes very easy by just setting only 2 points, namely Origin and Z Axis.

SketchUp: Workshop: Easy way to create a shop front

This weekend There is a fun job for you to practice your skills.

It is a shop front model to present the work. Design related to a shop. This one can be chosen as you like. This example is a fried chicken shop in front of the corridor outside the building.

To start with, we need to create a storefront model first by using Line or Rectangle commands. Really long and tall. For this store, width x=10 meters (10000 mm.), height y=3 meters (3000 mm.), built on all sides, there will be a total of 4 sides.


You will get a wall panel in front of the shop with a white face as in the FIGURE 3. Then select the tool named Materials. If you can’t find it, use Help.


Materials are provided as a set. Divide folders by material type. Select a group folder. Brick, Cladding and Siding (FIGURE 4) to work the next step.


Then enter the choice of materials in this group. Now choose any material. Then go to select Tab: Edit as shown in the FIGURE 5.


Enter Edit mode, there will be a window as shown in FIGURE 6. Then select the Create Materials tool on the right as the arrow points.


Then new materials can be created.


By follow these steps.

1.Name the new crafting material.

2. Go to the Texture section, select Use texture image.

3. Click the folder image. to open, choose a storefront image that has been prepared.

**Shop photos are image files such as jpeg, png. Try to choose photos that have similar proportions to the model. For ease of positioning.

Then put the material into the created model with the Paint Bucket command (see steps for using the Paint Bucket). Result as shown in FIGURE 8.


It was found that the image that was uploaded to the size does not match the model size. Therefore, it is repeated in a table. Can be fixed by going to the option size width x length in the texture by resizing it to be equal to 10000 x 3000, the result is shown in FIGURE 9.


The work has already come out. Let’s practice making storefronts with this technique by yourself again.

SketchUp: Multiple Copy Technique

Many times, when using SketchUp, we want to copy multiple parts or components at once.

Today I have a technique to answer this question for you.


For example, there is one chair, already made into a component, but needs to copy 5 more, a total of 6, follow this step.

1. Select the component you want to copy first, here is the chair as shown in the FIGURE 2.


2. Select the Move tool and press the Ctrl key on the keyboard means copying. When moving the mouse to the right, there will be One more chair as shown above in FIGURE 3.


3 Then type 5* in the square. as shown in FIGURE 4, then press Enter.

There will be 5 more selected chairs as needed. From the example, let’s try to follow with the custom component and enter the amount you want and don’t forget the * sign too.

Sketch Up: Workshop- Planter box

Sketch Up Workshop: Planter box

Cylindrical planter box covered with two marble patterns Placed beside a corridor paved with gray granite. Planting trees along the path to look shady is this week’s workshop.

Step 1: Model the planter box.

Figure 1

Start by using the Circle command (size as you wish) to create a Path first, then use the Line command to create a Face shape as in the example. For the created shape It is a cross section of the plant pot itself. The user can create the shape as needed as shown in Figure 1.

To make it beautiful, use the Arc command (Create an arc) additionally along the corners of the created shape as shown in Figure 2.

Figure 2

Then choose to remove the corner joining lines to create a curved corner, as shown in Figure 3.

The alignment of the created surface (shape) must be positioned 1/4 of the circle that serves the path as it will affect the resulting 3D model. It is advisable to move it to this position.

Figure 3

When the components are complete, go to the Follow Me command (see Instructor), follow the steps below.

Click to select a texture (Face). Click Select Path. Drag the mouse along the path circumference. Until one complete cycle to create a 3D image. As you drag the mouse, notice that the model follows the mouse stroke along the path as shown in Figure 4.

Figure 4

Finish the Follow Me step, get the model of the plant pot as shown in the picture below. The 3D model created may look like it differs from the sample depending on how the created surface looks.

Figure 5

Step 2: Add Realism with Materials

Add material to the model with the command Paint bucket (Instructor : Paint Bucket)

Select the materials available in the Brick and Cladding group.

Choose to put them into the model as you like. The example adds two materials to add interest.

After this we will get a pot of plants. Our style has come as a prototype for 1 piece as shown in Figure 6.

Figure 6

Step 3: Add other elements and arrange the view.

Potted Plants Sketch Up model is available for free download at 3D Warehouse, choose to download directly to your work.

When you get the plant, put it in the pot with the Move command and repeat it for 2 sets.

In addition, for realism in presenting, create a surface with the Line command and add materials to make the floor. footpath and lawn as shown in Figure 7.

Figure 7

After that, use Orbit command (Instructor: Orbit) to adjust the view to get an interesting angle as shown in Figure 8. It’s done.

AutoCAD: Find Point Coordinates with ID Command

To know the coordinates (Co-Ordinate) of a point (Point) on Shape 2D or Form 3D, use the command ID (Command:ID).

The steps for using the command are as follows:

Figure 1

For example, there is a 2D Rectangle shape as shown in the Figure 1.

If you want to know the coordinates of the lower left corner. Type the ID command into the command prompt as shown in the Figure 2.

Figure 2

After Enter to execute the command select the desired point. For accuracy use OSNAP (e.g., Endpoint). When you click to select a point, ACAD will display the X, Y, Z coordinates immediately as shown in Figure 3.

Figure 3

In the case of a 2D shape, the Z coordinate value = 0 because there is no height value.

If it is a 3D form, it will use the same command and ACAD will display the required X, Y, Z coordinates.

Annotate:Dimension – part 1

Because AutoCAD is a vector program (Vector) is mainly used for technical drawing. It is therefore important to tell the size of the workpiece and there is a group of tools specifically for measure the size and entity details, namely the tool group.


In the Dimension group there are also tools that are separated according to the size used. Types include

1 Linear Defines dimensions in a straight line (both vertically and horizontally).

2 Aligned tells dimensions parallel to the workpiece in all planes.

3 Angular tells us the size of the angle in degrees between two objects.

4 Arc Length tells the length of the arc (Arc) from the end of the arc.

5 Radius indicates the radius of a circle. or part of a circle

6 Diameter tells the diameter of a circle. or part of a circle

7 Jogged tells a scaled down version. used in such cases The radial line is very far from the workpiece.

8 Ordinate sizing based on a defined starting point.

For understanding See the figure 3 showing different dimensions below.
