35. Now you can see all the legs, in red font.

36. Do the same for the string “table.” This highlights

hidden tables, table tops, and the coffee table.

Cutting Openings

Components can cut an opening on one face only, so if

you are working with double-faced (or double-sided)

walls, the back face will not be cut.

To create openings on both faces, you need a few extra

steps.

Cutting Method 1

1. Create an arched cutout on a thin box.

2. Select the window objects, and create a component.

Because this component contains more than one

cutting face, it cannot align automatically to a face -

the component would not know which face to align

to or cut. Therefore, None is selected for Glue to,

and Cut Opening is grayed out as well.

3. Insert another one of these from In Model; the wall

is not cut.

4. To resolve this, explode the component. The lines of

the window are thick, so fix this by redrawing any of

the window lines or segments.

5. Now you can erase the window face. The cut is not

made on the back face, however.

6. On the back face, do the same thing - redraw one of

the window segments and erase the window face.

TIP: Another way to create the cutout would be to explode the

window component, redraw a segment of the window on the

front face, and Push/Pull to the back face.

Cutting Method 2

1. Starting with a box and a window like before.

2. Because components can only cut through one face,

we can eliminate one of the cut faces. Erase the back

face of the wall.

3. Now when you make a component out of the window

objects, Cut Opening is available (and checked),

and the component will glue to Any face.

4. Create the component, and drag this component to

create another window on the front face. This time,

the window cuts the front face. The back face of the

wall, however, is still missing.

5. Recreate the back face. Explode both of the windows

and resolve the thick lines.

6. Erase the window cutouts on the back face.

Creating a Window Component

Plus a Cutout Component

Here’s a convenient way to handle cutouts for

components that have a non-rectangular shape. Basically

you create two components to be used each time you

insert the cutout - one is the component itself and the other

is used as the cutout.

1. Make a vertical wall and create an arch outline plus

offset. Copy these arches to the other side of the wall,

and Push/Pull them out the same distance.

2. Create a post in the center of the window, and use

Push/Pull to cut the window on either side of it.

3. Push each of the four walls of the post slightly

inward. This ensures that the post is contained within

the wall, so that you won’t see this post when you

first insert the window. Erase any unneeded lines. (If

you’re ambitious, you can resolve the extra material

at the top of the post.)

4. Select the entire window and make it a component

called Arch Window Frame. Glue it to None.

Because we want to set the location of the insertion

point, click Set gluing plane and set it like this:

5. Click Create to create the window component. Now

insert another copy of the component. It is inserted at

the correct depth, but there is no cutout. You cannot

see the post, and the wall face hasn’t been divided by

the window.
