We have a YouTube video that demonstrates this concept as well. With Zonal selected, the chosen planes divide the bounding box of the part or assembly into multiple sections, by clicking inside the selection box beneath the Zonal option, you may now select one or more of these zones to be the cut away section. With these steps, you’ve created a simple Core and Cavity for a mold. Once the cut is made, hide the surface we used to cut, and you can now save the file out as Cavity, with a quick edit of the direction in the Surface Cut, you can easily save out the other side as Core. With that surface created, use the Cut with Surface option to cut the mold into both Cavity and Core. Under the Surfaces tab, use the Extrude Surface feature and expand the line through the part. To do this, we will need to create a sketch on the side of the moldįirst, create a sketch on the left side of the mold. Next, we will need to create the parting line we have the Core and the Cavity. With the Body of the mold created around the part, and again, making sure to de-select Merge Results, we will work on the next step which is using the Combine feature to make a cavity for the part to be molded in.īelow is the cavity, but we still need to do more. The process is much the same as above, but this will require covering the entire part.Īs with the previous Combine example, you will find the part and then create a body that covers the entire part. The Combine tool really shines when it’s being used to create molds. When we section the body, we now have a cutout of the threads after using the Combine feature. With the secondary body created, use the Combine tool to cut out the negative space in the cube. Draw the required sketch from the sketch tab ( ie: the cut profile you want) - go back to features tab - click extruded cut - Input the length and direction. You just have to select the face or plane on which you want to cut the shape - Take the Normal. By unselecting this, we ensure the parts are separated making the next command easier. The extruded cut feature is in the top left tab on Solidworks. Make sure to uncheck Merge Results as the default for SOLIDWORKS is to merge the bodies. Assembly Layout Sketch Evaluate SOLIDWORKS Add-ins SOLIDWORKS FB H Assem (Default The Combine feature in SOLIDWORKS is a great tool used most often in surface modeling as it allows you to take molds of created parts for mold operations.
