Edit a model in 3D Sketch

00:04

We will review how to edit an imported building file in 3DSketch, add floors, and generate area metrics.

00:14

If you would like to make an edit to your imported OBJ, you can do so in 3D Sketch.

00:29

To edit this imported OBJ building in 3D Sketch,

00:35

select the building in the canvas and choose "Edit in 3D Sketch".

00:45

A pop up will ask you if you would like to convert this object.

00:49

Click "Convert object" to continue.

00:55

You have now entered the 3D Sketch sub mode.

00:59

We are going to edit our building to make it taller and to curve the front edges of the building.

01:06

Let's first select the front face.

01:12

A series of tools will become visible on the toolbar to the right.

01:16

Let's click the "Flatten faces" button.

01:23

Now select the roof face of the building.

01:27

Locate the "Extrude" button on the toolbar and select it.

01:34

Now find the face centroid on the roof face and select.

01:41

You can either drag the face upward along the Z axis or enter the desired height.

01:48

Let's put 75 ft.

01:52

And click "Enter".

01:54

Click "Escape" to exit the extrude tool.

01:60

Now we'll curb the sides of our building.

02:07

Select the arc by three points sketching tool.

02:15

Click to start drawing the arc from the edge midpoint,

02:21

and click the opposite edge mid-point and expand the arc.

02:31

Let's repeat that on the other edge.

02:48

Now select one of the new curved triangle faces you created,

02:55

find the "Extrude" button and extrude down towards the ground.

03:04

Extruding down will delete the geometry, leaving us with the curved building edges.

03:18

Click "Escape" to exit the tool.

03:21

Lastly, let's slope the roof of our building.

03:25

Select the rear edge of the building.

03:36

Locate the move tool in the toolbar and go back to select the edge mid-point.

03:45

You can either drag up the Z axis or you can enter a specified length on your toolbar.

03:53

Let's enter 20 ft.

03:57

And click "Escape".

04:05

Now that we have edited our imported OBJ building, let's add floors.

04:13

Currently, our building is identified in Forma as a generic object.

04:19

In order to get area metrics like GFA RA and building coverage, you must add floors.

04:27

Ensure that your entire building is selected.

04:33

You should see an option to add floors on the right-hand side.

04:37

Go ahead and click "Add floors".

04:41

Four stacks will automatically be generated for the building and the canvas, and now you can see area metrics.

04:49

We can also adjust the height of the floors, on the right and see the changes reflected in the canvas.

05:06

Once the building looks good, click the check mark at the top of the screen to finish your 3D Sketch session,

05:14

and to save your work.
