This example is meant to demonstrate how you create a ground plan. Going
through this tutorial you will try several wall functions. Using the
dialog boxes you can edit the height measurements of the walls. Later
on you can look at and correct the height measures in the various
projections.
Before you begin, you choose from the menu Project the
item New in order to erase all elements which might be in the
drawing area. If you start drawing a plan you do not need to decide in
which scale your drawing shall be designed. The decision about the final
scale of your drawing will be made if you do the output to printer, etc.
This means that you always draw in the scale of 1:1. Choosing a scale in
the view menu is just meant to display the drawing elements on your
monitor in different detail enlargements. The garage shall have the
external dimensions of 4.99m to 6.99m, the outer walls measure is 0.365m
and there will be a garage door and a window. To start with, choose from
the function list Wall the item Wall and select the scale
1:500 (in the view menu underneath the drawing area).
|
The 1st wall :
About in the middle of the drawing area you situate (watch the
help bar below the drawing area) the "1. Corner point:" of
the first wall. Confirm this point using the enter key, or you
snap-to the same point with another mouse click, the Snap must be
activated. The "2. Corner point" will be placed exactly upon the
first one. Now, you enter the length of the wall using the keyboard.
Hit the cursor right key "X+:" and you enter "4.99"
m. One enter moves the cross which marks the point the distance
you entered. Then, you define the thickness of the wall. Hit the
cursor down key and move the cross "0.365"m downwards. One
enter moves the cross and you confirm the point with a final enter.

Test the view menu
Choose Zoom. Define the range of a new detail enlargement
positioning two points. So you set two points, in a way that the wall
will be within the range of the two points.
Further on, try ->. The detail enlargement will be moved the
distance you enter with two mouse clicks. All functions in the
view menu can be activated while entering or altering drawing elements.
If the display function is terminated, you may continue entering
drawing elements.
Back to the garage:
Activate the buttons + and - of the view menu until the
scale 1:100 is displayed. Now you select the scale button (the
one in between the + and the - ) and position the center point
of the new detail enlargement upon the wall.

The 2nd wall : Snap-to the lower left corner point of the first wall. Confirm the
"1. Corner point". "Move / Confirm:" Move the
second corner point downwards entering "6.26" m and now
move it to the right entering "0.365" m. After that, you
confirm the lower corner point of the second wall.

The 3rd wall : Copy the second wall to the right. To do so, choose from the
main menu the menu list Edit, then select the item Copy.
Instead of the function list the selection menu appears. All items
for selecting elements are displayed. Use the options Active
and Element in order to activate the second wall. Active
elements are displayed white. You confirm the activated elements
clicking on OK. Now, you need to enter the distance where to
move the copy of the wall. Help bar: "Move/Start point:"
Snap-to the upper right corner point of the active wall. This
shall be the start point. Position the "End point:" of the
distance at the lower right corner of the first (horizontal)
wall. You confirm this point and you finish the copy-function
aborting it with the right mouse button somewhere outside of the
drawing area, or choose another function right away.

The 4th wall : Again, choose the function list Wall, then select the item
Side. Now, have a look at the walls` dialog box. Click the
item with the ? in its` button. Here you enter the preferences
only concerning the wall elements. The name of the active dialog

Have a look at the dialog window:
Choose one of the prearranged preferences; or you may enter your
own preferences. Try pen color blue (ink pen, about 0.35mm) and the
line. The wall thickness should be 0.365m.
|
The "start point:" needs to be situated upon the lower right
corner point of the second wall. The end point shall be the
lower, left corner point of the 3rd wall. So you also snap-to that
point and confirm it. The help bar: "Select Side:" You select
the outer side of the garage. After this, the wall thickness
will be added, which was defined in the walls` dialog box.

The display of the last wall in the drawing area is not
correct: To fix this, you choose the item in the view menu
which looks like a sheet of paper.

To do so, you choose further down in the walls` function list
the item Join. Now you click using the pointer looking like a
diagonal cross hair onto the second and the fourth wall. They

To achieve this, you choose from the walls` function list the
item All, you find it right below Connect. Automatically all
wall endings will be connected of all those walls which have
exactly matching corner points.
Now have a look at the walls in a perspective view. Choose from the menu
3D one of the arrows. If you entered the walls with height and
base entries in the dialog boxes, then you will see your first perspective
view.
Garage door : Select the function list Opening. Here you
start having a look at the dialog box of the openings. Click
underneath the item Opening on the button with the ?. The symbol
of the garages` door opening should be arranged without a stop and

The door : This opening shall be entered positioning two points,
which means with a start- and an end point. Therefore, you deactivate the

mouse looking like a diagonal cross hair onto the lower, horizontal wall.
Now you need to enter the exact location of the opening. To achieve
this, you snap the inner lower left corner of the garage. From there you
move the start point of the opening about X+: 0.375 towards the right.
Now you snap the inner lower right corner and you move the end point
about X-: 0.375m. If you now look at the coordinate display, it should show
"X: 3.5100" and "Y: 0.0000". If this is displayed
you confirm the entry with a final enter. Finally, you select the outer
side of the wall. And the openings` symbol you have chosen from the

the input options mentioned in this tutorial. The way you get
close to the aspired point using reference points and using the
additive numeric input shall simulate the way you would proceed
if you would draw by hand. Confirming each step of input offers
you to combine the different CYCAS input options.
