![]() Change the X offset to 80mm, and the Y offset to 90mm.Īttachment offset is commonly used in conjunction with expressions to offer a parametric parallel to plane position, eg. ![]() Look further down and find attachment Offset and expand it, by clicking the plus sign next to it.ĭo the same for the Position sub heading. In the combo view (Data tab), look in the Attachment section of the properties pane, here we can see that BaseSketch has a support of XY_Plane and is attached with mode Flat Face. If we leave the sketch where it is, the example would be too easy, so let's change the sketch's position by altering its attachment offset. Select the sketch, press F2, and rename it to "BaseSketch". Sketch a rectangle, centre it on the origin, constrain with a (horizontal) length of 70mm and name it "length", further constrain it with a (vertical) width of 40mm, and name it "width". When you select the plane to make the sketch on, that is in fact what is being done, the select plane dialogue is just simplified version of the attachment dialogue, where all offsets are set at zero. Switch to Part Design workbench, open a new document, create a body and a new sketch on the XY plane. We will start with a block and remove the excess with a pocket. We could include a trimmed corner in our base sketch, but let's forego that and include an extra sketch and pocket, for learning purposes. ![]() We could make a sketch on any of the major planes. In some models that would be a wise choice, for the sake of this tutorial we will confine ourselves to Std Planes and sketches. It is perfectly possible to create some Data geometry here and attach all sketches to it. There is however an obvious axis from which all features are common. See Feature Editing for further explanations.īefore we start let us examine how, we should go about building this model.įrom whichever angle we look at it, we see a square or rectangle with a corner trimmed off. The purpose of this tutorial is to show how a model can be constructed by positioning sketches relative to other geometry using some of the various attachment modes available.Īlthough it is possible to use solid geometry (Vertices, Edges and Faces) for reference geometry, in the interest of what is considered good practice, this tutorial will refrain from doing so. Have a basic understanding of Expressions.Have a basic understanding of the Part Design workbench.Be able to make and constrain a sketch.Aminul Islam and downloaded from here:- as "Practice - 13".īefore attempting this tutorial users should :. However, things may differ in some details. This tutorial was written for V0.19, but should be valid for any version 0.17 and later. This links the two objects' placement properties, the attached object will then follow the original(if its placement is changed.) The focus is on Part Design workbench and attaching sketches to other sketches, this being a recommended method for making stable models. This tutorial should serve as an introduction to Part:Attachment, it is not comprehensive, but hopefully will help users experiment.Īttachment is a utility to attach an object to another one.
