Modify the grips' number of the Polar parameter in the section symbol dynamic block in the last example to display both of the two grips of the Polar parameter. From the following picture we can see that the central grip is clearly different... Read More

In this section, we are going to use a rotation parameter and rotate action to add a dynamic rotate function to view index symbols (English system) which are frequently used in architectural drawings. 1. Draw a drawing Draw a view index symbol and... Read More

Scale Action can be matched with the Linear Parameter, Polar and XY Parameter to achieve various Dynamic effects. Linear Scale 1.Draw Finish drawing an access hole in a model space and define it as a block, as shown in the following picture.   2... Read More

Take the 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 the smaller diameter shaft after stretching, as the following picture shows: Then, we use the "Distance Multiplier"... Read More

Actually, limited to the demand of the material mechanics characteristics, keyway is only allowed to be placed on the central line. So, a horizontal movement is enough for keyway and the movement to other direction is not meaningful. Next we will... Read More

Alignment Parameter can give dynamic blocks the function of alignment automatically, which can save the step of rotating the blocks. 1. Add a alignment parameter for a roughness symbol Draw a roughness symbol in the Block Editor (BEDIT). Select the... Read More
