Revit Tutorial

Check this out: Revit Tutorial 

This is a video clip in YouTube  showing step by step procedures on how to get started in Autodesk Revit. It is very useful indeed.

It is a series of about 3 minutes video clips which just make it easier to follow as oppose to long video clips which can be tiring and loaded with too much information.

If you want a free software of Autodesk Revit, you can download the student version of it. If you are not formally enrolled in a particular school, you can opt for the "home study" option. The software will be valid for about three years.  You will have plenty of time to peruse and learn the program.

Good luck. If you have any queries, try me, just post a comment and maybe I can help. Thanks for visiting my website.

Here's below is an image of my work. It is actually a work in progress, still lots of thngs to improve.

Free Structural Design Software

If you can design by hand then you can do structural design using any computer software.


The first step in doing so is to define your frame or your structural element, e.g. beam and column.  You can do this simply by using 3d coordinate system.


For example, if you have a simple frame with two supporting columns and one beam at say three meter each, then you can start your definition by assigning 0,0,0 coordinate for the base of your first column, then 0,0,3 for the top of first column and end of the beam. Then 3,0,3 for the other end and top of second column and then 3,0,0 for the base of the second column.  Such coordinates represent pints in the X, Y and Z directiotions thus they now serve as the joints of the frames.


Members of the frames can easily be added by defining their position relative to the joints. For example the first column will now be from joint 1 (or 0,0,0) to joint 2 (0,3,0) and simply apply the same principle for the rest of the members.


By playing around with the drop-down menu of the software, you would be able to add loads, support and joint types, the kind of materials, and the loadings. Once you hove done it, just look for the caluclate icon or similar then its done. Find the results command and then you will be able to find the result of the calculations.

Understanding the concept of UCS or user co-ordinate system is very inportant in 3d drawing. In simple terms, UCS can simply be likened into your drawing board. If you put a paper on your drawing board, your UCS is the plane or the inclination of your drawing board hence when you draw a line on that paper, it is similar to drawing a line in your current UCS. If you then recline your drawing board to a certain degree, your UCS will likewise be reclined accordingly.


In using autocad 3d, you can create complex 3d objects by simply manipulating your UCS. If for example you want to draw a pitch roof, then you must change the orintation of your UCS such that it shoudl be on the same plane as the inclination of the pitch roof.

12d is a civil design computer software. It features road design and surveying. It's very powerful. It can create road loayout and sections without going to the pain of manual calculation and painstaking autocad drafting.


The good thing about 12d is that it has a demo version in which one can self-train himself at his convenient time. The demo version is valid for one year. Yes you read it right, it's one year. Unlike other demo sfotwares where you can only try them for thirty days, 12d is good for one year and on top of that you can renew demo license afterw ards. 


Their demoversion is absolutely free,

Marblaze Drawings is proficient in converting your paper drawings into CAD and detailed drawings.


Every drawing is drawn for a particular purpose.  Details shown merely reflect this on a drawing.


There will come a time when an existing paper drawing will be used for a different purpose. Some details shown may have very little or no significant at all with regards to the new intended use of the drawing.


Marblaze drawings can convert an old paper drawing into a new and presentable CAD drawings.


Below is an example of a converted paper drawing into CAD well presented and details hown are carefully selected and added to suit the new intended use:
