How to cut segment out of 3d object?

[Mason Dixon]

The only way I know to remove the segment of this 3d object in between the orange lines is to slice on each orange line and select to keep both sides which is pretty tedious since I will need to do this every 3 feet over a 170 foot span....is there another easier way to do multiple mortar joints on a 3d object like this?

You might try the Slice command with the Surface option as one method. There are probably two other ways to accomplish the same task. Wait. The other suggestions should come fast and furious in just a few moments.

 

Another option is to create a separate object of the same size/shape of what you want to remove from the first object, position it correctly, and use the Subtract command.

 

Question. Are you cutting completely through the object or just removing a portion of it? Just curious.

Why not create a single section of the extrusion and then array along the 170' ?

 

Or make a solid to use to subtract from the extrusion, but array the solid first and then use the subtract command.

I will be cutting all the way through.

 

I've never done a 3d array. The way I have to do these drawings is to make an outline of the plan view of the building we will be putting decorative concrete banding on. Then I draw my profile and sweep it along the plan view path. This job is easier than others in that there are no breaks for doors windows which would be varying intervals along the plan view.

 

I guess what I'd like to know if there is a way to have a command in autocad that will segment a 3d object I choose and put 3/8" mortar lines every roughly 40 inches.

That's how I would do it.

 

If possible I would have in the beginning, created an individual block and mortar and used array to build what ever it is you are building, if I needed to show it as individual blocks. If all you are after is showing a 3D object that appears to be made from blocks, you could have just applied a material.
