Section tool? I have to check that out. Offset or section... I use the
offset a lot...
Funny I was making a hole in a ply plate, and used the offset to draw it.
then pushed it back down through the ply... from the top it looked all
the way through. From the bottom no...
over and over I struggled. Finally highlighted the hole, and hit
delete... BINGO.. not everything works as expected, but there seems to
be a way. Not always so intuitive... especially zooming... I find I
have to go to the other side of the view to zoom out to re-center, so I
can get to the piece I want to see. If I just put my mouse over the area
I want to bring in, I still can't see the rest of that.. so goto the
other side, zoom out, then mouse to the center of what I want to see and
zoom in... I know I can do shift middle and drag, but that is a pain
sometimes, too many operations.
Section tool. IIRC it is a group of tools that you might have to select
to show up from the View/Toolbars window.
You select the section tool and click it on a surface, it will
immediately show a larger see through but bordered window on the surface
that you clicked. Next select the border of that section window and
move it toward the object. For small movements you will probably have
to zoom in. If you do this right it will make the object/component
appear to have been run through the planer several times to expose the
insides of the pieces.
Extremely easy to use once you understand the concept. When I took
drafting in school many many years ago we had to draw the section plane
and draw what we imagined to be the look inside the part had we sliced
away a section.
Just stick with it. It will get easier and easier. I am continuously
finding faster and easier ways to do things. Just like the section
plane i mentioned above. That just came to me this last night.
Make it into a component before you draw other stuff touching it..
Another way is to draw what you want to make into a component away from
everything else, make it a component and then move it where you want it.
Barring those, you could use layers...draw one thing on a new layer...draw
something else on a different new layer. Hide either layer and you can
easily select what's left to make it a component. Making components as you
go is easier
Although Layers can be handy (and essential to work flow in modeling
construction/fabrication projects), be aware that Layers can cause major
frustration, especially if you start the practice of drawing on specific
An essential rule to follow, and the absolute best way to use Layers
when modeling in SU, is to first assemble your geometry into either
groups and/or components on Layer 0, and then assign those, ONLY after
they have been grouped/made into a component, to a specific layer.
As familiar as I am with SU modeling on a daily basis, I occasionally
get bit by this and it can be difficult and time consuming to correct,
even on even small, uncomplicated models; and especially deadly on
complicated models with lots of groups and component parts.
Here, found this that explains it quicker than I can type it. Copy it
somewhere and put it your saddlebags for later, you will be glad you did:
How To Avoid Problems with Layers in Google Sketchup
(by Adrian Chopra)
~ Do all your modeling on Layer0. Keeping all your loose geometry
(that’s not part of a group or component) together in one place is the
only way to make sure that you don’t end up with edges and faces all
over the place. SketchUp, unfortunately, lets you put geometry on
whatever layer you want, which means that you can end up with a face on
one layer, and one or more of the edges that define it on another. When
that happens, it’s next to impossible to work out where everything belongs.
~ Don’t move anything but groups and components to other layers. If
you’re going to use layers, follow this rule: Never put anything on a
layer other than Layer0 unless it’s a group or a component. Doing so
ensures that you don’t end up with stray edges and faces on separate layers.
~ Use layers to organize big groups of similar things. More complicated
SketchUp models often include things like trees, furniture, cars, and
people. These kinds of things are almost always already components, so
they’re perfect candidates for being kept on separate layers.
~ Don’t use layers to organize interconnected geometry; use the Outliner
instead. Interconnected geometry means things like building floor levels
and staircases. These model parts aren’t meant to be physically separate
from other parts like vehicles and people are.
~ Feel free to use layers to iterate. Iteration is the process of doing
multiple versions of the same thing. Lots of designers work this way to
figure out problems and present different options to their clients.
Using layers is a great way to iterate: You can move each version of the
thing you’re working on to a different layer, and then turn them on and
off to show each in turn. Just remember to follow the rule about using
groups and components only on separate layers (mentioned previously),
and you’ll be fine.
