autocad 3d objects moved on opening drawing

Topics covered in this Lesson:

Viewing Objects in iii Dimensions, Tiled Viewports, Perspective Views, 3D Orbit

AutoCAD has a few ways for y'all to view an object other than the plan view that you lot have used for your 2-D drawings.

NOTE :
At present is a proficient time to change into the 3D Basics Workspace. Click the 'gear' icon on the status bar and select "3D Basics".

When y'all are in the 3D Basics workspace, your tool palettes on the ribbon will change. This will make it easier to observe tools and icons that y'all'll utilise more than oftentimes in 3D.

The kickoff one we'll expect at is the Visualize Palette.

>

I detect this is the quickest mode to learn the different views, and I'll show another way in a minute, but for now this is the fastest and clearest way to see different views of your AutoCAD objects in 3D.

Open this DWG file and then nosotros'll wait at it from a few different angles.

When you lot start open up it, you'll see the drawing from the programme (top) view looking straight down the Z centrality towards the origin. You'll see the 10 axis in its familiar location with positive to the right and the positive Y axis pointing up.

Using the Visualize tools shown above, select the Bottom View. You'll at present exist looking upwardly from the Negative Z axis towards the origin.

Find how the Positive Ten axis is now pointing to the left? And information technology'south backwards? You're looking UP at present instead of DOWN. It'due south simple to see in this example, simply what if you were looking at a cube? (It would wait the same from summit or bottom.) Take a expect at your UCS Icon - check its orientation, considering even if you view changes, your UCS / WCS doesn't necessarily change with it. This is REALLY important to pay attention to when you start drafting in 3D.

Try a few other views from this list like the SW Isometric view, then return to the Height view.

Tiled Viewports

At that place volition be times when y'all may need to see around to the other side of your object. Then y'all can easily use the other preset views to see your model. You tin can also have more than 1 view on your screen at a time.

To achieve this, use the Viewport Configuration option of the Visualize tool palette and select the "4: Left" selection. Whatever view or viewport configuration can exist saved under a unique name. Later you tin can easily restore this view when needed. Here are the preset viewport configurations that y'all can utilize in model space.

Change the view by picking in i of the viewports and selecting a new view in the droplist. See if you tin get this same configuration in your drawing.

Here are a few general notes about views and viewports:

You can have viewports in either model space (tiled) or paper space (floating).

They tin have different zoom ratios.

There is a difference betwixt views and viewports.

If you go to a lot of piece of work to get a view you demand, save it using the VIEW command.

When saving a view, requite it a descriptive proper name.

Keep an eye on the UCS icon in the corner of the screen or viewport.

The smaller your monitor is, the harder it is to see tiled viewports.

When you have more than 1 viewport, click inside the ane y'all want active.

Change back to a single tiled viewport and go to the peak view. On the right your screen you should see the "View Cube" This is a quick tool that lets you change your view with a click or 2 using a visual cube for reference and orientation.

To use the View Cube, you can click on different sections of the cube or on the directional messages. You lot can likewise select a corner of the View Cube to modify to isometric views. In the example below, the highlighted corner volition give you the SW Isometric view.

If this is confusing, that's understandable, but observe how the highlighted corner is between the W (West) and S (South) views? Click around on the cube and come across if the views you get are what you are expecting. Over again, it will take a while to be comfortable viewing in a 3D world (on a 2d monitor).

For more practise viewing your 3D drawing, open up up this sample 3D file of a table and chairs. Change to different viewport layouts every bit shown above. Try some of the different Isometric views. Depending upon the size of your monitor, it may not exist practical to use multiple viewports. In the stop it is a affair of personal preference that decides what setup yous are comfortable drawing in.

When you're finished exploring, change back to i viewport and switch to the SW Isometric view. As well, if you need to, alter to second wireframe in your Visual Mannersouthward tool palette.

Prespective Views

At that place is another control called DVIEW (Dynamic View) that gives you more than control over the view of your objects. It will besides let y'all to meet a perspective view of your model. This can be a very confusing method if you don't have a system. What follows is my approach to creating perspective views.

