I am going back and forth trying to get a body extruded to a precise length 1016mm. But everything I do gives me a fraction. When I try and remove just that fraction it removes some other value larger ( i am using the pad to key in my values). It looks like it might be double but not always. I assume this is a bug? I am using an iPad.
What would be useful, and maybe there is a way to do this that I have not found, is to be able to set the precision. For example if I am working in mm, for my application, I don’t need things moved, sized or positioned in fractions of 1mm. I understand others might.
OK. I just tested this with a body that has square or rectangular face. When I try and resize I am always give the option to enter the whole size. After I chamfer the edge to 45 degrees - I am making mitered carcasses - I am given the option to move the face by an amount relative to the current size. When I do that shapr starts to introduce rounding errors, that after a few attempts devolves into full on errors.
For example. If I have a panel that has an outside edge of 450mm and inside edge of 430mm, I select the top face and reduce the size by -10mm my outside edge is now 435.858 the inside edge is 415.858, the material is 20mm thick. I expected the outside edge to be 440mm and the inside edge to be 420mm.
I already sent you a model. Here are three screen shots. You should note that the new size is random, or maybe a ratio of the size of the panel I am sizing.
This is the expected behavior. Using the offset operation offsets a face in the direction of its normal, so when you are offsetting that face it won’t move in the Z direction. If you want to move that face in a certain direction, you can use the Move/Rotate tool to move it.
Fine. But can I move it with precision? I mean sometimes it is out by 5 or 10 or 50mm. I mean I need to make that board a certain length. Otherwise how can I layout the furniture for with any accuracy. And this is simple stuff.
No, that’s not what I mean. Offsetting 20mm a 45° chamfer will shorten your edge on the side by exactly 10 * √2. Offsetting does not move the face in the Z direction, but in the direction of the normal of the face.
