JTB Quick Perspective will transforms Points, Lines, straight Polylines and "landscape" Blocks to perspective view drawing, all in 2D working space.
If you want to add some simple perspective view to your drawing without getting involved in complicated 3D modeling, you will find JTB Quick Perspective invaluable. All you need is one command and you will be taken through a simple procedure where you will control required extrusion and rotation. Newly created objects are polylines and can be used as source frame for the next command call. With JTB Quick Perspective you will create 3D-like perspective views with just a few clicks!
Note: "Landscape" block should have insertion point at the bottom.

Use the AutoCAD app installer that also puts a button on the Plug-Ins or Add-ins Ribbon tab.
The command to start the program is JPP.
Select a trapezoid polyline as frame. Then select lines, straight polylines and landscape blocks as source objects. You can select a series of another trapezoid polylines as destination frames, or using directly the current one.
Type R to rotate frame direction. Type F to flip direction. Type X to generate extrusion. You have 2 extrusion options: extrude as Solid, or just extrude Plan only.
3 point perspective view
This plugin is a gift to drafters who love classical descriptive geometry, where the built-up of a 3D object's perspective view on 2 dimensional canvas will be like this:
The above schema is called 3 points perspective view, where:
+ Parallel lines will find each other at infinitive point called "vanishing point".
+ Ground plan and all of its parallel lines and plans will expand to infinitive line called "horizontal line".
We will start with a simpler case: 2 points perspective view:
2 point perspective view
Our target is to transform a normal plan to a perspective plan. Using JPP command, you can do it as easily as follow:
+ Click to select the source frame of your source plan
+ Select the source objects
+ Click to select the destination frame of the perspective plan.
+ In a second, a perspective plan will be created. You can type R to rotate it around if 2 plans are not aligned.
Note 1: You should manually set up your drawing (the horizontal line, the vanishing points,etc.) before using the command.
Note 2: 2 frames should be draw in the same direction: clockwise or counter clockwise.
How to do it?
Let's start from the "atom" procedure: transforming a point from a normal plan to a perspective plan:
Denote O, A, B points as the coordinate system.
Denote X and Y as point P coordinates. We got to find the equivalent X and Y on the perspective plan.
In perspective plan, ratio OX/OA and OY/OB are not the same as in the source plan, except in case they are horizontal line. Therefore, we got to draw an additional horizontal line go through O to transfer the ratios. We will find X0 and Y0 where:
+ OX0/OA0 = OX/OA (source plan)
+ OY0/OB0 = OY/OB (source plan)
Notice this is 2 points perspective view. Line V1-O, V1-X0, V1-A are parallel. Line V2-O, V2-Y0, V2-B are parallel.
Hence, our transformed point P will be found at intersection of line V1-X0 and line V2-Y0. Problem solved.
JTB Quick Perspective command
Rise from the above "atom" procedure, JPP enabled you to transform drawing from any source plan to any target plan, as image shown below:
Once a 2 point perspective drawing is done, type X and the command will help you make the extrusion. Objects can extruded from ground plan or from any plan by selecting the third vanishing point. The final result is a complete 3 points perspective view.
- 2017-02-06 - version 2.5
- Enabled to generate "landscape" blocks.
- Added "Flip" option.
- Fixed issue when working with UCS.
- Fixed one bug bug when you select objects including circles, arcs or something that not supported, then at running flipping and rotating, it keeps erasing wrong objects around.
- Fixed one bug when transform blocks to a trapezoid quadrilaterals. Transform blocks is a feature added at last. Then bug happen there when parallel lines does not intersected.
- Works with all Autodesk® AutoCAD® products.
- version 2.0
- Enabled Rotate frame direction.
- Enabled Extrusion.