As one who uses Layers in every model, I can't emphasize just how
important it is to follow the above guide lines when working with layers.
As has already been mentioned, you can use triple clicking to select all
of the connected pieces of your panel. If the things that are around
your panel are already components then they will not be selected when
you triple click on the panel.
If I understand the question, yes. In my understanding, basically it is the
copies of groups that add significantly to the overhead. If you only need
one brick in your model, making it either a group or component won't have
an impact. But if you need a thousand, making it a component instead of a
group will reduce the overhead. IME, the file size issue is less noticeable
than the impact on performance.
Ok. So I guess it is best to hold groups to a minimum.
I wonder what advantage there is to using groups rather than components
other than having an additional number of named components in the drawing.
Nothing wrong with that ... AAMOF, that is exactly how "Dynamic
Components" are made, with "nested" components.
IOW, a "DC" Base Cabinet is a component, comprised of sub components for
the stiles, rails, end panels, etc.
This allows them to be re-sized programatically while maintaining
certain dimensions, as well and axis positions.
IOW, the component "rail", inside Dynamic Component "Wall Cabinet" (a
collection of its (nested) component parts) can be re-sized (SCALED) in
length, without affecting it's width and thickness, as well as it's
relation, in axis, to other component).
Try to "scale" with a "Group", which can't be programmed to be dynamic,
and all the parts will change in dimension in proportion to the amount
of "scale" imparted.
You may remember that one of the first things I did when I got the Pro
version of SU was to immediately start programming "Dynamic Components"
for kitchen base and wall cabinets so I could populate existing space
for both new construction and remodeling without having to draw
different sized cabinets.
While these initial dynamic components are still handy for my use, the
sketchUp 3D model world is now full of these things, most sophisticated
way beyond my programming abilities/time to mess with it.
You already know this, but for those paying attention to the thread
looking for more information, the below will be helpful to save for
their future use.
(Don't know where this came from/who to attribute to, but it is in my
SketchUp EverNote file):
A collection of faces and edges within a model that are isolated from
other parts of the model.
Anything protected in a group cannot by affected by any geometry outside
of that group.
To manipulate faces or edges within a group, or to add geometry to a
group, that group must first be “activated” by double clicking on it.
If you draw a shape on something that is in a group, it won’t “stick” to
the object unless you open the group first.
Groups can contain “loose geometry”, guides, section planes, dimensions,
text, or other groups.
Groups can be manipulated as an assembly. (Move, rotate, scale, paint,
Groups have their own independent 3-axis from the rest of the model, and
it can be reoriented
Copies of groups are independent from one another. Once a copy is made,
any changes made to one instance of that group do NOT affect the other
copies of that group.
Similar to groups, except that each copy of a component remains
identical to its original. Any changes made to an instance of a
component are automatically reflected to each instance of that component.
Using Components for multiple copies of the same object within a model
increases the performance of Sketchup when compared to using groups to
do the same thing. That’s because Sketchup only has to define a
component one time, whereas with groups, Sketchup has to define each and
every group even if each group is technically identical.
Components can be saved independently from the current model and
imported into other models. If you make any changes to the component,
you can update the reference in any models you’ve imported it into.
You can assign a “gluing plane” to components. A gluing plane allows the
component to automatically orient itself onto the face of the object you
are moving it to. For example, if you had a component of a picture
frame, you would want it to be placed flat on a wall. Depending upon
which wall you place the component on, you would have to rotate the
picture 90° and reposition it onto the wall. By defining a gluing plane,
the component will automatically rotate as you move it so that it is
oriented properly to whichever wall you are moving it to.
Components can be configured to “always face the camera”. When you first
open Sketchup, you’ll notice how the person inside every default model
always faces you, even as you orbit around the model. You can assign
this property to components too.
If you want to make an instance of a component unique from its
counterparts, you can right click it, and select “Make Unique”.
