Edit mass families

00:04

Being able to edit the individual faces, edges and points that make up a form

00:09

allows us to easily create more complex shapes.

00:13

Currently, if I move my mouse to the center of a face here,

00:16

we can see that there's no preselection highlight

00:19

and in order to select any objects, I need to click on the edge of them.

00:24

So looking at the status bar at the bottom here, on the right hand side,

00:28

I'll enable the select element by face option,

00:32

which means we can now move to the center of an object here

00:35

and click to select it rather than having to pick one of its edges.

00:41

Once selected,

00:42

we have the 3D drag controls available to us to manipulate that face.

00:47

I'm going over the blue arrow head here

00:49

and dragging

00:50

it will constrain it vertically so we can move this up and down but not to the side.

00:57

And we can also edit the temporary dimensions here to make it more accurate.

01:02

So I'll set this one to be 50 ft.

01:05

The green and red arrowheads will constrain the face to the horizontal X and Y axis.

01:12

And we've also got the planar constraints here in the corner,

01:15

which means we can move it in both X and Y.

01:17

At the same time,

01:22

I'll go to the quick access toolbar and just undo this last edit.

01:27

And we can use these same controls now on edges and the vertex points too. So

01:32

I'll select the back edge of the form here.

01:35

And we can see we have those 3D controls again

01:38

and I'll use the blue Z axis constraint here to drag this vertically up.

01:42

And we can see that that's applied a slope to that top face here.

01:47

We can also edit temporary dimensions to be more accurate.

01:51

And equally, we can snap to other objects. So

01:53

I'll drag this one back down

01:55

and we can snap to the edge of the connected solid form here.

01:59

So we then have that top face sloping backwards to meet it.

02:05

We can also use these controls to manipulate points.

02:07

So on the corner here, we'll select the point

02:10

and this now will control the three faces that connect that, that corner.

02:15

We'll use the green arrow head here and we'll drag this in

02:18

and we'll use the alignment tools here to align to the existing edge in the model.

02:23

We can come to the other side and repeat this. So we'll select this point

02:27

and drag it in so that we have the alignment aligning with the face behind this.

02:33

And we can see now that we've got quite a complex form on the end here

02:37

with it sloping and the edges tapering in at the top,

02:40

resulting in some complex curved faces.

02:45

We can also use some of the standard modified tools such as move, rotate and scale.

02:52

So if I select on the inset face at the end of the model here

02:55

and then from the modify form ribbon on the modify panel,

02:59

we'll click on the scale tool.

03:02

And then for the origin point,

03:04

we'll click on the end of the reference plane here which is in the middle of this face.

03:08

And then we'll click to the right hand side

03:11

and then we can drag this back in to make it smaller. And

03:14

I'll type 25 ft in a dimension here to set that an accurate size.

03:19

And we can see now that that face is scowled in

03:22

and the connected faces have all tapered and stretched to take up the new form.

03:28

Next, we'll look at the X ray mode for editing forms and

03:32

looking at the canopy that's been swept around the edge of the opening here.

03:35

We'd like to manipulate this shape.

03:38

So I'll select any part of it, just one of the edges here

03:41

and then go into the modify form ribbon

03:43

on the form element panel.

03:45

You can see we have the X ray mode and I'll click to enable this.

03:50

And we can see then that the solid form is now transparent

03:53

and looking a little closer.

03:55

We can see the profile and the edges and points that make up that profile here.

04:00

And I can select one of those points now

04:03

and

04:03

this time we'll edit the temporary dimension. So we'll change this to be 1 ft

04:08

and we can see that that's moved that point in

04:10

and has tapered the edge of the canopy here.

04:13

And even though it's transparent,

04:14

we can see that that's been applied around the entire canopy.

04:19

Now with it reelected, we'll go up to the modify form ribbon again.

04:23

And from the form element panel,

04:25

we can see that we've got the option to add an edge.

04:28

So I'll click on this.

04:29

And now as I go over this end face here, we can see the preview of an edge being added in.

04:34

So

04:35

I'll click to place this in

04:39

and we can see now that it's prompting us to place more ages. So

04:42

I'll click, modify to finish this.

04:44

And we can see now that we've got an extra point in the profile here

04:49

and I can now select this point and

04:51

using the drag controls here, we can drag this out

04:54

to manipulate the shape of that profile. So

04:57

once we've got it into the location, we need,

04:60

we can see that reflected through it all.

05:05

Now with it selected,

05:07

we'll go up to the modify form ribbon

05:09

and will disable the x-ray mode.

05:12

And we can see that now back in its full solid form,

05:20

looking at the main block,

05:22

we can edit the two D profile that makes up the end of this.

05:26

So I'll select part of the form

05:29

and then from the modify form ribbon

05:31

in the mode panel, we see that we can have the edit profile mode.

05:35

So I'll click to enable this.

05:38

Now, I need to click the end of the profile that I want to edit.

05:41

So we'll click on the end here.

05:43

And now we can see we have the sketch lines of that profile

05:46

and looking up at the modify edit profile ribbon.

05:49

We've got the sketching tools here. So

05:51

I'll enable the line tool

05:54

and now zooming in a little,

05:57

we'll start to

05:58

draw away from the corner here and I'll type in the 11

06:01

ft for the dimension to set the end of this line.

06:04

And now coming down at 100 and 35 degrees,

06:07

we'll snap to the intersection of the vertical line

06:10

to create a sham ford corner.

06:13

So I haven't got that line created. I'll click modify to finish

06:17

and now I'll select the line

06:19

and from the modify panel here,

06:21

I'll click on the mirror, pick access tool

06:24

and then select the vertical reference plane here

06:27

to mirror this to the other side of the profile.

06:30

So now we just need to tidy up the corners to create an enclosed shape.

06:34

So from the modify ribbon on the modify panel,

06:37

we'll click the trim extend to corner tool

06:40

and now we just need to click on the bits of the line that we need to keep

06:45

to create an enclosed profile as we want it.

06:49

So I haven't got that shape. We'll go up to the ribbon here and click finish edit mode

06:53

to finish editing that profile

06:55

and straight away,

06:56

we can see that new profile incorporated into the end here

06:59

giving us the tapered faces going up to the middle.

07:03

So we'll repeat this at the other end of the form. So

07:06

with an edge selected,

07:07

we'll go back to the modify form ribbon and click edit profile.

07:11

And again, we just need to click this in to confirm that's the profile.

07:16

And this time, I'll choose the pick lines tool

07:19

and now I can pick on the Shatford edges

07:22

on the end that we've already done

07:24

and these will be projected into the profile.

07:27

So I haven't got those. We now just need to use our trim extender corner tool once more

07:31

to come and tidy up the corners and make that in closed shape.

07:38

And then we click finish edit mode

07:41

to finish editing the profile.

07:42

And again, we can see that same profile added to the opposite end.

07:47

And we've now got these shamed

07:48

edges across the corner here.

07:52

Finally looking at the roof here, we want to lower down the front edge.

07:57

So I'll select the point at the top of the roof here.

08:00

We can see that we've got the 3D drag controls, but

08:03

they're currently set to be in local orientation

08:07

and this is shown by the arrowhead B in orange.

08:10

So I'll press the space bar on the keyboard

08:12

and that will swap them to global orientation.

08:15

And now I'll just use the blue arrowhead here to drag

08:18

this vertically down to the mid point of this edge.

08:21

And then once we've released that,

08:23

we can see we've now got that slope coming across the front of the roof here.

08:27

And that gives us quite a complex profile

08:29

and also finishes the editing that we need to make to our mass.
