i just got norlings perspective made easy. perspective is tough ****.
im sure its way off.
You have got to decide before you start a perspective drawing whither it is 2pt. or 1pt. perspective and draw in your vanishing points. In your drawing it looks that you have been caught between the two. As your plane/car or what ever the model is your perspective going left looks right but the top surfaces going right are wrong. Have a look at the file I have just started it. I took one of your guides which was going right and I extended it to get the other vanishing point VP2. Do a Google search on this subject and there is one cool site aimed at Adobe Illustrator and it gives tutorials. What I would say is that this perspective would be better done using measured perspective which is another ball game to do on a computer with a graphics programme you would better to use a CAD programme or do it quicker with pencil and paper and a few drawing aids.
Here is the tutorials that I was mentioning: http://www.khulsey.com/perspective_basics.html
They are hard for the model that you are using!
You can do a rough (like simply drawing lines of pespective as a grid) or do detailed drawing using Google SketchUp Free. You can export the result to a PNG or JPG and import that into Xara and then draw over the top of it. Or, simply, open both SketchUp and Xara and toggle back to SketchUp to reference the proper perspective. SketchUp may also have vector DXF and PDF exports; the PDF you can open in Xara and the DXF you'd have to import into another application to create a Xara friendly vector format.
no it doesn't look right.
Sorry it has taken me so long to do my perspective tutorial.
I've got to get the lead out.
I'm part way through but when it comes to the written part I have a hard time
Sorry for the delay. You have given me some ideas of what is giving you problems that I may be able to clarify. Even though my tutorial is from the standpoint of doing them my hand. It's on the way soon though.
Actually, it may look closer than you think. BUT IT DEPENDS UPON THE ACTUAL SHAPE YOU ARE TRYING TO PORTRAY.
Here you see the shape I thought you were trying to visualize in the orthographic views and a 4th perspective view close to that of your original image.
So it is not just getting the perspective and viewing angle correct but understanding the geometry in that perspective.
As a starting point, you might want to show us some orthographic views of the shape you were trying to put into perspective.
I did this in SketchUp in less than 5 minutes (I used your image as a backdrop for comparison).

I am not an engineer or achitect.
I found that programs like SketchUp helped me visualize what a perspective should look like (it even has a option to view in traditional 2-Point perspective, see below attachment).
It can be tricky understanding how a bending pipe, the intersection of cylinders, and non-symetrical shapes should appear in perspective. Sometimes even a "minor" error can easily be seen and keep your illustatration from looking its best. Unless you have a photograph or computer application (or a good how-to-sketch book) to use for a comparison, it can be frustrating.
Practice is important.
i think i see my mistake after reading about 1 point perspective. the mistakes i see in my drawing are, 1. my drawing doesn't know whether its 1 pt or 2 pt perspective. 2. its impossible to be just 1 pt because all 1 pt perspective end at a single CENTRAL vanishing point. making my far left 1 pt drawing impossible. 3. adding a second vanishing point, makes 2 pt happen, and it doesn't matter whether the two pts are equally spaced as the father left or right a point is the more the object is being turned, or the view is being panned. is this correct. i think ill star with 1 pt for now.
is this better?
i think i got this boxy perspective down but how do you over lap boxes? its kinda boring just using simple boxes. what i mean is, i dont want to draw just flat boxy shapes but want to overlap shapes. you know so either a top or bottom shape overlaps so when the top shape is over the bottom, it overlaps and does go down into one straight line.
Just carry on in the same way.
You can use the mold tool to divide space correctly. Works with circles as well.

is this how you would use the mold tool for perspective? can the mold tool do 2pt or 3 pt perspective? is the mold tool effective at perspective? any tips on using the mold tool for perspective?
Here's an example of using the perspective tool (mould tool) to create a perspective 3D shape.
From memory what I did was something like this:
* Draw horizon line
* Below the horizon line, draw shape in plan, including things on different levels, group
* Rotate group so that the part you want to face you is at the bottom
* Apply Perspective mould and drag the vanishing points so they're on the horizon line (they don't snap unfortunately)
* Draw a short section of horizon line on top of the first and group with the perspective mould
* Now drag the bottom selection handle so that the group squashes vertically. As you drag it the horizon remains fixed and the shapes appear to "extrude" a vertical volume.
* Drop copies of the squashed group by right-clicking as you drag at appropriate heights.
* Now use those shapes as guides to tell where interesting points are in 3D perspective space and just join the dots.

WOW. um i don't think i can do that. its good work though.Quote:

i hope im not being a nuisance posting all these pics and asking all these questions. i really do want to get better at art. ive had xara for over a year now since x1. ive only been seriously devoting time to it for about a week now(and while it may not be much) i know more about xara now then i ever did. i really do want to improve but i don't expect miracles.
Phil, thanks.
Any chance of doing a video of the procedure? It might be easier to follow.
Regards

Not sure if this is going to help, as you seem to be already getting plenty of help. But, when I'm doing anything with perspective I use the 3d tool to draw a reference object that I can then determine the prespective for my drawing from. I then draw guides on the guide layer and they act as a reference when constructing my image.
I've attached a crude example of a drawaing of an object that follows the same perspective rules as my reference rectangle.
Sorry, I haven't got enough time to make a video. Maybe somebody else can create one.

It would appear that the offset you have on the front is what is giving you the most trouble. For better or worse I am humble submitting my xara file which is hopefully a corrected perspective and a ping of what I did. Until I manage to get the tutorial finished maybe this file will suffice. In the mean time I will try and set this up as a 2 point projection and make a mini tutorial from that. If you have any questions feel free to ask.
I must admit I am skittish about submitting this for fear that maybe I royally screwed up somewhere, but I hope this helps
Well my worst fears were realized. I messed up, for some reason I thought you were tapering the front in toward the center which made no sense. So here is a revision and my humble apology.
Edit: and this time I didn't make it semi-transparent to show what you had and what I did.
