If you want to realize symmetric stretch keeping keyway center no change and the length of smaller diameter shaft changes with stretch at same time, how will realize that? 1. Add Stretch for Step Shaft: Add stretch parameter and action for step shaft... Read More

Take step shaft as an example, if we stretch the left part of the step shaft and the keyway still is at the center point of smaller diameter shaft after stretching. As the following picture shows: Then, we use “Distance Multiplier” property of... Read More

 There is an easy way to realize the two-way stretch which is adding two stretch actions. Though it can realize two-way stretch, the action of stretch is independent. The parameter needs some additional setup to realize the two-way symmetrical... Read More

For mechanical design, we often need stretch the keyway to a certain length. Now, let us see how to realize the accurate stretch. 1. Pick Linear Parameter: In block editor, pick the linear parameter, then click entry frame which is in the right... Read More

Alignment Parameter can give dynamic blocks the function of alignment automatically, which can save the step of rotating the blocks. 1. Add an Alignment Parameter for a Roughness Symbol: Draw a roughness symbol in the Block Editor. Select... Read More
