![]() ![]() ![]() Will also expand or shrink as the target surface expands or shrinks. You could put in several profile curves for a sweep with some smaller and some larger to make a tube like that, but a moreĬonvenient way is to use the Transform > Deform > Flow tool which can map an object from a base plane onto curved surface. In the narrow waist area and expand in the top. Making a tube using Sweep but I found that you don't want a regular tube because you want the grooves to shrink down I thought it would be good to put in a tube and use boolean difference to cut out grooves. This is kind of what you want to be shootingįor with NURBS modeling, I mean making large simple chunks of your model out of a small number of 2D profile curves. So that's all you need to make the base shape, just one profile curve and one command. Then Construct > Revolve, with the revolve axis along the open ends: The Revolve tool can be good to make a cylindrical type shape like that. With this method you temporarily ignore the wavy shape and instead focus on a base underlying surface form. Here's a different method though using a sort of "structured drawing" approach. 3dm model file so I can take a look at what you've got? Well from a glance it does not necessarily look like you couldn't do it that way with lofting. > This is what I have been trying to model in Moi3D You can even select the result and give it a Twist:īe sure to come back and post what you made :) ![]() Output as a STL file and you're ready to print! Rail Revolve the blue "profile" around the magenta "rail". Want thicker walls or a thicker bottom? Just select the points on your the profile curve and edit as needed. Notice how the rounded top edge flares out just a little. In Right View, draw a closed Profile Curve (shown in blue). If you want the interior flutes to be reduced, just offset your small circle toward the inside of the larger circle before performing the circular array. Circular Array the small circle around the large circle. Start by making the "Rail" for the Rail Revolve:Ĭreate two circles. ![]() However, I think a Rail Revolve will give you the greatest control over the design, especially how the fillet is formed on the top edge. Computer predictions of blood flow and oxygen exchange executed on synthetic large-scale network models are expected to elucidate poorly understood functional mechanisms of the cerebral circulation.My first thought was to use a Loft to make the vase. Specifically, computed tomography and two photon laser scanning microscopy data are input into the novel synthesis algorithm to build the cortical circulation for the entire mouse brain in silico. A second critical innovation allows the incorporation of detailed anatomical features from image data into vascular growth. This overcomes shortcomings in existing algorithms which are unable to create closed circulatory networks. At the microscopic length scale of individual capillaries, we present a novel synthesis method for building anatomically consistent capillary networks with loops and anastomoses (=microcirculatory closure). It addresses two critical deficiencies in cerebrovascular modeling. As a precursor to the human brain, this paper presents a computational framework for synthesizing anatomically accurate network models for the cortical blood supply in mouse. Microcirculation plays a significant role in cerebral metabolism and blood flow control, yet explaining and predicting functional mechanisms remains elusive because it is difficult to make physiologically accurate mathematical models of the vascular network. ![]()