The basis of generating a perspective view is to have a virtual camera and target. Retrieve of where you lot would similar to 'stand' (the camera) and what management you want to await at (the target).

In this example, I want a view that gives me slight perspective view of the table and chairs. The first matter I need to exercise is draw a signal for my camera location.

Draw a line from the center of the bottom leg 6' in the negative X axis. At present draw a line 5'6" straight up (@0,0,v'half-dozen) and finally draw a line to the middle of the far end of the table. It should look similar this:

Now showtime the DVIEW control. You volition be asked to select objects. Yous can select everything, or for the purposes of setting points, I would ordinarily simply choose the line as information technology makes the command faster in large drawings.

Start the control and then select the line. Y'all'll accept a agglomeration of options on your command line now, simply you want to select POINTS (PO). This allows you to select a target and a camera, AutoCAD will aim the photographic camera at the target and give you lot a perspective view. Follow the steps below to endeavour this out.

Control: DV DVIEW
Select objects or <use DVIEWBLOCK>: <SELECT THE LINE> 1 found

Select objects or <use DVIEWBLOCK>: <ENTER>
Enter option
[Camera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/Hibernate/Off/Undo]: PO <ENTER>

Specify target point <84'-0", -113'-7 ix/16", 4'-2 7/16">: <PICK THE ENDPOINT ON THE RIGHT (TARGET)>
Specify camera betoken <66'-10 11/16", -130'-viii 15/16", 21'-three thirteen/sixteen">: <Pick THE ENDPOINT ON THE LEFT (CAMERA)>
Enter choice
[CAmera/TArget/Distance/POints/PAn/Zoom/TWist/Prune/Hibernate/Off/Undo]: <ENTER>
Regenerating model.

Start the DVIEW command again and select all the objects. In larger drawings, select the objects that are furthest to the extents of the drawing (this will relieve time and let you know the limits of your view) and whatever objects that are critical to your view. What this means in that if you are using the control on a very big drawing, the DVIEW control can dull down your system to a crawl. Past selecting only the ones on the exterior limits of your cartoon, you will still exist able to employ the control quickly and efficiently.

This time, choose the Distance option by pressing D <ENTER>. This option effectively zooms in and out while in a perspective dynamic view. Move the slider at the top until it is just correct of the '1x' and so left click with your mouse. Notation that slower computers volition take longer to regenerate the drawing for you. You tin besides enter distances manually on the command line - try this out too. Each 3D model volition require unlike settings to get the view you want.

While still in the Dview control, type in PA for the Pan pick and motility the tabular array and chairs upwardly slightly in the cartoon expanse so that they are centered.

And lastly, blazon in H for the hide choice for a more than realistic view. and and then printing <ENTER>.

To preserve this view that you worked then hard to attain, type in V (for view) and select the New button and give your view a name and press OK. Now when you need to go back to this view you merely type in Five once more, select your named view, printing the Prepare Current button and press OK. Your new view is as well added to the top of the list in your View Tool Palette.

If you are using this command on larger drawings, like a abode or edifice, the same process is used, but you should create the camera location to be further away from the objects y'all desire to view. Practice makes perfect and this control can take some trial and fault sometimes to get information technology just right. In the finish, information technology is a very powerful viewing tool. When practicing, relieve views and then you tin go back to them if needed - it will save you lot a lot of time.

3D Orbit

Another way of viewing your objects is to use the 3DORBIT control. This volition give you lot a gratuitous paw to rotate your cartoon around in space. Type in 3DO <ENTER> and y'all'll see that your cursor changes and yous can start rotating your objects around freely by clicking and moving your mouse. Y'all can always reset your view as yous learned higher up.

This is a handy way to quickly view your drawing and see if there is anything that doesn't look 'quite right'. You might find lines that snapped to the wrong OSnap or other errors using this command. When information technology comes to generating views, I still recommend the DVIEW command and then that y'all accept more control over what your view will look like.
