How to Input Accessory Blocking in MiTek with 6 Easy Steps

How to Input Accessory Blocking in MiTek with 6 Easy Steps

Sometime last year, we acquired a customer seeking to have multiple apartment complexes designed. In the process of designing these buildings in MiTek, the one monotonous stumbling blocks I kept running into was blocking panels for the roof. It was taking an absurd amount of time to manually put in each individual block.

Depending on the size of the building, it could take a couple of hours or longer. Two hours plus just for blocks! I thought to myself, this is a bit ridiculous! There has to be a better way. I started messing around with the roof truss accessories button. Eventually after about 15-30mins I figured it out.

There was a way to put in roof blocking just like floor blocking. I was about to turn a few hour job into a fraction of that. In the following sequence of photos, you will see step by step of how to use this button and hopefully help save you much-needed time on your next job.

Step 1: Locate the “Roof Accessory” button and “Property Box” set up on your toolbar. NOTE: Be sure in the properties box to select truss instead of dimensional.



Step 2: You will need to follow the prompt windows instructions until you get the hang of putting them.


What this is telling you is to select where the blocking is to be located. For example: A wall or beam. You will see in the next photo how the wall is highlighted where I want blocking to go.

Step 3: As I mentioned before, in this photo, the wall that needs blocking is highlighted. With this step the new instruction in the prompt window now says to select a roof plane. Keep in mind during this step, a roof plane is not just considered the actual roof but also the ceiling plane or piggy back plane can be selected as well.


Step 4: During this next step, the prompt window gives instruction to select a reference line. By this, the MiTek software wants to know the defining edge of the blocking. If you skip ahead to step 5 you can see the horizontal dashed line that is the line that represents the defining edge.


Step 5: In this step, the prompt window says to select the start line. This means the software wants to know where the blocking is supposed to start going left and right or right to left.  If you skip ahead to step 6 you can see the vertical dashed line up against the vertical girder that represents the start line.


Step 6: This is your last step, selecting the end line. This means to select the distance you want the row of blocking to go.


End Result: Now assuming you clicked all the right spots, you should get something that looks like the following picture. I have learned the software is very touchy and sometimes it can take a couple of tries to get the blocking in. So don’t feel discouraged if it doesn’t work for you on the first try. The key is to be very careful with your line selections.


Hopefully after following this step by step guide, it greatly helps you as much as it has helped me. Not only has this amazing tool allowed me to service my customer better, it has allowed me to shave a tremendous amount of time from each job and allow me to move on to the next one!
