Roman Dome With Column

Let's use the column from the previous lesson to build a more elaborate structure.

Instructions

1. Continue to the next step.

Instructions

1. Add a cylinder to the workplane.
2. Scale the height to 8mm and diameter to 84mm.
3. Change the color to match the column.

Make a copy of the base to create the main volume of the building.

Instructions

1. With the base selected, choose duplicate from the upper left menu.

2. Scale it's height to 66mm and diameter to 50mm.

3. Use the black arrow to move the copy so it sits on the base.

The main building and it's base need to be concentric, meaning they share the same center. Then the column will be aligned to one axis of the main building. When finished, you should have something similar to the image.

Instructions

1. Select the main building and it's base.
2. Choose the Align tool.
3. Pick the center tabs on both the X and Y axis.
4. Select the main building and the column, and choose the Align Tool
5. Before selecting a tab, left click once on the main building.
6. Select the center tab on the Y axis.
7. Move on to the next step.

Create a duplicate of the column and move it to the opposite side of the dome building.

Instructions

1. Position the camera to clearly see the column and the opposite side where the copy will be.
2. Select the column and choose Duplicate.
3. Hold SHIFT to lock the copy to the axis, and move it to the opposite side.
4. Move on to the next step.

The Duplicate tool can record move, rotate, and/or scale actions done to a duplicate object. As long as the selected objects are not deselected, the duplicate tool will apply the amount to next new duplicate.

Instructions

1. Select both columns.
2. Choose the Duplciate tool.
3. Rotate the copies by 22.5 degrees on either the Y or X axis.
4. Keeping them selected, click the duplicate tool again.
5. You should have 3 pairs of columns as shown in the image.
6. Keep the columns selected and move on to the next step.

Instructions

1. Continue clicking the duplicate button until there is a ring of columns around the dome building.
2. If the columns are deselected, select the two opposite columns. duplicate them, and rotate 22.5 degrees.
3. Move on to the next step.

Make a copy of the base and keep it concentric with the building.

Instructions

1. Select the base.
2. Choose the Duplicate tool.
3. Use SHIFT to lock it on the Z axis.
4. Move the cap so it rests on top of the columns.
5. Move on to the next step.

Make a copy of the main bulding and keep it concentric .

Instructions

1. Select the main building cylinder.
2. Choose the Duplicate tool.
3. Use SHIFT to lock it on the Z axis.
4. Move the second level so it rests on top of the cap.
5. Move on to the next step.

Instructions

1.With the second level cylinder selected, scale it's height to about 25mm.

2. Move on to the next step.

Make a copy of the second level, and scale it while keeping it concentric .

Instructions

1. Select the second level cylinder.
2. Choose the Duplicate tool.
3. Hold SHIFT to scale all axis equally and scale the second cap 4mm larger than the second level.
4. Move on to the next step.

The workplane can be aligned to any object's surface with the Workplane Tool. This will let us set the dome right where it needs to go.

Instructions

1. Press "W" key to switch to Workplane Tool. Notice how the cursor changed.
2. Place the cursor on top of the second level cap. The white arrow should be pointing up.
3. Left click on the top surface. The workplane will turn orange and align to that surface. See the image.
4. Move on to the next step.

Instructions

1. Place a half sphere onto the newly aligned workplane.
2. Move on to the next step.

Scale the dome while keeping it concentric.

Instructions

1. Select the dome.
2. Hold SHIFT to scale all axis equally and scale the dome to have the same diameter as the second level cylinder.
3. Move on to the next step.

Align the dome, having it move towards the main cylinder. Choose a column and remove it. This will become the front entrance of the building.

Instructions

1. Select the dome and the main building cylinder.
2. Choose the align tool and left click the building cylinder so the tabs surround it alone.
3. Click the tabs for X and Y axis only.
4. Select a column where the front door will be, and delete it. When finished with this step, you should have something similar to the image.
5. Move on to the next step.

Now that we have the main shape of the building we can add some details to it. Luckily, we can copy the dome and second level (not including the second cap) which will give us a good start.

Instructions

1. Select the dome and second level cylinder.
2. Choose the Duplicate tool.
3. Move them off to the side as shown in the image.
4. Move on to the next step.

Adjust the size of the cylinder for the new shape.

Instructions

1. Select the cylinder.
2. Position the camera so that you can see the bottom of the cylinder, and the black arrow is pointing down.
3. Use the black arrow to scale the cylinder, stretching it downward, until it is about 80mm in height.
4. Move on to the next step.

Instructions

1. Select both objects and group them together.
2. With the group selected, apply the hole material from the Inspector window.

Duplicate, scale, and move the hole object to add detail to the building.

Instructions

1. Make a copy of the hole object and scale it to fit the second level as seen in the image.
2. Move and/or align the hole object so it is above the opening where you deleted a column. Make sure the hole object is about half way inside the cylinder.
3. Move on to the next step.

Instructions

1. Duplicate the hole object and move it down to the opening.
2. Scale it to fit in between the columns.
3. Make sure about half of the hold object is inside the main building cylinder.
4. Move on to the next step.

The hole object can be duplicated like the columns were earlier in the lesson.

Instructions

1. Design the second level detail with duplicates and variations of the hole shape.
2. Move on to the next step.

Once you are done adding detail, select the hole objects and all of the solid objects they are in.

Instructions

1. Position the camera to view the side of the building.
2. Left click and drag near the objects to create a selection box. All objects inside the selection box will be selected, even the objects behind the building that cannot be seen.
3. Move on to the next step.

Instructions

1. Group the objects together by clicking the group button in the upper right menu.
2. Move on to the next step.

Instructions

1. Select the door hole object and the main building cylinder.
2. Group them together.

You have finished building a dome! Congratulations!
