Is there a good way to scale objects so you can maintain proportions?

Examples would be a symbol or a hammer. Suppose I wanted to make a 3’ tall hammer but maintain the correct proportions. Or if I found a symbol doing a google image search how would I make that lager?

I have searched all of google and cant find an example.

Its called magnification. You can do it on a computer or with a pantograph.

You mean a symbol like this?

Harder for a physical object but for an image a vector graphic program like Inkscape will scale up or down without changing line thickness.

I’ve used the scale tool in sketch up with some success when drawing projects, have to get better with my components but usually can get the numbers to do what I want, when I re-size a top or a face frame etc.

I scale up images from the internet using “Paint” which is in Microsoft.

Insert the JPEG image into Microsoft word and then resize the image by dragging one of the corner “handles”.

I use Photoshop. You can query the size of the image in inches for this case and then tell it to resize to whatever size you need. I often resize to larger than my printer can handle, so I crop the image into multiple parts that I can print and then overlay them to get the pattern I need. It is my understanding that you can do this with Inkscape as well and Inkscape is a free program

Old school by using a grid, a pantograph, an overhead projector; new school is woodgears big print.

Ok looks like I should be able to use GIMP to scale up my project. I can’t print it out at work so I will have to wait till I get home. Thanks again for the suggestions.

I have a cheap overhead projector that I have used on some jobs. It came in handy when a person sent me a picture of the table they wanted built, but no dimensions. I was able to mark out the height I wanted on a piece of paper and then project the picture of the table leg and play with the image until it just fit the measurements. Then I had a pattern to use for the legs.

If the final image fits within an 8.5×11 rectangle, I paste the image in question into Word. Then click the image and grab the corner to stretch the box to the correct size. Sometimes you have to hold the Shift key to maintain the proportions.

Using inkscape worked. I had to save it as a pdf then when printing it as a pdf you have to select titled printing ( or something like that I am not looking at it at the moment)

Have your say...
