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.
After choosing to use the Paint bucket to select the material (Material) that will be added to the workpiece. Many times, it is found that the selected material does not meet the requirements, such as the position or size that needs to be adjusted to the correct proportion.
Sketch Up has a feature to help manage material texture in terms of adjusting the position or size that needs to be adjusted to the correct proportion with the following steps.
To understand the process, I created a backdrop.
Then 1 use the Paint bucket command as shown in FIGURE 2.
2 Choose a material in the group Bricks, Cladding… named Brick Antique 01 as shown in the FIGURE 3 to put it on the surface of the created back drop as shown in the FIGURE 4.
Brick mapping images now appear larger. Compared to people, I want to adjust the size of the brick mapping, which can be done by following the steps below.
Brick mapping images now appear larger. Compared to people Which I want to adjust the size of the brick mapping, which can be done by following the steps in the FIGURE 5.
After selecting a command, Sketch Up will display four symbols (A,B,C,D) for adjusting the detail of the mapping image, as shown in the FIGURE 6.
A: Drag Pin to move texture. Click the pin and drag the mouse to reposition the texture.
B: Drag Pin to Scale/Shear texture Click on the pin and drag the mouse to adjust the scale or shear texture.
C: Drag Pin to distort texture. Click the pin and drag the mouse to distort the texture.
D: Drag Pin to Scale/Rotate texture. Click the pin and drag the mouse to scale or rotate the texture.
This time, I want toresize and rotate the texture to an angle of 45 degrees, so select D, drag the mouse and the texture size is reduced in real time as in the FIGURE 7.
Then twist the mouse to rotate the texture to an angle of 45 degrees as shown. When finished, click the right mouse button and select the done command.
From all steps, we can get the job with the desired texture. By adjusting from the original to make the work more detailed, try this method and try different topics to see how each one works out.
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.
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.
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 telling the size and job details, namely the Annotate:Dimension tool group.
In the Dimension group, there are also separate tools for dimensioning include :
1.Linear– defines dimensions in a straight line (both vertically and horizontally).
2.Aligned– defines 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 the starting point.
To understanding, See the FIGURE 3 showing different dimensions below.
In the next chapter, we’ll look at how to use Dimension.
(Multiple)Point or Point is a command in the Draw group. I think that there are quite a few people who are curious about this command. What is it used for? If you use point to create workpieces, it may not be suitable. Because the work would come out as a line drawn by a point, and no one does that. So what is the benefit of this command?
Point here refers to the reference point itself. Creating a reference point is what we do when we want to divide the workpiece into parts, for example, with one straight line. Want to divide into 3 equal parts.
The dividing point is to use the point as a reference point. Therefore, Point can be used as a reference. Must have a face that is more noticeable than normal spots. We have to change the point style or Point Style to change from the normal way. The command used to change Point Style is ddptype.When typing the command, you will get a window as shown in FIGURE 2.
It found that there are many styles to choose from. Click on the Style box that you want to use.
Now let’s draw a horizontal straight line. Any length, then select the Divide command as shown in FIGURE 4.
Object to divide selects a straight line. Then enter the value number of segments as 4 (meaning divided into 4 parts).
The result is as shown in the FIGURE 6 the line is divided into 4 sections, referenced by points in the selected style.
Therefore, the Point command is the command to create a reference point. Using in conjunction with other commands, Point Style can be set by using the ddptype command.
Continuation of the story AutoCAD 1 Coordinate System Let’s look at the coordinate system (Coordinate) in 3 dimensions. As was known before from The Story of the Axis X, Y, Z are the axes that are already used in 3D work in AutoCAD, so coordinates can be done by referring to these 3 axes as well.
For example, I want to draw a line after a rectangle. (rectangular) to have a length of 300 units diagonally inward on all four sides to create a roof-like shape as in the FIGURE 1. How to do?
The principle is that we will draw a straight line from the starting point to the end point that is in the 3D plane, meaning that we need to know the exact coordinates of this endpoint. We can use the polar coordinate method straight away, according to the structure @dist<xy<xy plane or @ length < angle between the XY axes < angle on the XY plane, therefore If you want to draw a line from any angle, you must first check the UCS Icon if the chosen angle is equal to the plane according to the 2nd right-hand rule or not.
Like the FIGURE 2 below I will draw a line from the starting point (indicated in the figure) that has an angle of -45 degrees to the XY plane and has an angle of 45 degrees upward from the XY plane, thus setting the coordinates of the end point to be @300< -45<45
With this principle, I draw a line from the beginning (indicated in the picture) to the next. which has an angle with the XY plane equal to 45 degrees and an inclination angle up from the XY plane is 45 degrees, so the coordinates of the end point must be defined as @300<45<45 results in long lines. and tilted to the desired angle.
Coordinate setting like this May be a little difficult to understand Trying to learn about angles and the 2nd right hand rule to understand it will help you to understand more.
