Ok the string that I have been talking about my last couple blogs I’m going to explain to you step by step how one would draw and object using a string. Basically what you are doing with the string is replacing it with a ruler that you yourself have set the units to what ever you need while you are drawing.
This is your string and when you are using it how the string is meant to be held in your hand. Remember your elbows must be in and your feet must be in the same position so your view does not change and your image will stay accurate.
- First step would be to mark the center of the page. This is where the center of the object will be also.
- Then find the center of the object we are trying to draw with the string we find the highest point (holding the string in a straight line vertically) and the lowest point. We then pinch that off and fold the string in half and put it up against the object again. This will give you your half way point on your object vertically. When using the string technique you must always keep in the same position so the angles do not change and you must also keep you arms and elbows straight. We must also keep one eye open while using the string to measure the angles.
- Then you must repeat this step horizontally so you can get the width of the object and then its center. Where the center of the horizontal and vertical lines meet is the center of your object and is where you should place your first line on the paper.
- We draw that line by taking our sting and lining it up to on the object remembering to keep our elbows straight. When we have gotten our line and the angle the object is we look at our string and observe the angle and then draw the angle that we have just formed with out string on the paper.
- After we have drawn that first line and we have checked that the line of the angle is correct we then move on the getting the proportions correct. We have to arbitrarily pick a point of the page and mark it to be the farthest point on side by marking a vertical line. For example on our chair, that point on my object was the furthest corner of the seat to the left. So I knew that my corner was going to be drawn there. I then know, because I have drawn my center point on my paper that from that point to that corner is half, so with my string to that corner to the center of the page I measure out that length by placing the string onto my paper and pinching off that length. I know then the other end must be the same length from the center just on the right. I mark that on my paper and make sure it will fit and the image I am trying to draw is not too big of to small.
- We now need to measure the units so we can get our proportions correct. Again we pick a width of say the lip of our chair and draw it. We have to draw it to what we think looks like the right size because the next point of our drawing will be drawn using the width as a unit. We look at our object and I picked the width of the lip of the chair as one unit. With that one unit I pinched off on my string I measure how many of those units are in the width of my seat above the lip that I am trying to draw. If I count 4 I go to my drawing and where I have arbitrarily drawn that lip of my chair I measure that unit off and the count 4 of them so I get a point on my paper were I should draw my new line at that angle.
- We repeat these steps of measuring units off throughout our whole drawing to keep put proportions correct. When we measure a unit it does not have to be the same size unit (for example it does not have to be the lip of the chair). Say we want to measure and see how far up the back of the chair should be and I don’t want to use the lip of the chair because it will be to many small units to count. So we use the whole seat of the chair from the left side to the right side which is a larger unit but still can count as one. I place my string on the object in my same position with my elbow and arms straight, I mark of by pinching the string for the length of that unit and then count how many of those length or units are in the back of the chair and this will then give me the height of back of the chair. After I get the height and count 2 and a half I go to image I have drawn and pinch off on my drawing that one unit (which is the seat of the chair) and from the bottom of the back I count 2 and a half units and then mark of on my page the hight of my back.
