nanoCAD Mechanica23 platform support nanoCAD, as well as vertical solutions nanoCAD versions 2, 3, 4, 5, 6.

If the drawing is created nanoCAD Mechanica23, it opens on a computer that does not have any one of the modules of the complex, the special objects nanoCAD Mechanica23 converted into so-called proxy-objects. To preserve the ability to edit them using "handles", as well as view and change the objects in the dialog box "Properties" on a computer, you must install a freeware distribution nanoCAD Mechanica23 Enabler, located on the CD with a licensed copy  nanoCAD Mechanica23.

When transferring files to a user or customer drawings that do not have nanoCAD Mechanica23and not having the ability or desire to use nanoCAD Mechanica23 Enabler, you need to convert all the objects nanoCAD Mechanica23 in the standard system primitives  nanoCAD.

To do this, use a special command CAD drafting Basic knowledge 0"Break all objects" (the toolbar "Edit"). This command will automatically select all of the objects in the drawing, and divides them into primitives nanoCAD. For individual subdivision nanoCAD Mechanica23 - objects can use the standard command nanoCAD "EXPLODE".

In the dialog box nanoCAD Mechanica23 - Setting possible as a random location nanoCAD Mechanica23 - objects on any current layer and automatic fixing nanoCAD Mechanica23 - objects on said layer. In the second case, creating nanoCAD Mechanica23 - subject to pre-select the desired layer in the list and make it current is not required: the program will automatically execute it, regardless of the current layer.

Option 1. Making projections in model space

Suppose the principal species in the model space are performed one by one.

Additional types, sections are made with scale factors other than the main species.

Features insert frame

When placing a border with a title stamp in model space given its scale relative to the principal species. Frame increases or decreases.

Features design drawings

When dimensioning must take into account the scale factor drawing (the value of the dimension text, the value of the arrow, spacing, etc.) and numerical designations for each species.

Assume frame is increased with respect to the main sight 10 times. In this case the arrowheads, dimension text height and other text labels should be increased by 10 times. A nominal size of the text for the main species should be marked on a scale of 1:1.

When applied to the kinds of sizes, made in a different scale (in our example, 1:20), nominal size must be multiplied by a scaling factor.

CAD software Basic knowledge 13

Example of projection drawing frame, increased 10 times

3. Configure the available options.

CAD software Basic knowledge 55

4. Click the "OK" button. The hatching will be adjusted and added to the appropriate location.

Jobs in the current scale

The nanoCAD Mechanica23 uses the concept of the current scale. The current scale is different from the current global proportions, expressed in units (units).

Scale objects made depending on the setting of "Use the global scope to design elements" (see. Customizing the appearance / General settings / Registration)

If the value of this setting - "Yes", the dimensions are scaled design elements and standard elements nanoCAD Mechanica23base data types defined by the appropriate scale lines.

CAD drawing Basic knowledge 56

CAD drafting Basic knowledge 57

This setting is useful when drawing in model space on the scale of 1: 1, followed by design drawings in paper space viewport on an appropriate scale. In this case, design elements will appear consistently in viewports with different scales.

If the "apply globally to design elements" is set to "no" to the size of standard parts varies in accordance with the scale and size of the design elements remain unchanged. In addition, there is a linear scaling sizes by setting a linear scale factor.

This method is used when plotting the initial scale model other than 1:1.

CAD software Basic knowledge 58

The scale of the database objects of standard products and design elements can be installed with the help of the scale.

CAD drawing Basic knowledge 59

In the absence of selected objects using the zoom panel zoom button or change the current zoom scale drawing.

If you have selected objects, the button and the panel scale display their scale. Zooming only affects the selected items without changing the current scale drawing.

The program features the ability to zoom the selected object nanoCAD Mechanica23 center of the screen as a display frame around the object (the default frame is disabled). To do this, move the cursor to the object that appeared "Overall corners", hold down the SHIFT key, click on the right mouse button - will automatically increase the screen of the selected object.

If you press on an object at the same time the right mouse button and SHIFT key returns to the previous display with automatic centering of the object on the screen.
