![]() ![]() The final step shows how a corner patch is needed in this case to connect the pieces together:įillets tend to be a complex area of calculation, and places that have small slivery surfaces or a lot of edges coming together at one shared point will tend to increase the chances that the fillets will fail to calculate. Here is an example that won't work, notice the hole that would be created if this were attempted to be filleted with straight corners. The Straight corners option controls whether rounded corners will be placed where fillets meet, or whether the fillets will be extended to intersect each other directly:Įnabling straight corners will cause failures in some situations where the fillets do not directly intersect each other when they are extended. The blend options show a slider that can be used to adjust the amount of bulge. The Shape: option controls whether the fillet will be shaped as an exact arc or as a more organic blend type shape. If you want to type in a value, it is not necessary to click in the Radius edit box first, you can just start typing and keystrokes will go there. Selecting a single curve that has corners in it (for example, a rectangle curve) will allow filleting of some or all of those corners.Īt the "Pick fillet radius" prompt, you can either click 2 points to define the radius as the distance between those 2 points or enter a radius value directly. Selecting 2 curves will create a fillet between them, extending or trimming them if necessary. Selecting 2 individual surfaces will perform a surface/surface fillet operation, instead of an edge-based one. Selecting faces of a solid will fillet all the edges that belong to those faces. Selecting edges of a solid will fillet just those edges. Selecting an entire solid object will fillet all edges of the solid. History is available for this type of intersection, so you can adjust the curves and watch the 3D result update.Īnother example of combining 2D profiles - final stage shown after using Fillet to round the sharp edges:īoolean Intersection can also be used on curves that are all in the same plane to create a curve result:įillet is used to round off sharp corners.įillet will apply the rounding in different ways depending on what is selected. For example, here 2 curves are intersected to create a basic blocky car shape. ![]() In a sense this is the opposite of Boolean difference, which would instead drill a star shaped hole through the sphere.īoolean Intersection can also be useful for creating a quick blocky 3D model that is the combination of 2 2D profiles arranged 90 degrees to each other. Here is an example of intersection between a solid and a 2D curve. 2D curves that are all on a single plane will generate a curve result, or 2D curve profiles on different planes can be combined to generate a solid result. ![]() Solids can be intersected with other solids, surfaces, or curves, and 2D curves can be intersected with each other. Select one set, run Boolean Intersection, then select the other set. Objects to be intersected are treated as 2 different sets. Closed curves can also have other closed curves nested inside of them to form hollow 2D regions:Ĭombine objects together, only keeping areas contained by all objects. Select and delete any pieces you don't want to keep (result shown slightly separated for illustration):īoolean difference also works between curves that are all on one common plane. This will slice the solid into multiple pieces. It is also possible to difference a solid with an open non-solid surface. Here is an example of a solid being differenced by a set of 2D curves:Īnother example of solid/curve Booleans - here the solid is being cut by line segments, resulting in smaller sliced pieces each of which is a solid (result shown slightly separated here for illustration): It is not necessary to extrude 2D cutting shapes into solids if you want to cut all the way through. It is also possible to difference a solid by a 2D curve directly, creating a solid as the final result. It is also possible to cut a 2D curve using another 2D curve.Įxample of Boolean difference between solids: For example, a solid can be cut by another solid, surface, or a 2D curve. Select the objects to be cut first, then run Boolean Difference and select the cutting objects.ĭifferent kinds of objects can interact with each other. Cut an object by subtracting another object from it. ![]()
