How to create a perspective view

fredougelinas — Fri, 27 Mar 2020 12:05:39 GMT

Hi,

I'm an architecture student and I have to realize a 2d perspective view of a 3d building I created, and I don't know how to do that and don't find any information on internet that helps me to do so. My teachers use Autocad for PC and so they are using the camera function to create that view, and as this feature doesn't exist on AutoCAD for mac, I don't know how to do it. For example, they are changing the coordinates of the view so that the Z coordinate is at the height of the viewer (human being, about 1.7m), and I don't get how to do it with the DVIEW (or anything else). I have to create a perspective view and then transfer it to the layout and I don't get how to do that neither.

Can someone help me ?

Thanks in advance !

You're limiting your abilities by not using the exact software: get Windows installed on your MAC, get the Windows software your instructor is using, and follow correctly. It's not that hard, no need to start crippling your education already.

Apple has a good process outlined, here is the link https://support.apple.com/en-us/HT201468

Ask a computer-savvy friend or your school's IT folks to help if you feel more comfortable.

First of all, draw a help line from the desired viewer's position to the desired target's position.
Select it, go to the PROPERTIES PANEL and set the ELEVATION value to 1.7m (viewer’s height).

Type DVIEW, select all the building’s objects you want to be shown except the help line and press ENTER.
Type POINTS, click on the line’s end point to set the target's position and then click on the opposite start point to set the viewer’s position.

Type DISTANCE, enter a value in meters to adjust how far is the viewer from the building and hit ENTER.
Type ZOOM, enter a value in millimeters to adjust the lens focal lenght and hit ENTER.
Press ENTER once again to exit the DVIEW command.

Finally, in order to save the generated view, type VIEW and hit ENTER.
Type SAVE, press ENTER and input the dessired cammera name i.e. CAMERAFRONT.
You can restore the saved view anytime by typing again the V command followed by the RESTORE option.

Hi Frédérique,

I attached AutoLISP file which can help you to work with DVIEW command (create camera view).

Use APPLOAD to load it, then use SET_CAM command to create camera view.

The routine will:

- set view to plan

- ask for camera point location in plane

- ask for target point (view direction)

- ask for camera level above current UCS (or WCS) plane

- ask for camera focal length (lower values will give you wider view angle)

- create perspective view (camera view)

Hi !

Sorry for the late answer, I didn't get the chance to try before now. It seems to be working ! I would still have some questions though.

1) Every time I close the Autocad, I'm losing the uploaded application you sent me. Is there anyway way to keep it forever ?

2) I didn't get what you mean by "Set view to plan" ?

3) Could you tell me why the colors don't appear like I chose them ? For example, I have some white walls that appear dark grey, and my light grey is so dark that you don't see anything. Is it possible to fix that and have the "true" colors ?

thank you so much !

Hi,

1/ You can use Startup Suite to force AutoCAD to load AutoLISP routine in each drawing automatically:

3/ That is because Perspective view background, I think. Can you attach screenshot of the issue?
