Compare manual and cad techniques

2. Draw lines connecting the outer arcs as well as the lines constituting part of the keyhole. 3. Clean up the drawing by trimming lines that are not accurate or those used for construction. 4. Group appropriate elements in the two dimensional drawing and project them into the third dimension.  · One of the best parts of CAD designing is that you have the same simple tools that we all use on our computers every day: cut, paste, copy, and delete. These have virtually no learning curve at all. 3. CAD designs can be replicated almost instantly. With CAD software, you can create as many copies of a design as you like.  · Comparison of CAD and manual sketching tools for teaching architectural design.

Many studies generally acknowledge design as a learning domain, in which past experiences and basic techniques are big contributors.

Advantages And Disadvantages Of Computer Aided Design (CAD) Over Manual Drafting. The advantages of CAD include: the ability to producing very accurate designs; drawings can be created in 2D or 3D and rotated; other computer programmes can be linked to the design software. With manual drafting, you must determine the scale of a view before you start drawing. The purpose of this study was to investigate the comparativ effects CAD and. manual drafting have on the effectiveness of teaching technical drawing techniques to secondary students, The problem of the study was to compare CAD and manual methods. With manual drafting, you must determine the scale of a view before you start drawing. This scale compares the size of the actual object to the size of the model drawn on paper. With CAD, you first decide what units of measurement you will use, and then draw your model at scale, should one of the main benefits of CAD.

The objective of this research is to conduct a comparison in pattern and marker making between the CAD and manual methods as regards individual course steps.
