Thanks to the increased level of compatibility, you can come across a number of features and interface elements that provide effective help in case you have worked in other CAD environments so far. The following tools are available for this:

**The comma as separator**

You can use the comma as separator for coordinate inputs. For this you have to switch off the Comma (,) in Decimal point allowed option in the File menu -Options - Units and angles

For example if you want to draw a line from point X=0; Y=0 to point X=3; Y=4, it is enough to do the followings:

- Start the line drawing command.
- Type 0, 0 (0,SPACE0) and press Enter to specify the coordinates of the start point of the line.
- Type 3, 4 (3,SPACE4) and press Enter to specify the coordinates of the end point of the line.

By switching off the option the comma (,) is interpreted as a separator instead of a decimal point. Use the dot (.) character for decimal point.

**Absolute coordinate input**

You can specify relative or global coordinates. Set the Global / Relative coordinate icon in the status bar to global. In case of absolute coordinate input the syntax is the following: X,Y ENTER. In that case the global origin is taken into consideration and the coordinate input is relative to this point. The symbol of the global origin is represented as follows:

**Relative coordinate input mode**

In case of relative coordinate input mode the syntax is the following: @X,Y ENTER. In that case the last specified point is taken into consideration and the coordinate input is relative to this point. Use this possibility if it is easier to specify a point relative to previous point than specifying the global coordinates.

The Relative coordinate input mode is represented as follows:

If the Global / Relative coordinate icon is set to relative, it is enough to use the X, Y ENTER syntax for the coordinate input.

**Polar coordinate input**

Often you know only the angle and length values. In that case use the polar coordinate input. It can be very helpful if you wish to draw a line with a length of 2.53 m and an angle of 32°. You can specify absolute or relative polar coordinates as well.

**Absolute polar coordinate input**

In case of absolute polar coordinate input the syntax is the following:

numR<numFi, where

numR is the distance from the global origin,

numFi is the angle.

Use this input method when you know the distance and angle relative to the global origin.

**Relative polar coordinate input**

In case of relative polar coordinate input the syntax is the following: @numDir<numFi , where

numDr is the distance from the previously specified point,

numFi is the angle.
