Post 52B — LibreCAD Tutorial 4 – Dimensioning.

Dimensioning is the most not-fun part of CAD, but a necessary evil. Dimensioning is necessary because it provides the information necessary to build the object shown in the drawing. It is the most detailed part of creating the drawing and if you are not careful the dimension lines can create a mess out of the drawing.However, many people find it the most rewarding part of the drawing because it is the part that actually finishes the drawing and makes it an attractive drawing.

I usually create drawings only for my use and do not put as much care into dimensioning those as I show in this drawing.  However, some of you might want to create plans to share with others so we take it to the boring details.

In this tutorial, I first clean-up an over-sight in the previous drawing and add a couple of lines. Then we proceed on to doing actual dimensioning. Step one will be changing the settings in the dimension tab of the current drawing settings. Next we will start doing the actual dimensions. It is very important to use the positioning snap settings when dimensioning, to have accurate dimensions.
In this part I do the horizontal dimensions for the drawing.
Tutorial 4 had to be cut in half to fit within the YouTube length requirements. Unfortunately I discovered this late in the process so the cut is not exactly smooth, but I was able to get the video out.
Part 2  picks up right where Part 1ends and moves on to the vertical dimensions. Next we look at the radius and diameter dimensioning functions and dislike those and use the leader and text instead.

The last part of this is the “prettying-up” of the drawing by changing the dimension extensions so they do not cross over the part and confuse someone looking at the drawing. To do this we use the modify – explode function to break up the dimension into separate entities so we can modify the parts and pieces of the dimensions.

We only have one more tutorial left to finish this basic drawing. That will be printing the drawing and making it a paper drawing we can use to build the actual part..

This particular set videos was very hard to get out for some reason. Murphy of Murphy’s infamous law seemed to be having a party with me today…. if it could go wrong it seemed to always do so. But I GOT IT!
